THURSTON, OF WYOMING SEMINARY. 1892. WILKES-BARRH, PA. ; E. B. YORDY, BOOK AND JOB PRINTER, 1892. IS- BJOLO LIBRA:. o ^7 PREFACE. In June, 1887, the Lackawanna Institute of Scranton published a "preliminary list" of the plants in the Lackawanna and Wyoming Val- leys. The author, Prof. W. R. Dudley, then of Cornell University, brought together the results of his own collecting, and that of several local collectors, also Prof. Thomas C. Porter's discoveries on the adjacent moun- tains. This list, together with the interest aroused by the Institute during its summer school in 1889, under Prof. Dudley, made the present, far from complete, flora possible. The territory included is the same as that of the preceding list, namely, the Lackawanna and Wyoming Valleys and the mountain ranges enclos- ing them. Localities are occasionally mentioned near to but outside these limits to stimulate our botanists, who may have access to them, to a more diligent search. The catalogue has been prepared from the carefully kept notes of Prof. Dudley, made from his personal observations in 1889, 1890, and the autumn of 1891, combined with the results embodied in the printed list of 1887 ; from notes kindly sent him by Prof. T. C. Porter, of Lafay- ette College, the best authority on the plants of Pennsylvania ; and from reports made to him by the different botanists in the valleys. Credit has been given each in the text, the single word "Davis" referring to Mr. R..N. Davis, of Archbald; "Graves," to Mr. W. R. Graves, of Scranton; "Miss Carlson" to Miss Eleanor Carlson, of West Pittston. Plants quoted as "common," "abundant," or "frequent," are so quoted on the authority of these botanists, each in his own locality, aided by the general observations of Prof. Dudley. The classification and nomenclature corresponds, in the main, to that of the sixth edition of Gray's Manual, to which students are directed for a full description of all plants growing without cultivation. The few cultivated plants, noticed for the benefit of my classes, will be found described in Gray's Field, Forest and Garden Botany. Although crowded with the work of his department at Cornell Uni- versity, Prof. Dudley has taken the time to rewrite the families Cistacca, Ericaceae, Cupuliferce, Salicacea, Juncacea, Cyperacea and Graminea:. 755382 PREFACE. He has also read my manuscript upon the other families and given me much valuable assistance and advice. The present flora is but a "report of progress" preliminary to a COM- PLETE FLORA, which will be published as soon as the territory is carefully worked up so that such a flora is possible. To make this work easier the present edition has been made a pocket flora, suitable for field work. Alternate leaves have been left blank for notes and the species have been numbered. The plants believed to be native are printed in bold- faced type, while introduced plants are printed in small capitals. The discovery of a new plant or of a new locality for a plant not marked "common," "abundant" or "frequent," should be carefully noted on the blank leaf opposite the genus to which it belongs, with date, locality, its abundance, and any other valuable or interesting facts. Specimens should be pressed, and preserved either in your own or your school herbarium, and a duplicate sent either to the Lackawanna Insti- tute at Scranton, to Wyoming Seminary at Kingston, or to the West Pittston High School. Credit for all such discoveries will be given in the complete flora when published. Much remains to be done, especially among the aquatic plants of our ponds, marshes and streams. Our summary shows that less than a thousand species of plants are known to grow without cultivation in our territory ; the total should be at least two hundred larger. Many plants believed to be common, as Thalictrum polygamum, are reported from Wyoming Valley alone, others are reported from Lacka- wanna Valley only. Such plants can be easily worked up by beginners, while the more advanced students should form botany clubs, and the work should be given out by families; in this way more rapid advancement can be made both in our knowledge of the flora and in the botanical knowledge of the student. Among the many places, mentioned by the teachers and botanists of the valleys, as especially worthy of a visit, are the Archbald "pot- holes" and White Oak Creek, both near Archbald; Elk Mt., north west of Carbondale; Bald Mt., easily reached from Scranton; Campbell's Ledge, and Falling Spring, near West Pittston; the Ice Cave Gorge above Luzerne; Tilbury Knob, opposite Nanticoke; Penobscot Knob, its summit and southern ledges ; the lake east of Glen Summit ; Lehigh Pond ; Lake Henry ; Sink-hole Marsh, Ararat ; and the pond opposite Duryea. It might be added that a visit to any pond, marsh or mountain PREFACE. will always repay the botanist, while the Pocono Plateau is especially interesting on account of the many northern plants found there. Hearty thanks are due the different botanists who have helped by their contributions to make this catalogue as complete as possible, and whose names occur so frequently in the following pages. I am also indebted to the liberal management of Wyoming Seminary, whose finan- cial aid made the publication of this