In presenting to the public the long looked-for Flora of the late lamented Dr. Bromfield, the Editors feel that a few, and but very few, observations are required from them in expla- nation. Dr. Bromfield became resident at Ryde, in the Isle of Wight, in the year 1836, and shortly afterwards conceived the idea of preparing a Flora of the Island. He was not content to follow the usual practice in the making of local Floras and Faunas, and to be satisfied by presenting merely a tolerably full list; but he determined that the investigation should be very complete, and that every species should receive an origi- nal description. Nor was he satisfied with a mere cursory research in the framing of these descriptions, or with copying any character from other authors unverified by his own exami- nations. He was also equally careful to avoid describing gene- ral characters from individuals or varities, and endeavoured, with immense and most persevering care, to select such points as are really the permanent and essential characters of genera and species. To ensure this result he was in the habit of obtaining a very great number of specimens of each species, collected from various localities; and, whenever practicable, he endeavoured to compare Isle-of-Wight specimens with those collected at a distance. Having thus secured sufficient mate- rial for investigation, his next aim was to consult every author within his réach for all the characters which different observers had noticed. For this part of his plans he had collected a vi EDITORS’ PREFACE. very ample botanical library, especially of foreign authors. The characters, however, observed by others were, for his own descriptions, merely suggestive ;— none being recorded but such as, after careful examination, he himself found to exist in nature. The results of these careful investigations were the. most accurate and elaborate descriptions which can well be ima- gined; but such were the time and labour bestowed on each species,—as much as many authors would give to a genus or family,—that this circumstance very materially retarded the progress of the work. Unfortunately, also, when the Isle of Wight had been very thoroughly investigated as regards sta- tions, and the work of describing was proceeding, the author enlarged his plan, and determined to comprise the whole county of Hampshire within the scope of his Flora. This certainly would greatly have added to the value of the work, had he been spared to complete it; but, such not having been permitted, it is impossible not to regret the interruption which the search for localities in this new field occasioned to the description of species. Another cause of interruption to the present work must also here be mentioned. Dr. Bromfield had an intense love of travel, and this desire ever and anon prevailed, and occasioned a suspension of the Island Flora. Extensive tours through the Islands of the West Indies, and through Canada and the States of North America, although they contributed most valuable information to the pages of the ‘London Journal of Botany,’ very much impeded the progress of the present work. Finally, in 1850, Dr. Bromfield started on an excursion to Egypt, Nubia and Abyssinia; after which he was tempted to prolong his tour into Palestine and Syria, where, alas! he was cut off by fever at Damascus. Under these melancholy circumstances the manuscript of the unfinished Flora was committed to the Editors by Dr. Bromfield’s nearest surviving relative; and here, perhaps, the manner in which they have endeavoured to do their duty, both to her, to their deceased lamented friend, and to the public, requires a few words of explanation. Té soon became evident, notwithstanding the great amount of labour and research bestowed by the author, that the work yet remained in a very fragmentary form. As a Catalogue, EDITORS’ PREFACE. vi and as regarding the detailed account of localities, the manu- script was complete; but the hiatus of descriptions were very numerous. Jn many cases, also, the divisions of families and of the larger genera were indicated, but the characters of these sectional divisions not expressed. The Editors were most unwilling to mix up any original co-authorship with the work of their deceased friend; and they have therefore filled up all these blanks, to the best of their power, by quotations from other published works which the author himself had been in the habit of consulting. They have not bound themselves, in this, to follow any one author; but they have in each indi- vidual case selected that published work for quotation, which it appeared, by the context or by the sectional divisions, the author was in each instance most nearly following. All these quotations are acknowledged by inverted commas in the usual way; and in those very few instances where the words of others would not suit them, or where new plants or localities had been given them, the Editors have indicated the introduction by inclosure within brackets. This plan has of course occa- sioned, in some cases, a little want of uniformity in defini- tions; yet it is thought that this will not occasion any real inconvenience, and that the plan selected is, under all the circumstances, the best which could be adopted. It does not seem necessary to add a list of the works quoted or the abbreviations made use of in citing them; the former being such as are known, and the latter sufficiently explicit to indicate the work intended. The Editors feel, however, that one abbreviation requires a word of explanation: owing to their not having been aware, at first, of the work intended, and having themselves uniformly mistaken in the MS. one of the letters used in quoting it, Mr. Drew Snooke’s ‘ Flora Vectiana ’ is referred to generally as B. T. W. instead of B. I. W.;— which must have been intended for the initial letters of the words ‘ Botany of the Isle of Wight.’ The edition of the ‘ Bri- tish Flora’ always referred to, except otherwise stated, is the sixth edition of that work, by Hooker and Arnott; and that of Babington’s ‘ Manual,’ the second edition; these being respec- tively the last published during Dr. Bromfield’s last residence at home. While the Editors themselves feel the value of Dr. Brom- Viil EDITORS’ PREFACE. field’s work, and confidently anticipate the like verdict from other botanists, they cannot but be most painfully aware how far, in its present form, it falls short of what it would have been had it come in a finished form from the hands of its accomplished and lamented author ; yet, with a fond hope that it will be found very useful, they close their mournful yet plea- surable task, and commit to the public the long looked-for Fiora VECTENSIS. Krw anp Rypg, May, 1856. THE AUTHOR’ PREFACE. Or all the districts into which England is divided by boun- daries, either natural or political, there is perhaps no one that offers a more interesting or promising field for botanical research than the Isle of Wight; yet, singular as it may ap- pear, hardly any spot ‘of equal extent, within the same distance from the metropolis, has received so small a share of attention, despite the allurements of scenery, its now flourishing places of public resort, and the facility of access, which the frequency of steam communication with the opposite shores holds out as inducements to visitors. Its situation, on the same parallel with the most southerly counties of England, insures it as genial a climate as the latitude will admit of; and, lying, as it does, con- tiguous to, and at nearly equal distances from, the eastern and western extremities of the mainland, its Flora participates in the form peculiar to each of these two longitudinal sections.* * Of species predominant in the East of England, we find Thesium lino- phyllum, Melampyrum arvense, Galium tricorne, Myosurus minimus, Spartina stricta, Calamagrostis Epigejos, Bryonia dioica, Cineraria campestris (?), Rham- nus catharticus, Linaria minor, L. spuria, L. Elatine, Antirrhinum Orontium, Euphorbia platyphylla, Althea officinalis, Asperula cynanchica, Ranunculus Lingua, Specularia hybrida, Campanula Trachelium and C. glomerata, Bupleu- rum rotundifolium and B. tenuissimum, Frankenia levis, Typha angustifolia, Chenopodium glaucum, Trifolium subterraneum, Pulicaria vulgaris, &c. ; whilst, on the other hand, of plants that chiefly affect the western side of the kingdom, we meet with Rubia peregrina, Iris fetidissina, Corydalis claviculata, Gastri- dium lendigerum, Briza minor, Scirpus Siwii, Androsemum officinale, Wahlen- bergia hederacea, Coronopus didyma, Linaria repens, Euphorbia portlandica and &. Peplis, Pinguicula lusitanica, Cyperus longus, Anthemis nobilis, Cotyle- don Umbilicus, &c. b x PREFACE. The natural (and politically adopted) division of the island into the two great and very nearly equal hundreds or liberties of East and West Medina, by the river of that name, suggested the distribution of the localities or stations for the several spe- cies under two sections, designated by those districts, as facili- tating reference to the map at the head of this work. It will be seen presently that these hundreds differ from each other almost as much in their botanical as in their geological character, and very widely in their more obvious external or physical aspect. The two nearly insulated districts of the island, at its eastern and western extremities, known in former times, and noted in the older maps * as the Isles of Bembridge and Freshwater, have, under these revived names, furnished minor divisions, of no less convenience than the larger in the classification of the above-mentioned stations or localities. Of the pheenogamous plants and ferns described in our Flora, amuch smaller number of doubtfully indigenous or certainly introduced species will be found to swell the list than usually occur in works of this description. Of these dubie cives, some have obtained a right to insertion by prescription and immemo- rial custom, but which would not on that account have saved them from rejection here, had they not become so far com- pletely or partially naturalized as almost to obliterate the remembrance of their acknowledged foreign descent, as in the case of Acer Pscudo-platanus, Datura Stramonium, Linaria Cymbalaria, Papaver somniferum, Borago officinalis, &c. Others, perhaps not less questionably native, haye been retained from the difficulty of striking the balance between their contending claims to admission on the score of naturaliza- tion, and disqualification as suspected or convicted aliens. Of this class are Vinca major, Centranthus ruber, Pyrethrum Par- theniwm, all of which, though more or less abundant and even spontaneous, can hardly be regarded but as escapes from culti- vation, at periods not very far back. To this list we should perhaps in strictness join, so far at least as concerns this island, Cheiranthus Cheirt and Antirrhinum majus, which with us are never found remote from habitations, though occasionally pre- * Vide John Speed, ‘ A Prospect of the Most Famous Parts of the World.’ Lond. 1631, fo).

