THE SCHOOL FERIST- FLORA

OF CANADA.

Comprising Descriptions of all Ferns known to Inhabit the Dominion,
Together with an Account of their Geographical Range or
Prevalence in the Several Provinces, and Special Localities
for the Rarer Species.

BY PROF. GEORGE LAWSON.

FERNS I THEIR BENERAL CHARACTER ; THEIR PARTS OR ORBANS ;
CLASSIFICATION OF THE CANADIAN FERNS.

The Ferns form a very natural and distinct group of plants. They are
familiar to all observers of natural objects from tlie beauty of their ample
foliage, which is most commonly plutnu-iike in form, of a fresh and vivid
green hue, and much divided or cut into small leaflets or lobes; these, on close
observation, are seen to be marked on the surface, or lightly sculptured or
embossed, with delicate veining.

The Ferns are called Cryptoijamous (flovrerless or hidden-flowered) plants,
because flowers proper, consisting of petals and other showy parts, are hero
absent. They are also called Acrogens (summit growers), on account of a
peculiarity in the mode of growth of their stems, which do not increase, as in
hardwood trees, by annual layers of wood, or, as in the pdm-stem, by
descending, interlacing, fibrous bundles, but only by successive additions at
the top end or apex.

FERN -FLORA OF CANADA.

The Parts or Organs of the Fern.

The Fern Plant is formed of parts or Organs that are very different, both in
nature ajid appearance, from the parts that we see in ordinary Flowering Plants.
In order to understand the descriptions of the different species, we need to know
the terms that are used to denote the several parts of the plant. There are no
\iToper flow firs on the Fern Plant, so that we do not apply that term, or any of
the terms used to describe the parts of flowers, to any part of a fern ; but the
fern bears a graiudar substance, which takes the place of flowers and seed, and
words (or scientific terms) are used to express its nature and parts, just as names
are given to the parts of the flower. Ferns, to the ordinary observer, seem to
have leaves, and these are usually green and flat and more or less divided, like
many true leaves, but they are not merely leaves ; they are also the fruit or seed-
bearers, and the botanist calls them Fromh.

The Fern Stem or Rhizome.

As to the part that cdnstitutes the true Stem in ferns, some explanation may
be required, especially by those who have been accustomed to see Tree Ferns of
warm and equitable climates free from winter frosts, (such tree ferns may be
seen in the conservatories of public gardens). In the Tree Fern, the stem rises,
erect and tree-like, into the air, clothed below with the remnants or stubs of
old decayed fronds, these stubs being themselves invested more or less completely
with the fiexuous, hard and black root fibres, which, originating from the stem
itself, are insinuated among the old stubs. From the summit of this stem or
trunk of the tree fern, there is a radiating, widely-spreading expanse of delicately
divided fronds, drooping gracefully towards their tips, — the whole presenting a
striking object of beauty. The organ thus developed into an erect stem in tree
ferns is called the Caudex.

Among our native Canadian ferns we have one imperfect example of this erect
eaudex-growth in the first fern to be described, the Ostrich Plume Fern, a
species probably very ancient in origin, but which still exists in two apparently
distinct varieties, one confined to Europe, the other to America. While the
Ostrich Plume Fern has an erect bulb-like corm, producing from its apex a circle
of magnificent, erect, plume-like fronds, thus simulating the tree fern, (the

the

Ihe

European plant, as seen in Botanic Gardens, having apparently a more elongated
and elevated eorni than ours), yet this conn differs from the true ai-rial stem of
tree ferns, not only in its partially subterranean character, slight elongation, and
limited endurance, but also in sending forth radiating horizontal runners, ending
in buds or young corms, which become new plants, thus giving a lateral mode
of propagation or increase. We have no true tree ferns in Canada to whose stems
the term caudex can be properly applied, and in describing uur Ferns this part
is called the Rhizome.

Different kinds of Rhizomes.

