PREFACE.
The first edition of Gray's Manual was published in 1848. It was to a
great extent rewritten and its range extended in 1856, and it was again
largely rewritten in 1867. The great advances that have since been made
in systematic botany and in the knowledge of our flora have for several
years past made another revision desirable, which Dr. Gray before his
death was purposing to undertake.
The present editors, acting to the best of their ability in his stead,
have endeavored throughout to follow his methods and views. The original
plan, so long retained by Dr. Gray and so generally approved, has been
closely adhered to, the characters and descriptions of the last edition
have been left essentially unchanged so far as possible, and in the
numerous alterations and additions that have been considered necessary
or advisable, his conclusions and principles have governed in every
matter of importance, so far as they could be known. The effort
especially has been to maintain that high standard of excellence which
has always made the Manual an authority among botanists.
In the treatment of the genera and species, Gray's Synoptical Flora has
been made the basis in the revision of the Gamopetalous Orders, and the
manuscript in continuation of that work, so far as prepared, for the
Polypetalous Orders which precede _Leguminosæ_ (excepting _Nuphar_, the
_Cruciferæ, Caryophyllaceæ, Vitis_, and the small Orders numbered 18,
22, 23, 25--27, and 29). The genus _Salix_ has been rewritten for this
edition by M. S. BEBB, Esq., the genus _Carex_ by Prof. L. H. BAILEY,
and the Ferns and allied orders by Prof. D. C. EATON. For the rest, all
known available sources of information have been made use of, and much
willing help has been received from botanists in all parts of our
territory.
The increasing interest that is taken in the study of the Cellular
Cryptogams, and the desire to encourage it, have led to the inclusion
again of the Hepaticæ, which were omitted in the last edition. These
have been prepared through the kindness of Prof. L. M. UNDERWOOD, though
the limits of the volume have necessitated somewhat briefer descriptions
than he considered desirable. The three fine plates illustrating the
genera of these Orders, which were used in the early editions, are also
added, with a supplementary one, as well as an additional one in
illustration of the Grasses, thus increasing the number of plates to
twenty-five. A Glossary of botanical terms is appended, to meet an
expressed need of those who use the Manual alone, and a Synopsis of the
Orders in their sequence is given, to contrast more clearly their
characters, and to show the general principles which have determined
their present arrangement. This should be a useful adjunct to the more
artificially arranged Analytical Key.
GEOGRAPHICAL LIMITS, AND DISTRIBUTION.--The southern limit of the
territory covered by the present work is the same as in the later
previous editions, viz. the southern boundary of Virginia and Kentucky.
This coincides better than any other geographical line with the natural
division between the cooler-temperate and the warm-temperate vegetation
of the Atlantic States. The rapid increase of population west of the
Mississippi River, and the growing need of a Manual covering the flora
of that section, have seemed a sufficient reason for the extension of
the limits of the work westward to the 100th meridian, thus connecting
with the _Manual of the Flora of the Rocky Mountain Region_ by Prof.
Coulter. These limits, as well as that upon the north, have been in
general strictly observed, very few species being admitted that are not
known with some degree of certainty to occur within them. The extreme
western flora is no doubt imperfectly represented.
The distribution of the individual species is indicated somewhat more
definitely than heretofore in many cases, so far as it could be
satisfactorily ascertained. The extralimital range is also sometimes
given, but the terms "northward," "southward," and "westward" are more
frequently employed, signifying an indefinite range in those directions
beyond the limits of the Manual. Where no definite habitat is specified,
the species may be understood as found more or less generally throughout
the whole area, or at least to near the western limits.
NOMENCLATURE, ACCENTUATION OF NAMES, etc.--In case of question