The line of demarcation cannot be so exactly drawn as that, whilst it shall embrace none but plants incontestably native to the soil, it shall not exclude others for the rejection of which it would be difficult to assign a sufficient reason. After all, we may perhaps with truth assert of this island, in reference to the small amount of introduced or natu- ralized species it contains, that which the philosophical Wahlenberg reports of his own country (Sweden), “Vix enim ulla alia existit terra, tam bene perseverata, in qua vegetabilia spontanea tam prevaleant et ab adventitiis tam parum pre- mantur.” * One chief obstacle in the way of accurately distinguishing the genuine plants of a country from those of extraneous ori- gin arises from the very different ideas entertained of the term “wild” amongst such as contribute to the general stock of information on this head from local sources. With some, the occurrence of a single specimen beyond the precincts of a gar- den or other cultivated spot is a sufficient claim to citizenship; and if gathered in greater abundance there can be, in their opi- nion, no reason whatever for the exclusion of the species. Happily, observers of this class are not numerous, and a little experience soon teaches them more caution in their con- clusions. Others (and these constitute a majority) are so sceptical as to look with an eye of suspicion upon, and even reject as aliens, a large proportion of species that have been long recognized and admitted by common consent into our indigenous cata- logues; and to such it must be conceded that, however mis- taken may be their opinions in many instances, they at least err on the safe side. In accordance with my own views on this head is the practice and opinion of Professor Fries. “Bene novi aliis placuisse hance plantam exclusam, lam additam, in his suo utantur judicio; equidem vero non aliorum commentis, sed me experientie indulgere debui.