In our Canadian ferns the stem is usually prostrate, often underground, or at
the surface and covered by moss cr herbage, or hid in the crevices of rocks, the
anterior or growing extremity only, with its fronds and crown of frond buds,
assuming the erect position. Such stems resemble the underground creeping root-
like stems of flowering plants, and are thus called liJiizomes. The rhizome differs
very much in form and size in the different genera of Ferns : —

In many ferns the rhizome is stout, produces root fibres principally at the
older or posterior end, and is abundantly covered with the persistent stalk-romnants
or stubs of the decayed fronds of former years.

In the Common Polypody the rhizome is elongated, rather thick, fleshy, and
creeping on rocks, trees, or other solid surfaces, without persistent stipe-stubs,
the stipes or stalks finally becoming completely separated from the rhizome by a
joint or articulation, as in ordinary deciduous leaves.

In a third class of ferns the rhizome is very slender, cord or wire-like, creep-
ing underground, often much branched, not forming bud-crowns, and consequently
not producing circular tufts of fronds, but sending them up singly at intervals
along its course. When the fronds decay they do not leave the lower parts
of the stalks behind as permanent stipe-stubs.

The rhizome is a part of great importance, often presenting characters whereby
different ferns may be clearly distinguished from each other, but superficial
observers are apt to neglect it, and to be contented, in collecting specimens for
examination or preservation, with the mere fronds seen above ground, which,
when studied alone, are in many cases puzzling, fram the tendency to mimicry of
form so often found in plants that are really distinct.

TIE FERN FROND; ITS FARTS; THE STIPE OR STALK; THE
LAMINA OR LEAFT PORTION ; DIVISION AND GUTTING OF THE
LAMINA ; FRUIT DOTS ; THE RAGHIS ; YEINING,

From the indications giv(.Mi, it will he soon thut tho principal Orj^nna of our
fern plants are : (1) tht; (mostly) horizontal Wn'zome, with its, often wiry,
tortuous, descending rootfihres, produced not only from its posterior extremity,
but often also emergent along its course from the matting of more or less
decayed stipe-stubs ; (2) the FnnKf, or le.if, which, as in ordinary leaves, consists
of two parts, — the Stipe or stalk (corresponding to the petiole of flowering plants),
and the Lamina or leafy portion, which, in a few cases is simple or undivided,
but in most ferns is much divided, and in various ways in the different groups.

The Lamina. — The Lamina may be more or less deeply cut or cleft from the
margins towards the Rachis or midrib, when it is said to be Pinnatijid. When
the clefts are complete so as to reach the rachis, and divide the lamina into separate
leaflets, arranged feather-like in pairs or alternately, on either side of the rachis,
the lamina is said to be Pinttaff, and tho leaflets are termed Pinnoi. These
pinnaB may be again divided in a similar manner, into distinct divisions or leaflets
along either side of a Secomfari/ Rathia, and such divisions or leaflets are called
Pinnules, the lamina thus becoming Bi pinnate. The pinnules may themselves be
partially cut into lobes so as to be pinnatifld, or even completely divided into per-
fect leaflets, and then the frond becomes Tripinnate. These differences are
important in distinguishing the several species ; but it is to be observed that the
extent of division of parts is less perfect in young and stunted forms, and more
complete in those that are mature and luxuriant, — so that in a species normally
bipinnate, a young or starved frond may be only pinnate with pinnatifid divisions,
while an old or luxuriant one may be bipinnate with pinnatifld divisions, or even
tripinnate. Such cases occur in the Lady Fern and tho Buckler Fern.

Fruit Dots — In many ferns the lower surface of the frond has fruit dots,
which are most abundant on the upper half of the frond, but, in certain species,
there are separate fertile and infertile fronds, the fertile ones being usually nar-
rower in their parts or altogether contracted and unleafy.

The Rachis, and its side Branches or Rachides ; Veins ; Veinules ;

Veinlets.