flora possible. Personally I am especially indebted to Prof. W. R. Dudley, of Leland Stanford, Jr., Uni- versity, whose advice and assistance have been such that all merit that the flora may have rightfully belongs to him. C. O. THURSTON, Wyoming Seminary. INTRODUCTION. Geographically the Lackawanna and Wyoming are distinct valleys, the latter about 25 miles in length, occupied by a short stretch of the great river of Pennsylvania the Susquehanna; the former by an east- ern tributary of the Susquehanna, the Lackawanna river. Topographi- cally, however, they form a single, narrow, synclinal valley, enclosed by the Lackawanna mountain on the northwest, and the Moosic and Wyoming mountains on the southeast, the two elevations coalescing at each end and continuing as a single range. These two ranges curve like a bow, giving the valley between 55 miles long, and in its widest part 6 miles broad the form of a crescent. This depression is also geo- logically of the same formation, and is known as the Northern Anthra- cite Coal Basin of Pennsylvania. The Susquehanna breaks through the walls of Lackawanna mountain into the middle region of this basin, leaving on the south side of this gateway the bold cliffs and rocky terraces of Campbell's Ledge, 750 feet above the river. Immediately on entering the valley it is joined by the Lackawanna, whose source is fifty miles from its mouth, far north- ward of the coal-basin, one branch in the cold marshes of Ararat, Sus- quehanna Co., one amoung the ponds of Preston, Wayne Co. This region, the eastern half of Susquehanna and the western half of Wayne Co., 2000 feet above the sea, is a broad rolling tract of arable but cold land, out of which rise the high isolated mountains of Ararat Peak (which, with Sugarloaf mountain, terminate the northward exten- sion of the Moosic range) and the beautiful double knob of Elk moun- tain, 2600 and 2700 hundred feet respectively. The Lackawanna enters the Anthracite valley by a gap near its extreme northern end, above Forest City, and traverses it to the Susquehanna at Pittston. The latter river, winding through the celebrated "Wyoming Valley,'' passes almost out of the coal-basin, westwardly at Nanticoke, traverses a cleft in the mountain barrier for some miles, turns directly south, cutting quite across its southern end, and passes out below Mocanaqua. This synclinal valley rises from 550 feet above tide at Kingston, 573 feet at Pittston, 740 feet at Scranton, 965 feet at Archbald, 1079 feet at Car- bondale, to 1302 feet above tide at Campbell's Ledge, 2220 feet on Penob- scot Knob, and 2385 feet on Bald mountain (west of Scranton). Its bed INTRODUCTION. is made up of coal measures, overlaid in its upper part by the confused ) nowhere fertile, drift heaps of the great ice-sheet ; in the lower by the soil of a river-plain. Its mountain barriers are composed largely of bold outwardly facing parapets or ridges of Pocono sandstone the mountain- maker of the region separated from the coal measures by narrow bands of Mauch Chunk red shales and Pottsville conglomerates ; eastward, however, the Pocono sandstone of Moosic mountain extends from 12 to 20 miles, forming a broad, elevated tract, known as the Po- cono Mountain Plateau, although here and there on its borders streams cut down through it to the Catskill Sandstone beneath. In general it is a wilderness of cool, tangled swamps, ponds, thickets, woods, of dry barrens and rocks, rough in the extreme, with an elevation of from 1500 to 2000 or 2100 feet, and terminating eastwardly in an irregular escarp- ment of high cliffs, such as are seen near Pocono Knob, in Monroe Co., or the lower parapets which trace its northward trend. The glacial ice- sheet was spread over this plateau, no doubt, although the great terminal moraine of the continent passes across its lower portion. Erosion has left several curious outlying peaks, capped with the hard Pocono sand- stone, and standing as islands, surrounded by a sea of underlying Cats- kill, worn down to a much lower level, such as Pocono Knob, in Monroe Co., the high knobs (north and south) in Pike Co., the four knobs of the Moosic mountain extension, including Ararat Peak and Sugarloaf, in Wayne Co., and the still more distant and elevated double peak of Elk mountain, in Susquehanna Co., the latter the highest moun- tain in Pennsylvania beyond the extreme southwestern section of the State. This Anthracite Valley lies wholly within two counties, Lacka- wanna and Luzerne ; the Pocono plateau occupies a limited portion of five, viz : Lackawanna, Monroe, Carbon, Luzerne and Pike counties, named in order of the largest sandstone area- It is the Flora of this crescent-shaped coal-valley, its mountain bar- riers, the broad, rough plateau into which the eastern barrier blends, and the isolated peaks belonging to this geological formation, which we have denominated the Lackawanna and Wyoming Flora. While we believe it will be of value as a local catalogue, there was an ulterior object in the study, which can only be completely attained with the exhaustive examination of the region. Recalling the facts pre- viously stated, it will be seen that this area has a singularly distinct character of its own, geologically. It lies in the heart of the