Provin. Suec. i. Fl. Scan. p. xii. In a local Flora like the present, the insertion of a few spe- cies of confessedly extraneous origin, provided they are honestly indicated as such to obviate the propagation of error, can be productive of no detriment to botanical science. Such subspontaneous species have bond fide earned a title to citizen- ship, by taking possession of the soil; yet their claim as deni- zens should be admitted with judgment, and only allowed after a tenure of some duration. As a further precaution, it is advisable to mark such interlopers with the brand of Italics, the attachment of an asterisk or other sign of exception, or to allot them a separate place in an appendix. The second of these methods I have adopted, as being simple and most in conformity with the general practice of other writers, and because the amount of such certainly introduced species is too inconsiderable to be worth while throwing them into a page by themselves. J am of opinion that the best and safest criterion for resoly- ing doubtful claims to enrolment is to be sought for by refe- rence to the geographical distribution of the species under con- sideration. The more extended study of this important branch of botanical science would, I am persuaded, go far in removing many of those scruples that are raised against the admission of no small number of our vegetable productions into the aborigi- nal lists. Proceeding on this principle, I have briefly noticed the geographical range of every plant on which such doubt has been or may be cast, referring to those natural limits as pre- sumptive though not absolute proof in favour of admission, being quite aware that the exceptions to the apparent law of distribution are too numerous to warrant our drawing more than general conclusions therefrom. In accordance with the sound principle adopted by the bota- nists of this country in the preparation of general or local Floras, and which our continental brethren would do well in following, every tree, shrub or herb whose sole pretensions to admission rest on the universality of its cultivation, or subser- PREFACE. xu viency to purposes of ornament or utility, has been carefully excluded from these pages.* The custom of incorporating the Cerealia, for instance, and the hardier, more common, but exo- tic, fruit and forest trees with a work professing to treat of * Almost the only national Flora, our own and that of Denmark excepted, that is not more or less burdened with these conventional objects of mere culti- vation, is the admirable ‘Flora Suecica’ of Wahlenberg, who judiciously reserves for an appendix every species of disputable Scandinavian origin, and so presents us with a faithful transcript of the vegetable geography of that vast peninsula. The opposite practice is unfortunately sanctioned by the authority of DeCandolle, which, it is to be feared, will long cuntinue to uphold the abuse. The otherwise excellent general and local Floras of Lejeune, Host, Reichen- bach, &c., and all the older ones, with scarcely an exception, are encumbered with extraneous genera and species. The truly valuable and original trans- Atlantic ‘ Flora Cestrica’ is disfigured by a number of economical garden plants. Nor are our own local Floras free from this defect. The Edinburgh Catalogue of British Plants, which, from being in general circulation as authority for nomenclature, and professing to include a Flora of the district round that city, will afford a fair instance of what has just been advanced. This latter part of its avowed scope and intention gives anything but a faithful register of the indigenous vegetation of the neighbourhood, for, though many species are therein noted as certainly introduced, we are left in doubt whether or not they maintain their ground by spontaneous propagation,—a condition indispensable to their retention on the list with any degree of propriety. So long, however, as we perceive such southern and even continental genera and species as Buus, Castanea, Eranthis, Linaria purpurea, Staphylea, Trifolium incarnatum, Mal- comia maritima, Reseda fruticulosa, and the like, occupying a place in that Ca- talogue, we must hesitate to regard it as a correct indicator of the genuine aboriginal or even naturalized vegetation of that part of Scotland, in the sense to which that term should be restricted. Judging from the total absence of the above species in a truly wild state in this southerly part of England, in which they might with most reason be expected to occur, but where, in fact, one or two only amongst them are even naturalized, and that but partially and incom- pletely, no trifling number of the 970 species composing the Flora Edinensis must he the mere outcasts of gardens, or have been purposely planted or dis- seminated, as I am certain is the case with the Spanish Chestnut wherever it occurs in Britain. Specimens of such worse than dubious natives it may suit the Suciety to have at hand for distribution amongst its members; but, small as is the value to the herbarium of such semi-domesticated examples, for any purpose of scientific truth their indication in a district Catalogue is utterly worthless. If the same lax rule is to be followed out, why not include the ormamental trees of our parks and pleasure-grounds,—the Horse Chestnut, the Spruce Fir, the Lilac, Laurel, and hundreds more? The transition would thence be easy to the orchard and kitchen-garden, in adopting the productions of which we should have the precedent of continental usage in our favour. xiv PREFACE. indigenous vegetables only, cannot be too strongly reprobated ; since, independently of the necessary increase to the bulk and cost of the book, the species so introduced are, from the effects of culture alone, not legitimate objects of botanical description; their original and specific characters being in a great measure changed and obliterated by the operations of grafting, budding, or cross impregnation, with a view to improve or augment their produce. Following the same rule, I have omitted such ligneous spe- cies as, though of native growth within the realm, are found upon this island only ina cultivated condition in parks and plantations, contrary to the practice too often pursued of swell- ing local Floras with species thus domesticated, simply because they cannot be called foreign, though virtually so in reference to the limits within which they cease to grow spontaneously. Nothing is more easy than to make a great display of the vege- table riches of a kingdom or province by pressing aliens like these into the list, or by undue multiplication of species from casual varieties or permanent races. Hence originate those bulky tomes of French and German authors, teeming with the laboriously acquired gifts of Ceres and Pomona, which, as they have nothing to do with the spontaneous outpourings of the lap of Nature, must be deducted, to form a correct estimate of the vegetative force and features of the country and climate, under the only relation in which these can be either interesting or instructive to the botanical investigator. These remarks will doubtless appear to some persons mis- placed and uncalled for, inasmuch as it may be thought that works of a similar kind in this country are not chargeable with the practice animadverted upon. But if the objects introduced be not exactly the same, the little selection shown in the draw- ing up of too many of our local and provincial lists of plants betrays a latent inclination to extend the catalogue to a greater length than the actual range of many species would warrant. Even in the more carefully expurgated of these productions, how often do we see very exceptionably sounding habitats assigned for certain ligneous species, such as “in plantations,” or, for the various willows, “in osier-grounds,’’—stations which carry condemnation in their very name. If much caution be necessary in admitting the claim of certain herbaceous plants PREFACE. XV to a place in the indigenous catalogue, how greatly more cir- cumspect should we be in allowing those of a tree or shrub, when, from their perennial and enduring constitution, it is always difficult and sometimes impossible to determine whether the hand of Nature or that of man has been the instrument of their dispersion. For plates illustrative of the species, in addition to those of ‘English Botany,’ which are regularly quoted throughout this work, others, in foreign publications, are occasionally referred to when peculiarly expressive of the plants they represent. The beautiful figures in the ‘ Flora Danica,’ * the later volumes of which make ample amends in general for the great inequality of the earlier, and too often, as regards engraving, colouring and nomenclature, disgraceful execution of the intermediate parts, have been consulted with advantage in several instances. In the genus Carex the accurate plates of Schkuhr, with the supplementary ones of Kunze, have been in most cases quoted under each species. The full-sized and admirable delineations in Curtis’s ‘Flora Londinensis,’ and of its continuation by Graves and Hooker, are seldom passed uncited; and I have gladly availed myself of the small but expressive figures of my friend John Curtis, Esq., in his unrivalled ‘British Entomology, as far as they have been drawn from specimens gathered in the Isle of Wight, of which they are the elegant and all but living vouchers. The descriptions of the species were in all instances, with very few exceptions, drawn up from fresh specimens collected in the island; and in those cases where, from the scarcity of the plant, recourse was necessarily had to recent or dried ex- amples from other parts of the kingdom; or, in default of these, to the descriptions of other authors, such deviations from the ordinary practice are invariably recorded, and the sources of information faithfully pointed out, and acknowlegment made when due. That no characters of importance might escape * This celebrated work, one of the most sumptuous and complete of national illustrated Floras, has, since its commencement in 1764, been con- ducted by editors of very unequal merits, as is lamentably apparent in particu- lar portions. Under the able superintendence of the present editor, Vahl, it has more than regained its ancient reputation. xvi PREFACE. unobserved, the descriptions have been carefully compared with those of the best British and foreign authors either at the mo- ment of drawing them up or subsequent to their compilation, always with the fresh specimens at hand for renewed compari- sons in the minutest particular. In this way most of the de- scriptions have been gone over twice, and in many instances three times, often at very distant intervals, and with recent spe- cimens from other stations in the island. In all cases where the abundance of the species permitted it, the account of each has been compiled from a series of indivi- dual specimens, of different sizes, and, as far as possible, exhi- biting every variety of colour and aspect incident to the plant in its normal state. By thus proceeding we learn to distin- guish what is permanent and essential from that which is but occasional or fortuitous in character, and thus avoid the error which, in minute detail and with scanty means of comparison, we run great risk of committing,—the assumption of individual peculiarity for absolute and specific difference. The use of linear measure has been generally adopted in the descriptive part, since size is often as discriminative of natural objects as form or colour. Every one must have felt how imperfect is the idea conveyed to the mind by the most laboured description of a plant, whilst left in ignorance of its absolute or relative proportions. Besides, the same species of vegetable often varies so much in its dimensions under different condi- tions, favourable or the reverse to its development, that com- parative terms of