respecting the proper name to be adopted for any species, Dr. Gray's
known and expressed views have been followed, it is believed, throughout
the work. While reasonable regard has been paid to the claims of
priority, the purpose has been to avoid unnecessary changes, in the
belief that such changes are in most cases an unmitigated evil. Synonyms
are rarely given except where changes have been made. As a guide to
correct pronunciation, the long sound of the accented vowel (modified
often in personal names) is indicated, as heretofore, by the grave
accent (`), and the short sound by the acute (´). In regard to the
derivations of generic names, many valuable suggestions have been due to
W. R. Gerard, Esq., of New York.
PROMINENT CHARACTERS are indicated by the use of _Italic type_ for the
leading distinctions of the Orders, and generally in the specific
descriptions for those points by which two or more nearly allied species
may be most readily distinguished. The ready discrimination of the
genera is provided for by a Synopsis of their leading characters under
each order. Whenever a genus comprises several species, pains have been
taken to render important differences conspicuous by proper grouping,
and when needed by a series of subordinate divisions and subdivisions.
The headings of these various groups are to be considered as belonging
to and forming a part of the specific characters of the several species
under them,--a fact which the student should always bear in mind.
ARRANGEMENT OF THE ORDERS.--The Natural Orders are disposed in very
close accordance with the method followed by Bentham and Hooker in the
_Genera Plantarum_, the principles of which are concisely shown in the
Synopsis of Orders which precedes the Analytical Key. The _Gymnospermæ_
are retained as a Subclass following the Angiospermous Dicotyledons,
with which they have an obvious relationship, in preference to placing
them, as some authorities would do, next before the Pteridophytes, to
which their affinity, if no less certain, is nevertheless obscure. A
more natural arrangement than either would be the withdrawal of the
Endogens, placing them at the beginning, in perhaps an inverse order.
ANALYTICAL KEY TO THE ORDERS.--As stated in Dr. Gray's Preface to the
last edition, this is designed to enable the student to refer readily to
its proper Order any of our plants, upon taking the pains to ascertain
the structure of its flowers, and sometimes of the fruit, and by
following out a series of easy steps in the analysis. It is founded upon
the most obvious distinctions which will answer the purpose, and is so
contrived as to provide for all or nearly all exceptional instances and
variant cases. Referring to the Order which the Key leads him to, the
student will find its most distinctive points brought together and
printed in Italics in the first sentence of the ordinal description, and
thus can verify his results. The Synopsis which follows will then lead
him to the genus, to be verified in turn by the full generic description
in its place; and the progress thence to the species is facilitated,
when there are several to choose from, by the arrangement under
divisions and subdivisions, as already explained.
It will be seen that the Key directs the inquirer to ascertain, first,
the Class of the plant under consideration,--which, even without the
seeds, is revealed at once by the plan of the stem, as seen in a
cross-section, and usually by the veining of the leaves, and is commonly
confirmed by the numerical plan of the flower;--then, if of the first
Class, the Subclass is at once determined by the pistil, whether of the
ordinary kind, or an open scale bearing naked ovules. If the former,
then the choice between the three Divisions is determined by the
presence or absence of the petals, and whether separate or united. Each
Division is subdivided by equally obvious characters, and, finally, a
series of successively subordinated propositions,--each set more
indented upon the page than the preceding,--leads to the name of the
Order sought for, followed by the number of the page upon which it is
described in the body of the work.
The book is now submitted to those for whose benefit it has been
prepared, in the trust that its shortcomings will meet with friendly
indulgence, and with the earnest request that information be kindly
given of any corrections or additions that may appear to be necessary.