northern Alleghcnies. It has a great variety of soil. It has considerable variety of elevation ; the effect of a much greater elevation being brought about INTRODUCTION. through the great extent of the plateau. Therefore, from its peculiar position and character, thorough investigation of its native plants ought to throw some light on questions of the geographical distribution of plants in post-glacial times, and the derivation of local floras in the East- ern United States. Final, or indeed valuable conclusions on these ques- tions, we are not at present prepared to give, but shall present those we think our investigations thus far will warrant. To ascertain the affinity of an insular flora, or that of a continental basin, is an easier task than to set forth the exact truth concerning the genealogy of a small flora, one belonging to a series of contiguous hydro- graphic basins. Our method of examining thoroughly the distribution of plants over a small hydrographic area, and connecting this with a similar work in a neighboring area, also limited by natural, not artificial, bound- aries, we believe to be thoroughly scientific. Moreover, we believe that induction based on collated evidence of this character will furnish the only conclusions in the future on the evolution of the floras of continental basins as we now find them, which will be acceptable to the scientific mind. The main facts of geographical distribution are within our reach, but the evolution of the present distribution, excepting in the case of islands or isolated mountains, is a question almost wholly unexplored. The affinities of a small flora are to some extent shown by the commonest wild plants and by the rarest. The former are present in related floras because inter-distributing has been easy and the conditions of soil and climate particularly favorable. Rare plants may occur for a variety of reasons ; but if it is because the region where we find them has so changed in the conditions favorable to their existence that they are being gradually exterminated, then indeed we have in them a pre- cious title-deed, without which we should not be in possession of a series of facts or suggestions, most valuable from the point of view of science. Again, if conditions exist in our region, allowing the rare occurence of plants which are common much farther north or south, while such spe- cies do not appear in contiguous regions, the exact nature of those con- ditions becomes interesting to us, and usually not difficult to ascertain. There is another method of determining the relationship of a small flora, however, which seems to us of more value than any other, although its successful and judicious application requires experience. If we find that a small number of species, of coast plants for example, extend to this region but no further west, while a greater number of southern spe- cies find their northern limit here, we conclude the flora has greater affinities with the South than with the Atlantic slope. If we find this INTRODUCTION. flora is the southern limit for many northern species, while it is the northern limit for fewer southern species, then some great northern basin or plateau has contributed, presumably, more to its population than the southern mountain or plain. Such a conclusion must be checked by reference to the affinities of the characteristic types present ; nevertheless, concerning the origin of a flora, we consider the test of limit-species a reasonable one, and indeed, from experience, the most critical single test we can apply. GENERAL RELATIONSHIPS. CHARACTERISTIC TYPES. We will now endeavor to make an appli- cation of these canons to our Lackawanna, Wyoming and Pocono Flora. The plants common in this region, but common also throughout the Appalachian region, such as the Rhododendron, the Chestnut-Oak, the Birches, the Witch Hazel, the sweet-scented fern, Dicksonia, we pass by as plants which can tell us nothing we do not know in respect to the affin- ities of a small flora. There are, however, certain species characteristic of the hillsides lining this valley, frequently appearing in large numbers, but which are not of universal occurrence in the Appalachian region. Such are the Wild Indigo, the Sheep Laurel, the Sweet-Fern (Myrica asplenifolia})\hz Sumach (Rhus copallina] ; and in certain places the Purple Hardhack (Spinca tomentosa] and Andromeda liguslrina are equally abundant. All of these are wanting or comparatively rare im- mediately outside the valley to the north or west. The above plants and others we might name are characteristic of, though not confined to, the drier region of the Atlantic slope, and their presence here is due, no doubt, largely to the character of the soil. RARE PLANTS. Of the rare plants of the Flora exclusive of the Po- cono, we might mention Linum sulcatum, Silene Pennsylvania, Phy- sostegia, Pedicularis lanceolata, Cunila, Polentilla arguta, A Ilium cer- nuum, Utricularia intermedia, U. cormita, and others, reported to be scarce in Pennsylvania, while the pretty Potentilla tridentafa, occurring on the summits of Penobscot Knob and Bald mountain, is known no- where else in the State. In passing to the Pocono this list would be greatly increased. Of these the only one we wish to