admeasurement, as high or low, long or short, broad or narrow, large or small, lose all their value and signi- ficancy. For all the species described in this Flora, excepting only the very commonest, distinct or special localities are assigned, with a view of saving the too-often hurried stranger, possible loss of time in following up general indications to the object of his search. To the majority of stations for the rarer or more local plants will be found added the date of discovery of the species recorded, which to some may have the appearance of giving an undue degree of importance to their detection, without impart- ing information of practical use or interest to the collector. But when it is considered how rapid are the changes which PREFACE. XVil the surface of this island is yearly, monthly and daily under- going, from the progress of building and its invariable attend- ant, increased cultivation ;—low lands, but lately waste, now inclosed, and spots not long since free, and accessible to every wanderer in search of health or recreation, at this time dot- ted with tenements, their sites fenced from the intrusion of stranger footsteps with the jealous exclusiveness of individual appropriation ;—it will be evident that the first recorded station for some rare or local plant may often be the last on record: the onward course of improvement may have swept such species from our soil, when it becomes a matter of interest, not merely to learn the fact of its having once existed, but, by dates, to ascertain the time up to which at least it was known to have occurred amongst us. By the remoteness of these dates we can in some measure calculate the probability of rediscovering plants that have thus apparently become extinct; since, by how much longer is the interval during which the search for such lost species has been unsuccessfully renewed, by so much are the chances diminished of again meeting with them in their original places of growth. The botanist is thus spared a waste of time and trouble, and his attention diverted from destroyed or exhausted localities to others likely to reward him with the same or even more valuable acquisitions. The flowering time of each species in the climate of the Isle of Wight has been carefully noted from personal observations through a series of years, and will be found often to differ ma- terially from that indicated for the same species in books, where the season of blossoming is commonly made to appear much shorter than it really is, to the manifest detriment of the inex- perienced botanist, who, trusting to the correctness of such indications, is led to look for a species in its perfection in June or July which he might have gathered as fully in blossom in May, or continued to find flowering on in August or Bep- tember. Our times and seasons cannot of course furnish a correct Floral calendar for the more northern parts of the kingdom, though practically applicable to all the southern, and perhaps with tolerable exactness to many of the midland, counties of England. My indications were, however, intended for the Isle c XVHi PREFACE. of Wight alone, and beyond its limits I do not hold myself accountable for their accuracy. When the flowering period is expressed by an interval of three or four months, the initial and terminal mouth, or at least the greater part of each, is to be understood as included in that space of time. So likewise with some of the early spring flowerers: the naming of two successive months denotes that such species may, in favourable seasons, be gathered with con- siderable certainty during the first, and in all ordinary years during the second, month in a perfect state of inflorescence. Besides the flowering, the fruiting or seeding time has been marked for each species, as far as could be accomplished by observations, no less carefully made, although more recently begun.* This adoption of the season of fructification is bor- rowed from the excellent American ‘Flora Cestrica’ of Dr. Darlington, + and though, I believe, nearly a novel feature ina European Flora, { will, I think, be found useful to the carpolo- gical inquirer, as also to the botanical cultivator, by pointing out to them the proper time for collecting seeds in a state fit for their respective purposes. But since the process of matu- ration is in general slow and protracted, and, compared with that of inflorescence (with which, in its later stages, it often advances pari passu), marked by no well-defined period of commencement or completion, the same accuracy of indication is hardly attainable for the fruiting as for the flowering season, depending, as the former does, still more than the latter, on temperature for its advancement or retardation. * [It is to be regretted that the author had, to a very limited extent only, carried out this part of his intentions, although in his MS. a space had been uni- formly reserved for the result of his observations on this head.—Edrs.] + ‘Flora Cestrica, an attempt to enumerate and describe the Flowering and Filicoid Plants of Chester County, in the State of Pennsylvania,’ by Wil- liam Darlington, M.D., 8vo, 1837. ¢ It was partially carried out by Pollich, in the ‘ Flora of the Palatinate.’ INTRODUCTION. From the situation of the Isle of Wight on the southern boundary line of the Agricultural Zone of Watson, we every- where recognize the appropriate features of the latter in the general aspect of vegetation, whether native or introduced. We find the cultivation of wheat predominating over that of all other grain, and producing as plentiful returns on the exposed crests of the loftiest cliffs, or within a few yards of the sea- beach, as in the sheltered valleys of the interior. The Vine and the Fig are common even in the cottager’s garden, the lat- ter always, as a standard, bearing abundant and luscious fruit; whilst, in addition to the more ordinary orchard-trees, the Quince, Walnut and Mulberry ripen perfectly, and produce plentiful crops. Both the narrow- and broad-leaved varieties of the Myrtle (AZyotus communis, L.) form stout bushes in the open air, and mature their fruit in many places, even on the North side of the island and in the cold soil of Ryde, suffering in very severe winters only, and are then seldom more than partially killed back in exposed situations, as many very old and vigorous trunks attest in various places. The Sweet Bay (Zaurus nobilis, L.) attains the dimensions of a tree, and ripens its berries in abundance, resisting our severest frosts, as does the Laurustinus (Viburnum Tinus, L.), which gives to our gar- dens and shrubberies at mid-winter the verdure and bloom of summer, though its fruit is more sparingly perfected. The XxX INTRODUCTION. Strawberry-tree (Arbutus Unedo, L.) is equally common and hardy with the two last, fruits pretty freely, and grows to a tree of respectable size, though inferior to the timber-like dimensions it acquires on its native rocks in the South-west of Ireland, or even in the South-western counties of England, where the greater moisture of the atmosphere eminently favours the de- velopment of this, as of most other evergreens. But if the greater cold of our climate in winter and its greater dryness at all seasons tend to check the luxuriant growth of these and other sempervirent plants, the comparative absence of humi- dity and a less clouded sky enables the increased heat of sum- mer to ripen the wood, and so fit it to endure a degree of frost it would else be unable to withstand. So happily balanced, in the climate of the Isle of Wight, are the vicissitudes of heat and cold to which it is occasionally subject, from its proximity to the mainland and to the Continent of Europe in a degree unusual to insular situations, that the former repairs, or rather counteracts, the destructive agency of the latter on vegetation. If we turn from the aspect of the exotic to that of the indi- genous vegetation of the island, we recognize the abundant pre- dominance of those trees, shrubs and herbaceous plants which Mr. Watson considers as eminently characterizing the climate of the inferior belt of the lower Agricultural Zone, together with many other species scarcely less indicative of the finest wheat region. We here find Acer campestre, Cornus sanguinea, Piburnum Lantana, Ligustrum vulgare, Sambucus nigra, Euo- nymus europeus, Ulmus suberosa, amongst the commonest pro- ductions of our woods, thickets, and the luxuriant hedgerows that bound our fields, and over which Tamus communis, Clema- tis Vitalba, Humulus Lupulus, Rubia peregrina, Bryonia dioica, Lonicera Periclymenum, Solanum Dulcamara and Convolvulus sepium ramble in rich and often oppressive profusion. From its close proximity to the mainland of England, the Isle of Wight exhibits less insularity of character in its Flora than any of the other islands forming part of the British group, scarcely differing, except in the absence of some few genera and species and the greater prevalence of certain others, from the Botany of the opposite part of Hampshire. If we compare the Flora of the Isle of Man, and even of Anglesey, still more that of the Hebrides, Orkney and Shetland Islands, with those of INTRODUCTION. XX1 the counties lying nearest to them on the mainland of Britain, we still perceive a marked disparity in the number of species produced on areas of equal extent in both, the balance being in favour of the latter or continental districts. The same relative paucity of species obtains in the Channel Islands of Guernsey and Jersey as compared with the adjacent coast of France; and this inequality of distribution becomes more obvious the greater the interval betwixt the islands and the main, and the smaller the area of the insulated territory. Even with the advantage of climate which a more genial latitude affords, the Flora of small islands, very remote from larger or from continents, is poorer in species than that of other islands of greater extent and less perfect isolation, though lying under a colder parallel. Thus the whole group of the Azores, although pretty com- pletely explored by the labours of Watson, Hochstetter and others, produces little more than one-third the number of phe- nogamous species afforded by the Isle of Wight, notwithstand- ing their more southerly position, and the far greater variety of elevation which the mountainous surface of some amongst them presents for the extended multiplication of species. * The Channel Islands, though not rich in species for their size, have, in consequence of their less extent and greater dis- tance from the mainland, a more completely insular or mari- time Flora than the Isle of Wight, as the absence from that group of the following rather inland or continental genera and species, found in the latter island, will testify :— Clematis Vitalba Specularia hybrida Thalictrum flavum Rhawuus catharticus Campanula (omnes) ——— Frangula * Mr. H. C. Watson, in his ‘Catalogue of Azorian Plants’ (see Hooker’s ‘London Journal of Botany’ fur November, 1844), makes the total number of flowering species amount to 319, and of ferns to 31, or 350 species in all. A large proportion even of these are common to England and the Azores, and, though some plants no duubt remain unrecorded inhabitants of those islands, the above census cannot be very far short of the number actually existing therein. Even in the tropical Island of Barbadoes, the catalogue of phenoga- mous species and ferns, enumerated by Sir R. Schomburgh, amounts to but 896, and of these not above one-half would seem to be indigenous, the rest being chiefly plants cultivated for ornament or use, with a few that have become naturalized. XXli INTRODUCTION. It is probably owing to its actual, but modified, insularity that the following eminently mainland species, natives of Hants, are wanting to the Isle of Wight, although abounding in localities apparently well suited to their production :— 1.