SIGNS USED IN THIS WORK.
°, ´,´´ . The sign of degrees (°) is used for feet; of minutes (´), for
inches; of seconds (´´), for lines,--the line being the twelfth part of
an inch, and very nearly equivalent to two millimetres.
µ. In microscopic measurements, the conventional sign for the
micromillimetre or the one-thousandth part of a millimetre = one
two-thousandth part of a line.
♂ Bearing only stamens or antheridia.
♀ Pistillate or bearing archegonia.
? A mark of doubt.
! A mark of affirmation or authentication.
Figures or words separated by a short dash (--) indicate the extremes of
variation, as "5--10´´ long, few--many-flowered," i.e. varying from 5 to
10 lines in length, and with from few to many flowers.

Polypetalous Orders are destitute of petals, or have them more or less
united.)
ORDER 1. RANUNCULÀCEÆ. (CROWFOOT FAMILY.)
_Herbs or some woody plants, with a colorless and usually acrid juice,

separating across into 1-seeded joints (_lomentaceous_). Seeds
campylotropous, without albumen, filled by the large embryo, which is
curved or folded in various ways: i.e. the _cotyledons accumbent_, viz.,

ORDER 47. FICOÍDEÆ.
A miscellaneous group, _chiefly of fleshy or succulent plants, with
mostly opposite leaves and no stipules_. Differing from Caryophyllaceæ
and Portulacaceæ by having the ovary and capsule 2--several-celled, and
the stamens and petals sometimes numerous, as in Cactaceæ (but the
latter wanting in most of the genera), seeds, as in all these orders,
with the slender embryo curved about mealy albumen. Our genera are
apetalous and with the calyx free from the ovary.
1. Sesuvium. Calyx-lobes 5, petaloid. Stamens 5--60. Capsule
circumscissile. Succulent.
2. Mollugo. Sepals 5. Stamens 3 or 5. Capsule 3-valved. Not succulent.
1. SESÙVIUM, L. SEA PURSLANE.
Calyx 5-parted, purplish inside, persistent, free. Petals none. Stamens
5--60, inserted on the calyx. Styles 3--5, separate. Pod 3--5-celled,
many-seeded, circumscissile, the upper part falling off as a
lid.--Usually prostrate maritime herbs, with succulent stems, opposite
leaves, and axillary or terminal flowers. (An unexplained name.)
1. S. pentándrum, Ell. Annual, procumbent or sometimes erect; leaves
oblong- to obovate-spatulate, obtuse; flowers sessile, stamens 5. (S.
Portulacastrum, _Gray_, Manual, not _L._)--Sea coast, N. J. to Fla.
2. MOLLÙGO, L. INDIAN-CHICKWEED.
Sepals 5, white inside. Stamens hypogynous, 5 and alternate with the
sepals, or 3 and alternate with the 3 cells of the ovary. Stigmas 3.
Capsule 3-celled, 3-valved, loculicidal, the partitions breaking away
from the many-seeded axis.--Low homely annuals, much branched, the
stipules obsolete. (An old Latin name for some soft plant.)
M. VERTICILLÀTA, L. (CARPET-WEED.) Prostrate, forming patches; leaves
spatulate, clustered in whorls at the joints, where the 1-flowered
pedicels form a sort of sessile umbel, stamens usually 3.--Sandy
river-banks, and cultivated grounds. June--Sept. (An immigrant from
farther south.)
ORDER 48. UMBELLÍFERÆ. (PARSLEY FAMILY.)
_Herbs, with small flowers in umbels (or rarely in heads), the calyx
entirely adhering to the 2-celled and 2-ovuled ovary, the 5 petals and 5
stamens inserted on the disk that crowns the ovary and surrounds the
base of the 2 styles. Fruit consisting of 2 seed-like dry carpels._ Limb
of the calyx obsolete, or a mere 5-toothed border. Petals either
imbricated in the bud or valvate with the point inflexed. The two
carpels (called _mericarps_) cohering by their inner face (the
_commissure_), when ripe separating from each other and usually
suspended from the summit of a slender prolongation of the axis
(_carpophore_); each carpel marked lengthwise with _5 primary ribs_, and
often with 4 intermediate (_secondary_) ones; in the _interstices_ or
_intervals_ between them are commonly lodged the oil-tubes (_vittæ_),
which are longitudinal canals in the substance of the fruit, containing
aromatic oil. (These are best seen in slices made across the fruit.)
Seed suspended from the summit of the cell, anatropous, with a minute
embryo in hard albumen.--Stems usually hollow. Leaves alternate, mostly
compound, the petioles expanded or sheathing at base, rarely with true
stipules. Umbels usually compound, in which case the secondary ones are
termed _umbellets_; the whorl of bracts which often subtends the general
umbel is the _involucre_, and those of the umbellets the _involucels_.
The base of the styles is frequently thickened and cushion-like, and
called the _stylopodium_. In many the flowers are _dichogamous_, i.e.
the styles are protruded from the bud some time before the anthers
develop,--an arrangement for cross-fertilization.--A large family, some
of the plants innocent and aromatic, others with very poisonous
(acrid-narcotic) properties. The flowers are much alike in all, and the
fruits, inflorescence, etc., likewise exhibit comparatively small
diversity. The family is consequently difficult for the young student.

DIVISION II. GAMOPETALOUS DICOTYLEDONOUS PLANTS.
Floral envelopes consisting of both calyx and corolla, the latter
composed of more or less united petals, that is, gamopetalous.[A]
[Footnote A: In certain families, as in Ericaceæ, etc., the petals in
some genera are nearly or quite separate. In Compositæ and some others,
the calyx is mostly reduced to a pappus, or a mere border, or even to
nothing more than a covering of the surface of the ovary. The student
might look for these in the first or the third division; but the
_artificial analysis_ prefixed to the volume provides for such
anomalies, and will lead him to the proper order.]