speak of in this connection is the Little Mistletoe {Arceutkobium pusillum) parasitic on the limbs of the Black Spruce, discovered by the writer in 1886, and noted in his "Preliminary List" of this region. It is known in a few places in New York and New Hampshire, and nowhere south of our stations, which are the only ones yet discovered in Pennsylvania. INTRODUCTION. ALLEGHENIAN SPECIES. The Allegheny mountains, from their pe- culiar position, their densely wooded character, the amount of moisture condensing on them, are the home, especially in their southern section, of a large number of species peculiar to their slopes or summits. Our Flora also has its list of those which may be called Alleghenian, small in proportion to the less distinctive character and lower elevation of the Pennsylvanian ranges. We include the following in this list : Dicentra Exitnia, Aster concinmis. Ilex mollis, Calamagrostis Porteri. The following are also characteristically Alleghenian, although occa- sionally found in the mountains of New York and New England, or in districts allied to the Allegheny system : Ilex monticola,) Carex lurida % var. gracilis y Rhododendron maximum, Carex ccstivalis, Aspleniuni montanum. The only one of the nine plants mentioned which descends into the valley proper is the Rhododendron, which is less distinctively Alleghe- nian than the others. On the other hand, the earlier list of common plants mentioned, which give character to this region, and distinguish it from the districts adjoining north and west, are mostly plants of the valley or of the lower slopes of the mountains. SPECIAL AFFINITIES WITH LARGER FLORAS. Turning now to a consideration of those species which have their cen- ters of development in regions more or less remote from our valley and plateau, and which extend to this region, but no farther, we find facts of considerable interest. THE ATLANTIC SLOPE. There are a certain number of Atlantic slope species whose western limits of distribution are within our borders. We have noted the following : Lechea thymifolia, *Orontinm aquaticum, Solidago puberuhi) Calamagrostis Nuttallii^ Aster raduldj Lycopodium inundatum, var. Bigelovii. *The "Golden Club," Orontium aquaticum, growing in several of our ponds, deserves a passing notice, as it may have been introduced here by the Indians. Kalm ("Travels in Nor. America," II., p. 110-115) says its seeds are used as food by the Indians, who call it Taiv-kcc. Brinton ("Lenni Lenape and their Legends," p. 50) says "the Delaware Indians" (the former occupants of the Wyoming Valley and also of the Atlantic coast regions), "collected for food the seeds of the Golden Club, common in the pools along the Creeks." In their migrations back and forth they may have transplanted this food plant to the inland ponds. INTRODUCTION. SOUTHERN SPECIES. So far as we are able to learn the following southern and southwestern species extend no farther north or northwest (or but little farther), although a few extend along the coast into New York or New England : Arabis dentata, Betzda nigra, Dicentra eximia, Pinus inops, Silene Pennsylvania, Aletris farinosa. Ilex mollis, Melanthium latifolitim, Robinia Pseudacacia, Amianthium musca:toxicum, Helianthus parviflorus, Scleria paziciflora, Rhododendron canescens, Panicum agrostoides, Cunila Mariana, Triodia cuprea. The above divide themselves into two groups, the plants belonging to the valley and the plants belonging to the dry ridges of the mountains, corroborating the evidence we find from actual observation, of their ori- gin in a warmer region. We trace the beautiful River Birch up the branches of the Delaware, up the Susquehanna from its mouth to above the Wyoming Valley, but not certainly beyond Tunkhannock, and up the Lackawanna to Peckville. Like the dusky Pinus inops, its presence suggests the peculiar warmth of the south. Robinia was noticed more than a century ago by travellers crossing "Locust Ridge" on the Pocono. This, with Melanthium and Amianthium, two curious Liliacerc, are characteristic of the mountain group of the southern species. NORTHERN SPECIES. But our Flora is -connected with the north by a far greater number of peculiar species than with any other region. Above fifty-five northern species have been found which do not extend south of our territory. This number, moreover, does not include those species recognized as northern, but which extend through this section, along the Alleghenies to North Carolina or Georgia. Twenty of the fifty-five belong to the Heaths and the Sedges. The Rhodora, the Pale Laurel, the Labrador Tea, the Small Cranberry, the Cotton Sedge, all particu- larly attractive plants, belong to these two orders. Nearly all these northern forms are confined to the mountains, and in the case of those found in the valley, as well such as Portentilla palustris, I sus- pect they will ultimately be discovered much further south, where they have retreated wholly to the mountains. WESTERN SPECIES. Turning to the west, I have been able to find but two western species extending eastward only to our limils, a garlic, Allium ccrnuum, and a grass, Kccleria cristata. xii INTRODUCTION. CONCLUSIONS. Comparing this Flora with the Cayuga Flora, and enumerating the species whose distribution