Dipsacus pilosus 10. Phyteuma orbiculare It is not so easy to assign a cause for the apparently total absence from the Vectic Flora of the subjoined plants, all of which are natives of the county, where, as in other parts of the kingdom, they seem either to evince no particular partiality for an inland over a maritime locality, or, as in the case of some of those now enumerated, decidedly abound most on or towards the sea-coast. These last are, for distinction, printed in Italics. Drosera longifolia Cicendia filiformis anglica Bartsia viscosa Matricaria Chamomilla Euphorbia paralia Teesdalia nudicaulis Lycopodium inundatum Diplotaxis tenuifolia Spiranthes estivalis Isnardia palustris Hypericum dubium Crambe maritima Polypogon monspeliensis Petasites vulgaris Litorella lacustris Centaurea Calcitrapa Cardamine amara To these should perhaps be added Helleborus viridis, Taxus baccata and Lysimachia Nummularia, all of which are confined, in this island, to single and very suspicious stations; those for the first and third have indeed been since destroyed. It may be here observed, that the limitation of any plant to a single locality, and its restriction in that locality to even a single specimen, is, per se, no sufficient reason for its rejection INTRODUCTION. : XXil as adventitious, because it is well known that plants will, in particular districts, where soil, climate or other causes are ad- verse to their increase, continue so scarce as to be reduced to a numerical minimum little short of absolute extinction, and yet pertinaciously maintain their footing if undisturbed. Of the former part of this proposition at least, Cephalanthera gran- diflora and Euphorbia Peplis present, in this island, notable ex- amples; a solitary specimen of each of these having alone been picked, but in situations so exactly conformable to their natu- ral places of growth in other parts of the country, as scarcely to afford ground for their rejection on the score of their pau- city, whilst no exception can be taken to the species them- selves. It is indeed hardly credible that an orchideous plant like the former could have been purposely introduced,* though it is just possible that the latter may have been transported by the waves from the coasts of Devon or Cornwall to the beach at Sandown. All of these, it may be remarked, are rare, or gradually dis- appear in the farthest South-western counties of Devon and Cornwall, and are totally wanting, with many others, in every one of the smaller islands of the British group, excepting 16 and 17, that occur in Anglesey and Ireland, the Flora of which last, its size considered, exhibits in an extreme degree the cha- racter of a western and island vegetation, both in the paucity and peculiarity of its indigenous species, and resembling in these respects that of New Zealand, the Azores, and other island groups lying remote from any large tracts of land or continent. It is observable that Rhamnus catharticus, Bryonia dioica and Campanula Trachelium, three species characteristic of the east- ern and interior rather than of the western and coast Flora of * Every one knows the difficulty attending the cultivation and preservation of the terrestrial Orchidacez, and how little gregarious is the greater number of the tribe. This holds true of Habenaria viridis, which, seldom plentiful at any time on a given station, is in this island so reduced in frequency that I have seen but three, and those collected by others, in more than thrice as many years, during which time I have not once fallen in with a specimen on any of my innumerable herborizing walks within the limits of this Flora. XXIV INTRODUCTION. England, and which are extremely rare and local, if really indige- nous to Scotland and Ireland, show a marked tendency to avoid the coast line of the Isle of Wight in every part of its perl- phery, and to retreat towards the central, and as it were more continental, portion of it. All three are plants eminently attached to calcareous soils,* and, though that condition for their maintenance is afforded them by the extension of the chalk and limestone to several points along the shore, in vain should we look for a specimen of any one of them betwixt the Foreland and the Needles, or from thence along the North side of the island to the mouth of the Medina, within a distance, in most cases, of several miles from the sea-beach. It is true that on the mainland the Bryony at least grows in many places near the sea-beach, but the indefinite extent of country at the back gives such shore stations a comparatively continental character. The following species evince, in the Isle of Wight, a power of occupancy not very greatly superior to that shown by the plants just named, but which are as certainly indigenous as any others of greater frequency and abundance :-— Habenaria, viridis Cladium Mariscus Ophrys aranifera Thalictrum flavum Butomus umbellatus Asparagus officinalis Whilst we may cite, as holding a very insignificant amount of space in our island Flora, Botrychium Lunaria, Lastrea Oreopteris, Asplenium marinum, Spirea Filipendula, Orobanche caerulea, Listera Nidus-avis, Vacciniwm Oxycoccos, Dianthus Armeria and D. prolifer, all equally indigenous with those before enumerated, though concentrated in small quantity on solitary points as it were of the country, or scattered individu- ally over it at few and distant intervals. The absence of a very large, and indeed the greater, propor- tion of the genuine aquatic plants of Britain is a peculiarity in the Isle-of-Wight Flora, the cause of which is manifestly the * The Bryony is found on the green sand in several places S. and S.E. of Newport, as at Sandway, Pagham, Perreton and Redway, as well as on the chalk, to which the two remaining species in question are confined. INTRODUCTION. XXKV want of appropriate and congenial places for their growth and dispersion, which extensive bodies of water afford; something being doubtless due, as we have lately seen, to climate and insularity of position. Omitting a few insignificant ponds, pools and dams, of mostly recent and artificial construction, the natural drainage of the island is effected chiefly by some half-dozen or so of sluggish streamlets, fed by the numerous fine springs with which the island abounds, that break out at the base of the chalk ranges, and find their way, through narrow devious channels, to the sea. The water of these streams is mostly turbid, from the detritus of the rocks they flow over; and their motion, though slow, combined with the depth and narrowness of the channels they pass along, are all unfavourable to the growth of such purely aquatic plants as require the clear, broad, shallow and tranquil element for their habitation. Moreover, the water of those streams that mean- der through the boggy valleys of the Medina and Main River, and of the drains and ditches communicating with them, is contaminated with peroxide of iron from the ferruginous sand- stone, or the decomposition of the pyritic nodules that abound in the chalk and tertiary formations, and which impregnation cannot but be injurious to some aquatic vegetables. From all these causes united it doubtless happens that the following genera and species of true water-plants are strangers on this side of the Solent :— Nympheea (introduced ?) Ceratophyllum ? Nuphar Stratiotes (introduced) Sagittaria Acorus Hottonia Actinocarpus Hydrocharis (introduced) Whilst, of species belonging to genera of which representatives occur in the island, we miss— Sium latifolium Potamogeton perfoliatum (nanthe Phellandrium Nasturtium amphibium 3 fluviatile Glyceria aquatica Myriophyllum verticillatum XXvVl INTRODUCTION. The moderate difference observable in the temperature of the seasons betwixt this island and the northern parts of Britain, that of summer in particular, may well appear inadequate to produce so striking a contrast as we find on comparing together the Floras of Newport and Edinburgh. Other elements, scarcely less potent than temperature, here come into opera- tion, to determine the balance greatly in favour of the former. If the heat of our summer be not very much above that of the North at the same season, it is protracted into an autumn of longer duration, dryness and serenity, better able to ripen the vegetable tissues, and bring the seeds of plants to maturity. From our proximity to the continent, and the greater breadth of the mainland of England along its southern coast than else- where, our atmosphere is less loaded with clouds and vapour than is that over the narrow and deeply indented promontory of North Britain, environed by a wide expanse of water on three sides, without any adjacent surface to arrest the deposition of moisture from the Atlantic, much of which is precipitated, before it can reach this island, upon the peninsular counties of Cornwall and Devon. Hence the amount of direct solar radia- tion, so active an agent in developing a varied and vigorous vegetation, is oftener and more continuously exerted here than at the North, proving more equivalent in energy to the power of a diffuse light, protracted through days considerably exceed- ing our own in length at the season in question. Another peculiarity in our island Flora is the relative scarcity of certain plants characteristic of the chalk formation, as compared with their abundance on the cretaceous deposits of the mainland of Hampshire. We may instance Fagus syl- vatica, Echium vulgare, Cichorium Intybus, and Verbascum nigrum, which are there quite sporadic, and form no prominent feature of the chalk-country vegetation. Our downs are not, as there, crested with picturesque and venerable yews, of un- known antiquity, their precipitous flanks clothed with woods of umbrageous beech, or dotted with dark compact clumps of the more humble but aromatic juniper. The same paucity of indi- viduals is observable in many other plants common to both parts of the county, which, very rare or local in the Isle of Wight, are of general occurrence, or at least are more plentiful where they do occur, on the mainland of Hants, such as Coro- INTRODUCTION. XXVIL nopus didyma, Linaria repens, Pyrus aucuparia, Cochlearia da- nica, Frankenia levis, Chelidonium majus, Valeriana dioica, Verbascum nigrum. Some, however, there are that abound more in the island than on the main, as Ligustrwm vulgare and Rubia peregrina. It might be concluded, from the extent of coast-line which our insularity commands, that the Flora of the Isle of Wight would be particularly rich in marine or littoral plants; but, though our sea-shores are not deficient in species interesting from their beauty or rarity, the geological structure of the greater part of the coast is unfavourable to their permanent establishment. Along the whole southern shore from below Sandown village to Rockin End, and from thence westward to the Needles, the sea washes the feet of the cliffs or the banks of slipped land at their base, on which alone it is possible for any vegetation to fix itself. The cliffs, in most parts perpen- dicular, can afford footing but to few plants, whose tenure, from the crumbling nature of the rock, is very brief and precarious. These therefore are mostly grasses, as Agrostis alba (which fringes the cliffs at Shanklin), or such other small plants as can cling longest to the treacherous soil, or find room to flourish on the narrow water-worn ledges. The slipped banks beneath the cliffs, composed of the débris of these last, and of the clays, &c., of the lower greensand, are hardly more stable, being con- stantly in a state of change from the undermining action of the waves and the percolation of landsprings, often charged with iron, that issue from the face and bottom of the rocks above, which, made more friable by the infiltration of water and the disintegrating action of frost, fall from time to time in vast masses, burying the vegetation at their feet to a considerable depth beneath the ruins. The generally wet and tenacious character of the soil composing these slipped banks is ill suited to plants that love a dry, loose, sandy or pebbly beach, and which would therefore be sought for in vain along the line of coast we have been speaking of. The vegetation (in many places very scanty) that covers these accumulated disruptions is mainly derived from the rock above, whatever that may be, and consequently varies with its geological character in differ- ent parts along the entire line of coast, modified also, in some measure, by the nature of the softer substratum, forced out from XXV1il INTRODUCTION. beneath the superincumbent upper beds of chalk or sand- stone. We may here take a rapid view of the vegetation of the cliffs, and of the slipped land at their base, before proceeding to give a sketch of the maritime Flora of the island, properly so called, from which the former is perfectly distinct. It may be easily imagined that the cliffs themselves, from their friable constitution and perpendicularity, are nearly bare of vegetation, even of the humblest kind, and such is for the most part the case. Some few plants, however, make a shift to maintain their position, and even flourish vigorously, on the bare face of the chalk and sandstone, as did, for instance, F'ran- kenia levis, some years ago, on the naked wall of chalk forming the magnificent arch or concavity of Scratchell’s Bay, till over- whelmed by a fall of loosened fragments from the summit. > ).—Herbs.