ORDER 55. COMPÓSITÆ. (COMPOSITE FAMILY.)
_Flowers in a close head_ (the compound flower of the older botanists),
_on a common receptacle, surrounded by an involucre, with 5 (rarely 4)
stamens inserted on the corolla, their anthers united in a tube
(syngenesious)._--Calyx-tube united with the 1-celled ovary, the limb
(called a _pappus_) crowning its summit in the form of bristles, awns,
scales, teeth, etc., or cup-shaped, or else entirely absent. Corolla
either strap-shaped or tubular; in the latter chiefly 5-lobed, valvate
in the bud, the veins bordering the margins of the lobes. Style 2-cleft
at the apex (in sterile flowers usually entire). Fruit seed-like
(_achene_), dry, containing a single erect anatropous seed, with no
albumen.--An immense family, in temperate regions chiefly herbs, without
stipules, with perfect, polygamous, monœcious or diœcious flowers. The
flowers with a strap-shaped (_ligulate_) corolla are called _rays_ or
_ray-flowers_; the head which presents such flowers, either throughout
or at the margin, is _radiate_. The tubular flowers compose the _disk_;
and a head which has no ray-flowers is said to be _discoid_. When the
head contains two sorts of flowers it is said to be _heterogamous_; when
only one sort, _homogamous_. The leaves of the involucre, of whatever
form or texture, are termed _scales_. The bracts or scales, which often
grow on the receptacle among the flowers, are called the _chaff_; when
these are wanting, the receptacle is said to be _naked_.--The largest
order of Phænogamous plants. The genera are divided by the corolla into
three series, only two of which are represented in the Northern United
States. The first is much the larger.

_cup top-shaped_, coarse-scaly; acorn short-ovoid.--Dry sandy barrens,
or heavy clay soil, Long Island to S. Minn., E. Neb., and southward. A

S. FRAGILIS is also scarce, but a host of hybrids between the two,
representing S. viridis, _Fries_, S. Russelliana, _Smith_, etc., are the

flowered and more silvery silky; leaves sometimes retaining a
ferruginous pubescence beneath even when fully grown.--Var. PRINOÌDES,
Anders. Aments more loosely flowered, less silky; capsules more thinly
tomentose; style longer; stigma-lobes laciniate; leaves narrower. (S.
prinoides, _Pursh._) Includes narrow-leaved forms of the type, and
others which are probably hybrids with S. cordata.--Low meadows and
river-banks, common. The just expanding leaves are often overspread with
evanescent ferruginous hairs.

attenuate-rostrate capsules.--Common, but more prevalent from the Great
Lakes westward. This species, like the preceding, hybridizes freely with
S. cordata.

coriaceous, few-seeded.--Perennial slender submerged herbs, with
elongated branching stems, thickly beset with pellucid and veinless,
1-nerved, sessile, whorled or opposite leaves. The staminate flowers
(rarely seen) commonly break off, as in Vallisneria, and float on the
surface, where they expand and shed their pollen around the stigmas of
the fertile flowers, raised to the surface by the prolonged calyx-tube,
which varies in length according to the depth of the water. (Name from
ἑλώδης, _marshy_.)

Stigmas 3, large, nearly sessile, 2-lobed. Ovules very numerous,
scattered over the walls, orthotropous. Fruit elongated, cylindrical,
berry-like.--Stemless plants, with long linear grass-like leaves, wholly
submerged. The staminate clusters being confined to the bottom by the
shortness of the scape, the flower-buds themselves break from their
short pedicels and float on the surface, where they shed their pollen
around the fertile flowers, which are raised to the surface by sudden
growth at the same time; afterwards the thread-form scapes (2--4 feet
long) coil up spirally, drawing the fruit under water to ripen. (Named
for _Ant. Vallisneri_, an early Italian botanist.)

innumerable minute seeds, appearing like fine saw-dust. Perianth of 6
divisions in 2 sets; the 3 outer (_sepals_) mostly of the same
petal-like texture and appearance as the 3 inner (_petals_). One of the
inner set differs more or less in figure, direction, etc., from the
rest, and is called the _lip_; only the other two taking the name of
_petals_ in the following descriptions. The lip is really the upper
petal, i.e. the one next to the axis, but by a twist of the ovary of
half a turn it is more commonly directed forward and brought next the
bract. Before the lip, in the axis of the flower, is the _column_,
composed of a single stamen, or in Cypripedium of two stamens and a
rudiment of a third, variously coherent with or borne on the style or
thick fleshy stigma; anther 2-celled; each cell containing one or more