As the continuation of the Stip^ into a divided or compound frond-lamina is
called the Ilachis, and its side hrauchca Sermufari/ liachiiles, so, when the lamina is
simple or undivided, the midvein (in that case also a continuation of the stipe) is
called the Casta or midrib. The ditFerent modes in which the veins, forming the
framework of the leafy portion of the fron<l, are disposed afford useful characters in
the discrimination of speci»!S ; the branches from the costa are termed Veins ; the
branches from these veins are called Veinule.% and the branches of the veinules,
Vf.hiletsi. In like manner, whatever may be the extent of division of a frond
into pinnae or lobes, the Veins are the Hrst series of branches from the midrib or
costa (whether of the frond whon simple, or of its separate ultimate divisions, or
leaflets, when compound). Veins are the primary branches from the costa, Veinules
the secondary, and Veinlets the tertiary series. Where there is no prominent costa,
the ribs arising directly from the base of the leaflet are called veins. The part
of the vein on which the fruit dot or Sorus is seated, is called the Iteceptaele.

The parts described may all be seen, more or less distinctly, by the naked
eye, but, in examining the veining of the fronds, the sorus or fruit dot, and its
protecting indusium, a simple lens or magnifying glass of any kind will give
great help.

The Sorus, or Fruit Dot. — The sorus (plural sori) will be seen to consist of
numerous visor-shaped, usually stalked, pouches, called Spore-Cases^ each filled with
an exceedingly fine dust; the individual particles of this dust, called Spores, are too
minute to be visible even to the keenest human eye, without a lens, yet it is these
tiny particles that give rise (as if they were buds or seeds) to new individual plants.
Th« remarkable processes attending the growth and development of these invisible
specks into fern plants can only be followed by use of the compound microscope.

The Indusium. — In some ferns (as the common polypody and the oak fern)
the sori are simply round granular dots of spore cases, without any protective
covering ; in many others, the little clusters of spore cases are enveloped or
sheathed at first in a delicate, colourless, scale-like membrane, or are surmounted
by a small disc or shield-like covering. This protecting organ, which falls away
as the spore cases mature and drop their spores, is called the Indusium.

FERN -FLORA OF CANADA.

THE SPECIES OF FERNS j THEIR ARRANSEMENT OR CLASSIFICA-
TION INTO GENERA; THEIR BENERIC AND SPECIFIC NAMES.

Gknera and Speciks. — Tlie species of ferns are classified into Genera^ and
each genus lias its generic name ; it is usual to illustrate this l)y comparing a genua
to a family of peoi)le, each (re.nun of plants being known hy its generic name
just as cftcli family is known by the ancestral name. In like manner, as the
full name of a person is formed by uniting the indivdual or given name with the
ancestral family name, so the full name of the kind or species of fern is formed by
writing together the generic and specific names, as Pnlypoilium vnhinre, in which
Poh/pofUin/i is the generic, and vnljare the sjiecific name, This comparison of
the names of species and genera of plants to the individual and family names of
people is correct merely so far as it is an example of the mode adopted in naming
things and animals and people ; it must not be supposed that the analogy or com-
parison can be carried further, for a person is not a species, but only one of a
great many individuals, who, taken together, form the human race, the species.
It is equally true tliat a family, a number of related individuals, can only be
likened in a distant way to a tjenus. More correct comparisons may be made with
the lower animals. The dog and jackal and wolf arc all difFerent, and easily
known from each other, they are all separate species, and those who study ani-
mals — zoologists — give to each a sptrijie name, just as botanists do with their
plants. But the dog and jackal and wolf are in many ways alike, — in the forma
of their bodies, their teeth, their food, their habit of running in packs, and so
on, — and a zoologist may class them all together into one genus, and give to that
genus the generic name Canis. So with our Ferns. All the delicate Bladder
Ferns are known by the generic name Cystoptens ; the family of Spleenworts is
known as Aspleniiim ; the Shield Ferns, with hard glistening spiny-edged fronds,
and orbicular strong shield-like indusia or coverings to their fruit dots, are styled
Polystichum ; and the species of Buckler Ferns, with duller foliage and thinner
kidney-shaped indusia, are called Lastrea. The separate species in a genus have
each a Specific name or terra added to the generic one, just as human individuals,
members of the same family, have different christian names, and, as we have
seen, the two names or terms so united form the complete name of the particular

FERN- FLORA OF CANADA.