Leaves mostly crowded into tufts at the ends of the branches, on the young or flowering shoots alternate or two or three together, oblong-lanceolate, quite entire, thick and fleshy, dull whitish green, flat, very obtuse and rounded at their apex, more or less decurved, the lower leaves for the most part very strongly arched, covered on both sides with fine stellate pubescence, but quite destitute of those callous pedicellate glands which are found on M. sinuata, gradually taper- into thick 2-edged petioles which are rounded beneath, nearly flat above, not grooved. Corymbs terminal, racemose, naked and simple, loose. Bracts none. Peduncles patent or spreading, tomentose, various in length, shorter, equal to or longer than the calyx, nearly erect in seed. Flowers very large and handsome, 1—14 inch in diameter, delicately fragrant’ with the odour of cloves. Calyx oblong, 6 or 7 lines in length, stellately tomentose, purplish.

The delicious fragrance of the wild plant, more particularly of an evening, surpasses that of the cultivated Stock or Gilliflower, of which it is the parent. Though only of biennial growth in our gardens, the Sea Stock is certainly perennial on its native cliffs, as is evident from the remains of the seed-pods of the previous year continuing attached to the flowering branches of the current season. Besides, Jackman, an intelligent clifflsman, whom I have repeatedly employed to procure specimens from their otherwise inaccessible locality, speaks with certainty of many bushes which he has remarked for five successive years, and there are some of very large size which he believes must be at least above seven years old. From their position on the face of nearly perpendicular cliffs having a southern aspect, the plants are fully protected from North and North- east winds, and enjoy the mitigating influence of the sea air, yet they are some- times cut off by spring frosts in seasons like the present (1845) of unusual lateness and severity.

About Landguard farm and elsewhere near Shanklin very commonly, and where I have seen fields sometimes quite yellow with it. W. Med.—Northwood park, plentiful, Miss G. Kilderbee. The whole plant quite glabrous, 1—2 feet in height. Root white, tapering, in the larger plants much branched, slightly pungent. Stem erect, sharply angular, furrowed, branching from the base in old and luxuriant plants, with many erect branches ; in the smaller often nearly simple, purplish below. Radical leuves numerous, spreading in a circle, lyrato-pinnatifid, their lobes roundish, waved fleshy and shining, the terminal one much the largest, roundish, bluntly notched or lobed, the lower ones entire or nearly so: stem-leaves pinnatifid, their lobes becoming narrower as they ascend, and on the uppermost leaves nearly linear ; the lowermost lobe in all is clasping, and produced into an auricle fringed with a few stiff hairs. Flowers erect, bright yellow, in constantly elongating corymbs very like those of the last species. Sepals equal, oblong, obtuse, concave and erect, at first greenish, afterwards yellow, broader and more rounded than in the last. Hypogynous glands 6, namely, one on each side of the two shorter fila- ments at their base, larger, paler and horizontal, and another on the outside of the two pair of longer filaments, smaller, deep green and nearly erect. Style extremely short, not 3 a line in length, always bent to one side: stigma flat roundish and simple. Siliqgues very long (2—2% inches), far less crowded than in B. vulgaris, erecto-patent, on short stalks that diverge at an angle of about 45°, slender, straight, ancipiti-quadrangular, the valves with a strong dorsal keel, glabrous and wrinkled, tipped with the very short obtuse and oblique style. Seeds numerous (often 20 or more in each cell), pendulous, in 2 rows, brownish or yel- lowish, with darker edges, somewhat orbicular, plane on their outer side, gibbous and bluntly avgular on that next the thin membranous dissepiment, covered with depressed pellucid dots, and hence appearing reticulated, twice as large as the seeds of B. vulgaris. This species is generally thought to have been introduced to Europe from the New World, whence the names of American or Belleisle Cress (from the Straits of that name between Labrador and Newfoundland). Be that as it may, no plant is more thoroughly naturalized amongst us than the present, and in no part of Britain perhaps does it abound more than in this island. In America B. precox extends beyond the Arctic Circle. It affords an excellent spring salad, very supe- rior to the common Winter Cress, as was remarked to me by my friend the Rev. Wm. Darwin Fox, who, having been accustomed to the use of the latter in Der- byshire, on coming to reside in this island having unknowingly substituted the former and more abundant species here, though puzzled to account for the diffe- rence, was immediately sensible of having made an exchange for the better. The taste is much more pungent and cress-like, and Mr. R. Loe of Newchurch: tells me it is often substituted by the people of this island for the common Water Cress, being known by the opposite cognomen of Land Cress. V. Arasis, Linn.