16. CÀREX, Ruppius. SEDGE. (By L. H. BAILEY.)
Flowers unisexual, destitute of floral envelopes, disposed in spikes;
the staminate consisting of three stamens, in the axil of a bract, or
_scale_; the pistillate comprising a single pistil with a bifid or
trifid style, forming in fruit a hard lenticular or triangular achene,
which is enclosed in a sac (_perigynium_) formed by the complete union
of the borders of a bractlet or of connate bractlets and borne in the
axil of a bract, or _scale_. Staminate and pistillate flowers borne in
different parts of the spike (spike _androgynous_), or in separate
spikes on the same culm, or rarely the plant diœcious.--Perennial
grass-like herbs with mostly triangular culms, 3-ranked leaves, usually
with rough margins and keel, and spikes in the axils of leafy or
scale-like bracts, often aggregated into heads. An exceedingly critical
genus, the study of which should be attempted only with complete and
fully mature specimens. (The classical Latin name, of obscure
signification; derived by some from κείρω, _to cut_, on account of the
sharp leaves--as the English name _Shear-grass_.) (Pl. 5 and 6.)

ORDER 129. GRAMÍNEÆ. (GRASS FAMILY.)
_Grasses, with usually hollow stems_ (culms) _closed at the joints,
alternate 2-ranked leaves, their sheaths split or open on the side
opposite the blade; the hypogynous flowers solitary in the axils of
imbricated 2-ranked glumes_, forming a 1--many-flowered _spikelet_; the
lower glumes (1 or usually 2) empty, the succeeding _flowering glumes_
enclosing each a somewhat smaller and usually thinner scale (called the
_palet_) and 2 or 3 very minute hyaline scales (_lodicules_) at the base
of the flower. Stamens 1--6, commonly 3; anthers versatile, 2-celled,
the cells distinct. Styles mostly 2 or 2-parted; stigmas hairy or

from, sometimes permanently adherent to, the palet.--A vast and most
important family, as it furnishes the cereal grains, and the principal
food of cattle, etc. The terms _flowering glume_ and _palet_ are now
adopted in place of the _outer_ and _inner palets_ of previous editions,

SERIES II.
CRYPTOGAMOUS OR FLOWERLESS PLANTS.
Vegetables destitute of proper flowers (i.e. having no stamens nor
pistils), and producing instead of seeds minute one-celled germinating
bodies called _spores_, in which there is no embryo or rudimentary
plantlet.
CLASS III. ACROGENS.
Cryptogamous plants with a distinct axis or stem, growing from the apex,
and commonly not with later increase in diameter, usually furnished with
distinct leaves; reproduction by antheridia and archegonia, sometimes
also by gemmation.
SUBCLASS I. VASCULAR ACROGENS, OR PTERIDOPHYTES.[1]
[Footnote 1: The orders of this Subclass have been elaborated anew for
this edition by Prof. DANIEL C. EATON of Yale University.]
Stems containing woody fibre and vessels (especially scalariform or
spiral ducts). Antheridia or archegonia, or both, formed on a minute
prothallus which is developed from the spore on germination, the
archegonium containing a nucleus, which after fertilization becomes an
oöspore and at length grows into the conspicuous spore-bearing plant.
ORDER 130. EQUISETÀCEÆ. (HORSETAIL FAMILY.)
_Rush-like, often branching plants, with jointed and mostly hollow stems
from running rootstocks, having sheaths at the joints, and, when
fertile, terminated by the conical or spike-like fructification composed
of shield-shaped stalked scales bearing the spore-cases beneath._--A
single genus.
1. EQUISÈTUM, L. HORSETAIL. SCOURING RUSH. (Pl. 21)
Spore-cases (_sporangia, thecæ_) 6 or 7, adhering to the under side of
the angled shield-shaped scales of the spike, 1-celled, opening down the
inner side and discharging the numerous loose spores. To the base of
each spore are attached 4 thread-like and club-shaped elastic filaments,
which roll up closely around the spore when moist, and uncoil when
dry.--Rootstocks perennial, wide-creeping, hard and blackish, jointed,
often branched and sometimes bearing small tubers. Stems erect,
cylindrical, hollow, jointed; the surface striated or grooved with
alternate ridges and furrows, the cuticle in most species containing
silica in the form of minute granules, rosettes, or tubercles; the
joints containing besides the central air-cavity a circle of smaller
hollows beneath the furrows and a set of still smaller ones beneath the
ridges; the nodes closed and solid, each bearing instead of leaves a
sheath which is divided into teeth corresponding in number and position
to the principal ridges of the stem; stomata in the furrows, each with
two pairs of guard-cells, of which the outer pair is marked with
radiating lines of silica. Branches, when present, in whorls from the
base of the sheath, like the stem, but without the central air-cavity.
Prothallus green, formed upon the ground, often variously lobed, usually
diœcious. (The ancient name, from _equus_, horse, and _seta_, bristle.)