227

species of plant. Thus: Ctj>*iopteru frinjilis is the name applied to nil the
inilividuals (themselves un«li.stinf^uishahlo from ench other) of this particular
species of plant, — Cijstopteris heing the generic, frmjilis the specific, term.

Vakikties. — All the inilividuals of a species are not exactly alike, however,
either in plants or animals. We know that in the human species the people of
difFeront parts of the earth are in some respects dift't-rent from each other.
Although all dogs are of one species, yet there are many kinds of dogs that oro
easily recognized from each other, such as terriers, hounds, and spaniels, and tliese
are classified and naiufd as varieties. It is exactly the same in the case of ferna
and other plants. The last species montioneil, C[/xfopf''rin/rat/il /'.'<, fringes the sea-
shores and islands and the rocky h.mks of our lakes and streams, and varies in
size, and in the form and division of its fronds, in difFerent situations ; but this
si)ecies also extends over a large portion of the globe, being e(|Uidly at home on
the Greenland and Labrador shores, in gulches on the highest snowy peaks of
Colorado, on winterless islands like Madeira, in Mexico, various parts of South
America, Australia, Africa and Asia. It is to be expected that this little wan-
derer will vary in appearance, dwarfing where it meets witii lack of heat or
moisture, liecoming almost an evergreen where it has no severe winter to contend
with, swelling out to large size and becominj; of soh juicy tixture where it
grows in a mild saturated atmosphere. In such ways, Varh.tics are produced, and
when these varieties appear to be sufficiently constant, and not the mere result
of temporary surroumlings, names are given to distinguish them. The name of
the variety has to be added to the names of the genus and species, and thus it
comes that some of the ferns have three, instead of two, names.

How the diflferent Genera of Perns are known.

The most precise distinctions between the different genera are found (1) in the
nature and branching of the minute veins in the divisions of the fronds, — whether
they form a connected net-work or are spread out, simple or forked, like a fringe ;
(2) in the position of the fruit dots (called Snri) on the frond, and whether the Sori
are separate from the veins or connected with them at their points, or sides ; (3)
in the al)sence or presence of a special involucre or general covering for the sori or
masses of spore cases, formed by the incurving of the frond-margin ; and (4) in the

character, when itreseiit, of tlio delicate im'rnl)rnne or scale-like body called the
Indusiuw, which covers and protects the SoniM until the spore-cases are matured.
The Table of Generic Characters, and fi^^'ures of portions of fronds showing

time to time, with the descriptions given of the genera and species. The Pupils may then be directed to
search, in suitable localities in the woods, for the particular species. Having collected their plants, they
should be allowed to compare these fresh -gathered specimens with the dried specimens in the School Collec-
tion, and with the descriptions in the book, so as to ascertain how far they agree, or are different. The great
object should be to avoid all puzzling, and lead to pleasant and intelligent enquiry into points of corres-
pondence and difference.

Widely distributed all over Canada, but only on shady, rocky banks or hillsides, and
chiefly where the air is kept moist by neighbouring lakes, rivers, or the sea. Var.
Mackayii is a common form in Nova Scotia. The name of the genus is derived from the
texture and form of the indusium, which is like a minute inflated bag or bladder.

the apex on the under surface ; pinnjv oblong-lanceolate, narrowed at the tips ; pinnules
oblong, obtuse, incisely toothed ; sori small, usually not very numerous ; indusium short.
This species produces fronds of two forms, — the one being broad at base and comparatively
short, with horizontal pinnaj, while the other kind is narrow and drawn out to a great
length (six or seven times longer than broad) and with less horizontal pinnaj.