In very great abundance and luxuriance on a high sloping field or bank at the West end of Whitepit (chalk-pit), Newport. Root whitish, tapering, very rigid, usually much branched, biennial, or accord- ing to others perennial. It is certainly perennial with us, as the dried remains of the last year’s flowering and still attached stems sufficiently testify. Stem 1 or 2, seldom except where the main stalk is broken off more numerous, from about 12 to 18 inches or 2 feet in height, simple or more rarely slightly branched above, the branches upright, round, slender, rigid, leafy, erect, often flexuose and recurved at the summit, hispid beneath with copious spreading and deflexed, simple or partly forked white hairs, above either quite glabrous or nearly so. Leaves nume- rous, hispid like the stem and fringed with simple or forked hairs, radical ones nodulate, oblong, elliptical-oblong or obovate-oblong, sometimes inclining to oblong-lanceclate or spathulate, scabrous with the tubercular bases of the hairs, entire or with a few distant, shallow, tvoth-like serratures ; stem-leaves numerous, erect but not appressed, sessile, truncate or subsagittate at base, at other times rounded or slightly cordate, their margins often a little deflexed, usually with a rudimentary branch and abortive raceme in the axil of each; the inferior leaves mostly as hairy as those at the root, and entire or more or less toothed about the middle, never near the apex, gradually narrowing as they ascend and becoming less hairy, the highest sometimes quite glabrous aud shining excepting the mar- ginal fringe, very narrow, linear and acute. Flowers small, white, in constantly elongating racemes; pedicels shorter the calyx, patent and glabrous. Sepals erect, purplish green, their margins white, bluntish, the 2 alternate ones oblong, a little gibbous at the base, the other 2 narrower. Petals linear-oblong ov. vbovate- oblong, tapering into the claw, considerably exceeding the calyx, spreading, entire or obsoletely emarginate. Stamens erect, longer than the germen. Hypogynous glands green, 6, one surrounding each of the two shorter filaments and bilobate, another much smaller and roundish, one behind each of the longer stamens. Germen terete, subcompressed. Style obsolete ; stigma round, flat, glanduloso- pilose. Siligues linear, very erect, 1—14 inch in length, by about 3 a line in breadth, compressed, beaded by the projection of the seeds within, shining, wrinkled and glabrous, with a more or less distinct ridge or keel along the centre of each valve, crowned with the stigma. Seeds numerous, wniserial, oblong-ellip- tical or subquadrangular, flattened mostly on the outer side, the inner a little con- vex, reddish brown, with a darker narrow margin which is often a little expanded at the lower extremity of the seed, punctate-scabrous, as broad as the dissepiment.

A variely with unusually large flowers I find in Howingford withy-bed at its northern end, in very boggy ground. I found, May 28, 1845, in a moory meadow by the Medina, below Rookley, a solitary specimen of C. pratensis, affording a singular instance of abnormal deve- lopment. On the lower part of the corymb were several seed-vessels on pedicels changed from their usual linear to an ovate-elliptical figure, so as to resemble the short fruit of plants belonging to the siliculose section of this order. These on being opened were found to contain petals of the usual colour, which in the pods above had burst from their confinement, and appeared as semidouble flowers, the valves of the pod answering to the true calyx. At the summit of the stem the Sisymbrium.] CRUCIFERAE. 35 flowers had the usual appearance, except that the stamens were changed into petals ; and on opening the ovarium of the highest blossom no ovules were disco- verable amongst the mass of petaloid lamine with which the cavity was filled. The lowermost pedicellate pods had doubtless been at first surrounded by the regular floral envelopes, but from some cause had not emitted them at the sutures like the rest. From their verticillate arrangement it is evident that these petaloid expansions were not transformed seeds, but simply a development of the common axis within the ovary into an abortive whorl of floral organs, besides which there were evident rudiments both of stamens and germen in the centre of the bundle. 2.

Leaves mostly crowded into a dense radical tuft, from about 1 to 2 inches in length, oblong-lanceolate, oblong-elliptical or subspathulate, obtuse or slightly pointed, attenuated into a petiole, more or less unevenly sinuato-dentate or nearly entire, often reddish or purplish, in dry situa- tions rough all over with rigid forked hairs from tubercular bases ; stem-leaves few, distant, smaller, lanceolate or linear, sessile, nearly or quite entire. Flowers small, in a constantly elongating corymb which is somewhat lax or drooping at thesummit. Sepals erect, oblong-elliptical, concave, not keeled, glabrous, or with a few hairs at the summit, the alternate ones somewhat pointed and narrowed, the others very obtuse. Petals about twice as long as the calyx, obovate, attenuated into greenish yellow slender claws, the limb white, entire, at length moderately spreading.

Med.—In the vicarage glebe at Newchurch, in considerable plenty. W. Med.—In a field amongst turnips on the summit of St. George’s Down, near Newport, plentiful. The plant persists in both these stations in spite of the plough, but varies in quantity according as the land has been more or less disturbed. Sie Herb quite glabrous with an alliaceous odour when bruised, very similar in ap- pearance to Capsella in its most common form, and excepting when in seed liable to be overlooked on that account. Root annual, whitish, slender and_ tapering, more or less branched and fibrous, or nearly simple, somewhat woody. Stem erect, from a few inches to a foot or more in height, rounded, with several sharp angles or ridges, alternately branched, chiefly in the upper half, or nearly simple. Leaves alternate, slightly glaucous, a little thick and fleshy, radical ones crowded into a sort of tuft, spreading, obovate, attenuated into pretty long petioles, faintly waved or sinuate, or almost wholly entire on the margin, svon withering away for the most part; cauline leaves quite sessile, more or less erect, oblong or oblong- lanceolate and obtuse, the uppermost only somewhat pointed, almost clasping the stem with their short subsagittate bases, the auricles of which are obtuse or pointed, the highest of all entire, their margins sinuato-dentate and waved, the teeth short, acute, with pale thickened tips. Stipules none. Flowers small, white, in corymbs that are much lengthened out in seed, their pedicels slender patent or spreading. Sepals nearly equal, concave, mostly a little spreading, ovate, very obtuse, green with white edges, obscurely 3—5 ribbed. Petals about twice the length of the calyx, obovate, very slightly emarginate, erecto-patent, with narrow greenish claws. Stamens erect, shorter than the petals ; anthers greenish. Hy- pogynous glands 4, one on each side of the shorter filaments which they partly sur- round, small, somewhat triangular and pointed. Germen orbicular, flattened, scarcely exceeded by the decurrent style; stigma flat, glanduloso-pilose. Si.i- cules very large (4 an inch wide) whitish brown, erect on the now much elongated pedicels, nearly orbicular, with a broad reflexed waved border or wing and a deep narrow notch, at the bottom of which is the very minute persistent style. Seeds about 5—7 (4—9 Curt.) in each cell, pendulous, reddish brown, roundish ovate, ‘compressed, deeply and concentrically rugoso-sulcate, very beautiful. The figure of this plant in EK.