ORDER 131. FÍLICES. (FERNS.)
_Leafy plants, with the leaves_ (fronds) _usually raised on a stalk or
petiole_ (stipe), _rising from a_ (sometimes greatly elongated)
_rootstock, separately rolled up_ (circinate) _in the bud, and bearing
on the under surface or along the margin small reticulated sporangia,
which at length split open and discharge the numerous minute spores.

SUBORDER I. Polypodiàceæ. Sporangia collected in dots, lines, or
variously shaped clusters (_sori_ or _fruit-dots_) on the back or
margins of the frond or its divisions, cellular-reticulated, stalked,
the stalk running into a vertical incomplete many-jointed ring, which by
straightening at maturity ruptures the sporangium transversely on the
inner side, discharging the spores. Fruit dots often covered (at least

_involucre_), growing either from the back or the margin of the frond.
(Plates 16--19.)
Tribe I. POLYPODIEÆ. Fructification on the back of the frond, in round
or roundish fruit-dots (_sori_) placed on the veins or at the ends of

tips of the veins; under surface of the frond usually either chaffy,
woolly, or powdery.
Tribe III. PTERIDEÆ. Fructification marginal or intramarginal, provided
with a general indusium formed of the (either altered or unchanged)
margin of the frond. Stipes not articulated to the rootstock. Veins free
in all our species.