pinnte stalked, linear lanceolate, except the lowest, which are much broader at the base,
and triangular or deltoid in outline ; pinnules oblong or ovate-lanceolate, acute, the largest
an inch long by half an inch broad, pinnatifidly cut, or incised, into small, aristatcly
toothed lobes, (that is each lobe ends in a fine bristle point) ; posterior basal pinnules of
the lower pinnse much larger than the anterior ones. Sori small, arising from the side
veinlets, and thus appearing between the midrib and margin of the pinnules ; indusium
smooth or occasionally glandular (this is best seen when the frond is newly developed).
In autumn the erect stipes begin to weaken and decay at a point within an inch or two
of the base, allowing the fronds to fall upon the ground. Still undetached completely
from the rhizome, they lie under the snow over winter and are finally withered up by
the drought of the following summer, forming a matting around the growing plant ;
thus the species is usually described as imperfectly evergreen. There are many variations
of this species, in every country in which it occurs, that can with difficulty be distin-
guished from each other. The American form, which mostly prevails in Canada (our
common wood fern), is kuown as var. intermedia.

Var. DILATATA has a stouter rhizome, shorter stipes, broader lamina, which is ovate,
sub-triangular or oblong-lanceolate ; the basal scales are larger, more abundant, and
extend further up the stipe, and some of the larger scales have a very dark stripe or
blotch in the centre ; indusium rsually (but not always) fringed with stalked glands.

Common in woods and shady places. 0«<aWo .—Abundant in the woods about
Kingston, as Collins's Bay, &c. ; Smith's Fall's; Odessa; Falls of Niagara; Hinchin-
brook ; Gananoque Lakes; Farmersville; Hardwood Creek; Delta; Upper Ridcau

throughout Ontario ; it is the common wood fern. Qurfwc, Neio Brnnmcick, Nova Scotia :
— Common in the woods, especially in sea-shore districts. Around the wooded shores of
Nova Scotia, as at Blomidon, Canso, Whycocomagh, i'arrsborough, &c., this fern
attains a great si7.e, the fronds rising to a height of three or four feet. Neir/oumllanU : —
Probably common, although only noticed in a few localities; Langlade; Micjuelon. The
variety ditatata is found at the Joggius, near the mouth of the Bay of Fundy ; also in
Newfoundland.

3. L. CRIST ATA, J'resl. Crented Buckler Fern, — Rhizome short, stoutish, branched,
with scaly adherent stipe stubs. Fronds erect rigid, in tufts, from 1 to 3 feet high
(the infertile ones shorter and less erect). Stipes stout, half as long as the lamina, with
few scales upwards. Lamina linear-oblong or lanceolate in outline, rather light green,
pinnate or bipinnate ; pinntv numerous, the lower ones apart, short, triangular ; pinnules or
segments of pinnte mostly adnate (connected at the base), posterior basal pinnules scarcely
longer than the anterior ones, oblong, blunt, more or less pinnatitid or incised and
serrate, the serraturcs tipped by spinulose points ; veins of lobes Hexuous, depressed or
etched on the upper surface. Sori large, with persistent induaia, numerous, principally
on the upper half of the frond, forming a row on each side of the midrib of tbe lobe,
and nearer to midrib than margin.

Swamps, swales and boggy ground, in shelter of trees or bushes, not rare. When
swamps are cleared of trees, this fern soon disappears. Ontario : — Swampy places
in woods around Kingston ; Belleville ; Ramsay ; Prescott ; Toronto ; London ; &c.
Quebec : — Ottawa and Gatineau Rivers ; Three Rivers ; Lake of Three Mountains ;
Gaspe ; St. Ferreol, &c. New Brunswick : — General throughout the province, but not
very common. Nova Scotia : — Common in shaded, swampy grounds in Halifax County ;

4. L. BooTTii, Lawson. Dr. Boott'a Buckler Fern. — This is supposed to be a
hybird fern, and is intermediate in characters between L. cri^tata and L. spiiiulosa, —
diflfering from the first in its thinner fronds with more acute pinnules, larger teeth,
the posterior basal pinnules being larger than the anterior. From the second named
species, it differs in producing in spring, early, small, spreading, ban en fronds which are
pinnate, with decurrent oblong-obtuse pinnules, like those of L. cri^tata ; and later, or
summer fronds, frequently fertile, which are erect, and larger, with decurrent oblong-
obtuse pinnules, as in the earlier barren fronds.