terminates in each, we have tabulated the following facts : Northern. Southern and S.W. Western and S.W. Atlantic Slope. Cayuga Flora 16 14 16 3 Lackawanna and Wyoming Flora 55 17 2 6 These figures are of course not absolutely correct, and cannot be until our Flora is more fully studied and distribution in general is more accu- rately known, but they are relatively so. While the Cayuga is most closely related to the territory which in- cludes the Ohio Valley and the southern shores of several of the Great Lakes, it has a considerable affinity for the North and Northwest and but little for the Coast. The Lackawanna and Wyoming Flora, includ- ing the Pocono Plateau, shows a strong relationship with the North, next with the South, and really a decided affinity (although not exhib- ited by a large number of peculiar species) with the coast. Indeed, the similarity in aspect between the vegetation of this region and that of the Connecticut coast is striking. Excluding the Pocono, its relationship is largely with the South, next with the Atlantic slope, while that with the North is scarcely discoverable. The cause of the relation of the Pocono table -land flora with the northern lies not so much in the height as in the breadth of the plateau, and the density and coolness of the original forests clothing it. I have perused a considerable number of journals of army officers, travelers, naturalists and missionaries, who traversed the Pocono more than a cen- tury ago, when it was threaded only by two slender trails traced by Ihe children of the forest. It was then known as the ' 'Great Swamp." On it were vast tracts of forest, tangled, wet, dark and gloomy. Col. Dear- born, writing in 1779, says after passing the Pocono Knob he entered what is called the Great Swamp, containing trees of pine, spruce, hem- lock and maple of amazing size. This includes a dark, dismal portion, between Locust Hill and the head of Laurel Run, known as the "Shades of Death." Rev. Wm. Rogers refers also to the great height of the pines (White Pine), ascending 150 feet before reaching limbs. The abundance of the larger "Lawrel" is also commented on. There is abundant testimony showing that this was a heavily forested tract orig- inally. Now, great areas of barrens greet the eye, where alders, dwarf INTRODUCTION. oaks, red cherry, raspberry, brake and bristly sarsaparilla have take the place of the original forests on lands desolated by the lumberman's axe and by fire. There are portions of the pristine "Evergreen Woods" still left, or but just disappearing. The dark, dense Spruce woods about Lehigh Pond is an instance. Here we still find the Lady Slipper and Orchis undisturbed, and see how the Rhododendron, when in flower, lighted up the gloom of the forest primeval when the earliest travelers crossed the Pocono. This is indeed a natural forest region, and the removal of the woods only demonstrates more clearly, what one of the earliest observers asserted, viz : the utter uselessness of a large portion for either pasture or cultivation. Every consideration of economy, public good, and even private wealth, demand that these regions be reforested. If woods again cover this table-land they will hold back, by means of the spongy soil they accu- mulate, the surplus freshet waters from the hundred torrents and moun- tain-brooks which supply pure water to the great coal-valley cities, and which ought to keep up through the long drouths the volume of the Le- high, Lackawanna, and the brooks flowing into the Delaware. Further- more, the pine, hemlock, spruce and cherry which once grew here to "amazing size," may be again grown through planting, as they are in the mountains of Europe, and made a source of future wealth. LOCAL NAMES. In Ileckwelder's History of the Indian Nations, Brinton's Lenni Lenape, the works of Peter Kalm, David Zeisberger, George Henry Loskill, Clark, Hale, and others, the meaning given of a number of the Delaware names applied to our region has interested me. I give a few notes on the important ones. Susquehanna : the latter part of river names among the Delawares, viz., hanna, hanni or hannock, means a "flowing stream" ; and Heck- welder says Susquehanna means a "straight stream," referring to its course near the mouth. Lackawanna {Lechau-hanneck), "the fork of the river," referring to the junction of this with the Susquehanna. Lehigh (Lechau\ the same as the preceding, meaning here the fork or branch of the Delaware. Tobyhanna (Topi-hanneck), the "alder stream." Timkhannock) the "small stream." Wyoming, the "great plains." Moosic, origin not known to me. It is near a word in one of the Del- xiv INTRODUCTION. aware dialects meaning "marsh" or "swamp." The English name, the "Great Swamp," may have been derived from the Indian name, the localities being practically identical. Pocono, the origin unknown to me. On old maps Pocono creek is called Pocono-hanni. The meaning of this, viz., the "stream dividing" the hills, is very appropriate, as this creek occupies a broad recession on the eastern side of the plateau. Possibly the name may have been trans- ferred by the English settlers to the mountain. Nanticoke, the "tide water people," the name of a tribe settling in the valley, but originally from Maryland.