ORDER 133. LYCOPODIÀCEÆ. (CLUB-MOSS FAMILY.)
Low plants, usually of moss-like aspect, with elongated and often much
branched stems covered with small lanceolate or subulate, rarely oblong
or rounded, persistent entire leaves; the sporangia 1--3-celled,
solitary in the axils of the leaves, or on their upper surface, when
ripe opening into two or three valves, and shedding the numerous yellow
spores, which are all of one kind.--The Order, as here defined, consists
mainly of the large genus
1. LYCOPÒDIUM, L. CLUB-MOSS. (Pl. 21.)
Spore-cases coriaceous, flattened, usually kidney-shaped, 1-celled,
2-valved, mostly by a transverse line round the margin, discharging the
subtile spores in the form of a copious sulphur-colored inflammable
powder.--Perennials, with evergreen one-nerved leaves, imbricated or
crowded in 4--16 ranks. (Name compounded of λύκος, _a wolf_, and ποῦς,
_foot_, from no obvious resemblance.)
§ 1. _Spore-cases in the axils of the ordinary (dark green and shining,
rigid, lanceolate, about 8-ranked) leaves._
1. L. Selàgo, L. Stems erect and rigid, dichotomous, forming a
level-topped cluster (3--6´ high); _leaves uniform_, crowded, ascending,
glossy, pointed, entire or denticulate; sporangia in the axils of
unaltered leaves.--Mountain-tops, Maine to Lake Superior, and
northward.--The leaves of this and the next species often bear little
gemmæ, with the lower bracts pointed, and the 2--3 uppermost broadly
obovate and fleshy, as figured in 1768 by Dillenius. These gemmæ fall to
the ground and their axis grows into the stem of a new plant, as
specimens collected in 1854 show very plainly. (For their true nature
see Sachs' Lehrbuch, Engl. trans., p. 411.)
2. L. lucídulum, Michx. Stems assurgent, less rigid, dichotomous (6--12´
long); leaves pointed, toothed, at first spreading, then deflexed,
arranged, in alternate zones of shorter and longer leaves, the shorter
leaves more frequently bearing sporangia in their axils; proliferous
gemmæ usually abundant.--Cold, damp woods; common northward. Aug.
§ 2. _Spore-cases only in the axils of the upper (bracteal) leaves, thus
forming a spike._
[*] _Leaves of the creeping sterile and of the upright fertile stems or
branches and those of the simple spike nearly alike, many-ranked._
3. L. inundàtum, L. _Dwarf_; creeping sterile stems forking, flaccid;
the fertile solitary (1--4´ high), bearing a short thick spike; _leaves
lanceolate or lance-awl-shaped, acute_, soft, spreading, _mostly
entire_, those of the prostrate stems curving upward.--Var. BIGELÒVII,
Tuckerm., has fertile stems 5--7´ high, its leaves more awl-shaped and
pointed, sparser and more upright, often somewhat teeth-bearing.--Sandy
bogs, northward, not common; the var., eastern New Eng. to N. J., and
southward. Aug. (Eu.)
4. L. alopecuroìdes, L. _Stems stout_, very densely leafy throughout;
the sterile branches recurved-procumbent and creeping; the fertile of
the same thickness, 6--20´ high; _leaves narrowly linear-awl-shaped,
spinulose-pointed, spreading, conspicuously bristle-toothed below the
middle; those of the cylindrical spike with long setaceous
tips_.--Pine-barren swamps, N. J. to Va., and southward. Aug.,
Sept.--Stems, including the dense leaves, ½´ thick; the comose spike,
with its longer spreading leaves, ¾--1´ thick.
[*][*] _Leaves (bracts) of the catkin-like spike scale-like, imbricated,
yellowish, ovate or heart-shaped, very different from those of the
sterile stems and branches._
[+] _Spikes sessile (i.e. branches equally leafy to the top), single._
5. L. annótinum, L. Much branched; _stems prostrate and creeping_ (1--4°
long); _the ascending branches similar_ (5--8´ high), sparingly forked,
the sterile ones making yearly growths from the summit; _leaves equal,
spreading_, in about 5 ranks, rigid, lanceolate, pointed, minutely
serrulate (pale green); spike solitary, oblong-cylindrical, thick.--Var.
PÚNGENS, Spring, is a reduced sub-alpine or mountain form, with shorter
and more rigid pointed erectish leaves.--Woods; common northward; the
var. on the White Mountains, with intermediate forms around the base.
July. (Eu.)
6. L. obscùrum, L. Rootstock cord-like, subterranean, bearing scattered,
erect, tree-like stems dividing at the summit into several densely
dichotomous spreading branches; leaves linear-lanceolate, decurrent,
entire, acute, 6-ranked, those of the two upper and two lower ranks
smaller and appressed, the lateral ones incurved spreading; spikes
1--10, erect, mostly sessile; bracts scarious-margined, broadly ovate,
abruptly apiculate.--Var. DENDROÍDEUM (L. deudroideum, _Michx._) has all
the leaves alike and incurved spreading.--Moist woods. Aug.--Remarkable
for its tree-like appearance.
L. ALPÌNUM, L., or its var. SABINÆFÒLIUM, occurs from Labrador to
Washington Territory, and is to be expected in northern Maine and Minn.
It has slender branches with rigid nearly appressed leaves.
[+][+] _Spikes peduncled, i.e. the leaves minute on the fertile
branches._
[++] _Leaves homogeneous and equal, many-ranked; stems terete._
7. L. clavàtum, L. (COMMON CLUB-MOSS.) Stems creeping extensively, with
similar ascending short and very leafy branches; the fertile terminated
by a slender peduncle (4--6´ long), bearing about 2--3 (rarely 1 or 4)
linear-cylindrical spikes; leaves linear-awl-shaped, incurved spreading
(light green), tipped, as also the bracts, with a fine bristle.--Dry
woods; common, especially northward. July. (Eu.)
[++][++] _Leaves of two forms, few-ranked; stems or branches flattened._