Very rare, and scarce where found. Damp ground near the Sackville River at
Bellahill, Halifax County, a small patch, growing with L. cristata and L. spinulosa,
found by the late Mr. Peter Jack.

chaffy ; lamina rather broadly lanceolate, imperfectly or completely bipinnate ; pinnules
obU.ng, obtuse or aciitisli, serrate, crenate, or iucisely lol)ate, the basal ones more or
less distinct, the upper confluent (united or running into each other), marginal serraturea
not spinulose. Sori numerous, nearer midvein than margin, usually confined to the lower
or basal luilf of the pinnules ; indusium firm, roundish, convex at first, with a no*" 'h at
its depressed funneled point of attachment to the veinlet.

Rare, and local in its distribution. This species was not definitely known to be a
native of Canada, until discovered on Owen Sound by the late Mrs. Roy, of Royston
Park, in 18GU, soon after which it was found in otiier districts by several botanists.

fourteen inches in length, thin and pale green, lanceolate, pinnate, remarkably narrowed
below, the pinnae gradually smaller from above the middle of the frond downwards until
they become mere auricles at the base close to the ground ; pinnae sessile linear or linear-
lanceolate, acuminate, more or less approximate, deeply pinnatifid ; pinnules oblong,
usually flat, veins simple (not forked nor otherwise branched); sori small, almost marginal,,

Nova Scotia : — Found on the shore of Grand Lake, twenty-three miles from Halifax
city, N. S., in August, 1879, by Miss Elizabeth G. Knight, of New York. The plants
were less than two inches high, the fruit immature ; they were growing among the
rhizomes of the royal fern. This little fern has not been found since at that place, nor

world for this species is in New Jersey, where it is also very scarce. Plants that are
very rare now, and circumscribed in area, are believed to have been more prevalent at
sorrie former period.

This unobtrusive fern, so small in size, so inconspicuous in form and colour, belongs

few species are now widely scattered on the islands and around the shores of tropical
regions of the earth. It may be regarded as one of the remnants of a probable, long lost,
Atlantis flora, and is hence called the Atlantis Fern.

(iENUS XXIV.— BotryChlum, Swartz. Grape Ferns. Moonwort.

1. B. ViRQiNlANUM, Swartz. The Virginian Grapp- Fern or Moonwort. — Root fibres
few, thick, fleshy ; stipe fleshy, swollen at base, with a longitudinal sheathing fissure
showing the enclosed hairy frond-bud. (In all the other species the bud is entirely
concealed by the base of the stipe.) Lainina, infertile, branching from the main axis
about its middle, sessile, but its three primary divisions stalked, broadly triangular in
outline, much divided, each of the primary divisions being once, twice or three times
pinnatifld ; the lobes of the pinnules oblong-ovate, deeply incised ; texture of the lamina
thin, delicate, membranous, veiny. The stipe, rising as a main axis above the lamina,
ends in a compound fertile spike of yellow sporangia, beinjj bipinnate or tripinnate. Plant
very variable in size, usually a foot or more in height, and one of the moat beautiful and
distinct of our Canadian ferns ; dwarfed specimens, only a few inches in length, are
not rare.

In rich M'oods, or in rocky places where there is accumulation of vegetable soil,
gensral, but nowhere abundant. Ontario : — Not uncommon in the woods about Kingston,
and the surrounding country, as near Odessa ; Wolfe Island ; also Hinchinbrook, Ac. ;

0. VULOATtM, Linn. Addn-'s Towjiu.—Vihuome fleshy, with a descending axis,
spreading fleshy roots, and a sheathed terminal bud or growing point. Frond a few inches
in height ; stipe erect, succulent, hollow, bearing a sessile leaf-like frond, subtending the
erect fertile peduncle which bears the fleshy spore cases imbedded in aseiies or row on
each margin of the siiike ; they ultimately split horizontally and give it a toothed appear-
ance. Somttimes the fruit-spike is forked, and it is so figured in very old books. This
probably originated the name Uphioglossum, or Adder's Tongue.