About Ryde and various other parts of the island, occasionally. “« Stems solitary erect 10—12 inches high, corymbosely branched above, Lower leaves almost spathulate, all slightly pubescent, as well as the racemes and pedicels,” —Br. Fl. _Silicules about 2} or 3 lines long, brownish white, more or less erect on the widely spreading or partly subdeflexed pedicels, and about equal to them in length, broadly ovate elliptical or nearly orbicular, a little incurved, keeled, rough with vesicular or blister-like risings and the depressions caused by their bursting, convex and very gibbous at the back, less so in front, where the circum- ference is produced into a thin concave border having a shallow emargination at top about equal in depth to the very short minute and not tapering style. Seeds one in each cell, large, brownish red or rust-colour, ovoid, somewhat pointed at one end, thickly and minutely vesiculose scabrous and punctate, pendulous from a falcate process near the summit of the cell at right angles to the dissepiment. 2. L. Smith, Hook. Smooth Field Pepperwort. Downy, stems diffuse simple or divaricately branching at top, lower leaves oblong entire on long slender stalks, cauline lanceolate sagittate sessile and clasping toothed, pouch (silicle) ovate ellip- tical nearly smooth at the back, style about thrice as long as the notch, root perennial.

Med.—Very frequent and luxuriant about Ryde in old clover-fields, &c. W. Med. Fields by the Medina above W. Cowes, near a wood called, I believe, Bottom Copse, rather plentifully. Near Barton farm and on hedge-banks along the Debbourne walk by W. Cowes. By the roadside between Thorley and Wil- mingham near the bridge, but sparingly. Water-gate near Newport, Dr. Bell- Salter !! | Abundantly on both sides of the Newport road near the Debbourne turnpike, W. Cowes, Miss G. Kilderbee. Close to the windmill near W. Cowes, under the garden-fence of the miller’s house. Root perenvial,* whitish, tapering and flexuose, very long tough and woody, usually simple or nearly so, often produced at top into one or more woody caudices. Stems in small specimens few or subsolitary, in the larger plants very nu- merous, from a span to 18 or 20 inches in length, angular and downy like those of the last, with somewhat longer and more copious pubescence, ascending inclining and suberect, or spreading and decumbent, simple or branched only at the summit, the branches fewer, shorter, curved upwards and spreading or divaricate, not as in the foregoing erect and forming a regular corymbose panicle. Leaves broader and shorter in proportion, less crowded and erect than in L. campestre, more deeply, dis- tantly and sinuately toothed, otherwise similar, but the radical leaves are as Smith remarks, more numerous, and persistent even in an advanced state of the plant’s growth, elliptical or elliptical-oblong, on very lengthened extremely slender foot- stalks, entire or slightly waved or toothed. Inflagescence as in the preceding spe- cies, but the flowers are rather larger. Silicles very like those of L. campestre in size, shape and colour, but slightly narrowed or attenuated upwards or more ovate, less gibbous at the back which is much less scaly or blistered and nearly smooth, tipped with the somewhat tapering style, which is very decidedly (about thrice) longer than the emargination. Seeds scarcely above half as large as in L. campestre. * The remains of flower-stems of a former season, with seed-vessels attached, which I have repeatedly found on this plant, clearly show the root to be really perennial. 44 CRUCIFERE.

Cakile.} CRUCIFERA. 45 A much more delicate plant than the last, with very minute flowers, and far more finely divided leaves. Root annual, whitish. Stem spreading on the ground, from a few inches to a foot or more in length, copiously branched. Leaves small, flat, quite glabrous, rather fleshy, deeply pinnatifid, the segments lanceolate acute with a small deflexed mucro, entire or notched. Flowers very minute, greenish yellow, in lateral and terminal racemose clusters that are much elongated in seed. Sepals broad, hollow, rather obtuse. Petals wanting in my Isle of Wight speci- mens, as I remember having remarked in those gathered by me in Devonshire, where Mr. Banks* told me he could not find them. “‘ Stamens 2. or 4, scarcely ever more,” Sm. (whence the specific name of the plant), but I find the full com- plement of 6 in the specimens before me from Cowes, though but two of the fila- ments have anthers, viz., the two longer ones opposite the flat sides of the germen. Filaments much dilated at the base, the 4 shorter ones stand out almost horizon- tally between the sepals, looking like awl-shaped petals. Hypogynous glands 4, oblong, greenish, one on each side at the base of the 2 larger filaments. Style scarcely any; stigma large, peltate. Silicule very small, of 2 round lobes covered with warty prominences, but not wrinkled. This species has perhaps migrated to us from the W. of England, where it is not uncommon. I have observed it at Plymouth growing abundantly in some of the streets in the outskirts of the town, manifesting itself to the passer-by as he treads it under foot through its strong smell of cresses. Though found in Sussex, itis rare in all the South-eastern counties, and I believe never occurs very far in- land or distant from the sea. I have gathered it at Lymington, and abundantly in Treland, about Cork, Limerick, &c. Its geographical range is very extended, being found in various and distant parts of the world, mostly near the coast. In America I have myself seen it abundantly at Charleston, S. Carolina, in places similar to those it affects with us. Division III. Lomenracra. Pouch or pod indehiscent jointed and dividing transversely into single-seeded or (partly) barren cells. XX.

Seeds naturally 1 in each cell, but that in the lower joint often abortive, yellowish, ovate-oblong or elliptical, subreniform, compressed, with 1 or 2 deep longitudinal furrows; that in the upper joint erect, in the lower pendulous. The cotyledons and embryo are beautifully and readily seen in the unripe seeds of this plant.

Fields above E. Cowes, and Sandown bay. W. Med.—Gurnet bay, Miss G. Kilderbee! Root annual, slender, long and tapering, in taste very like the common radish. Stem branched, diffuse or spreading, rounded and rough with bristly hairs directed downwards. Lower leaves lyrate, the terminal lobe very large and rounded ; wp- permost lanceolate, sinuato-dentate, all rough with stiff hairs or bristles. Flowers in corymbs, about the size of those of Sinapis arvensis, but narrower, lemon- yellow or sometimes nearly white, prettily veined with reddish or purple streaks, which though not always conspicuous, may be easily seen against the light, and which serve to distinguish this plant from all other British species of its tribe likely to be confounded with it. Sepals narrow, coloured, erect, a little spread- ing at the tips only, more or less bristly. Petals narrow, with long, very slender claws. Hypogynous glands solitary at the base of the two shorter stamens, quadrangular, with a depression on their summit, those of the longer filaments also single but oblong. Siliqgues in elongated clusters, stalked, curved, striated, with very irregular, often very tumid joints of 2 imperfect cells whose spongy radiating dissepiment becomes obliterated when ripe, ending in a brownish taper- ing beak. Seeds several, ovoid. Cotyledons conduplicate, embracing the radicle at their lower extremities. Mertens and Koch (Deutschl. Fl.), correctly observe that this plant is not really one-celled, as commonly stated. The dissepiment is very clearly seen on cutting the pod across between the seeds, but is often distinguishable with difficulty from the spongy radiations that fill up the cavity. The seeds, which fill the entire area of the pod, seem included in a fold of the septum.