8. L. Caroliniànum, L. (Pl. 21.) Sterile stems and their few short
branches _entirely creeping_ (leafless and rooting on the under side),
thickly clothed with broadly lanceolate acute and somewhat oblique
1-nerved _lateral leaves widely spreading in 2 ranks_, and a shorter
intermediate row appressed on the upper side; also sending up a slender
simple peduncle (2--4´ high, clothed merely with small bract-like and
appressed awl-shaped leaves), _bearing a single cylindrical spike_.--Wet
pine-barrens, N. J. to Va., and southward.
9. L. complanàtum, L. (GROUND-PINE.) Stems extensively creeping (often
subterranean), the erect or _ascending branches several times forked
above_; bushy _branchlets crowded, flattened_, fan-like and spreading,
_all clothed with minute imbricated-appressed awl-shaped leaves in 4
ranks_, with decurrent-united bases, the lateral rows with somewhat
spreading tooth-like tips, those of the upper and under rows smaller,
narrower, wholly appressed; peduncle slender, _bearing 2--4 cylindrical
spikes_.--Var. CHAMÆCYPARÍSSUS has narrower, more erect and bushy
branches, and the leaves less distinctly dimorphous.--Woods and
thickets; common, especially northward. (Eu.)
ORDER 134. SELAGINELLÀCEÆ.
Leafy plants, terrestrial or rooted in mud, never very large; the stems
branching or short and corm-like; the leaves small and 4--6-rowed, or
subulate and elongated; sporangia one-celled, solitary, axillary or
borne on the upper surface of the leaf at its base and enwrapped in its
margins, some containing large spores (_macrospores_) and others small
spores (_microspores_). The macrospores are in the shape of a low
triangular pyramid with a hemispherical base, and marked with elevated
ribs along the angles. In germination they develop a minute prothallus
which bears archegonia to be fertilized by antherozoids developed from
the microspores.
1. Selaginella. Terrestrial; stems slender; leaves small; sporangia
minute and axillary.
2. Isoetes. Aquatic or growing in mud; stems corm-like: leaves elongated
and rush-like; sporangia very large, enwrapped by the dilated bases of
the leaves.
1. SELAGINÉLLA, Beauv. (Pl. 21.)
Fructification of two kinds, namely, of minute and oblong or globular
spore-cases, containing reddish or orange-colored powdery microspores;
and of mostly 2-valved tumid larger ones, filled by 3 or 4 (rarely 1--6)
much larger globose-angular macrospores; the former usually in the upper
and the latter in the lower axils of the leafy 4-ranked sessile spike,
but sometimes the two kinds are on opposite sides all along the spike.
(Name a diminutive of _Selago_ an ancient name of a Lycopodium, from
which this genus is separated, and which the plants greatly resemble in
habit and foliage.)
[*] _Leaves all alike and uniformly imbricated; those of the spike
similar._
1. S. spinòsa, Beauv. _Sterile stems prostrate_ or creeping, small and
slender; _the fertile thicker, ascending, simple_ (1--3´ high); _leaves
lanceolate, acute, spreading, sparsely spinulose-ciliate_. (S.
selaginoides, _Link._)--Wet places, N. H. (_Pursh_), Mich., Lake
Superior, Colorado, and northward; rare.--Leaves larger on the fertile
stems, yellowish-green. (Eu.)
2. S. rupéstris, Spring. (Pl. 21, fig. 1--4.) _Much branched in close
tufts_ (1--3´ high); _leaves densely appressed-imbricated,
linear-lanceolate_, convex and with a grooved keel, _minutely ciliate,
bristle-tipped_; those of the strongly quadrangular spike rather
broader.--Dry and exposed rocks; very common.--Grayish-green in aspect,
resembling a rigid Moss. Very variable farther west and south. (Eu.)
[*][*] _Leaves shorter above and below, stipule-like; the lateral
larger, 2-ranked._
3. S. àpus, Spring. Stems tufted and prostrate, creeping, much branched,
flaccid; leaves pellucid-membranaceous, the larger spreading
horizontally, ovate, oblique, mostly obtuse, the smaller appressed,
taper-pointed; those of the short spikes nearly similar; larger spore
cases copious at the lower part of the spike.--Low, shady places; not
rare, especially southward.--A delicate little plant, resembling a Moss
or Jungermannia.
2. ISÒETES, L. QUILLWORT. (Pl. 21.)
Stem or trunk a fleshy more or less depressed corm, rooting just above
its 2-lobed (or in many foreign species 3-lobed) base, above covered
with the dilated and imbricated bases of the awl-shaped or linear
somewhat quadrangular leaves, which include four air-tubes, intercepted
by cross partitions. Sporangia pretty large, orbicular or ovoid,
plano-convex, very thin, sessile in the axils of the leaves, and united
at the back with their excavated bases (the thin edges of the excavation
folding round partly cover them, forming the _velum_), traversed
internally by transverse threads; those of the outer leaves filled with
large spherical macrospores, their whitish crustaceous integument marked
by one circular, and on the upper surface by three radiating elevated
lines (circumscribing a lower hemisphere, and three upper segments which
open valve-like in germination); those of the inner leaves filled with
very minute and powdery grayish microspores; these are always obliquely
oblong and triangular.--Mostly small aquatics, grass-like or rush-like
in aspect, some always submerged, others amphibious, a few living in
merely moist soil, maturing their fruit in late summer and early autumn,
except n. 7 and some forms of n. 6.
This genus is left essentially as it was elaborated for the 5th edition
by the late Dr. GEORGE ENGELMANN. The present editor has added to the
range of a few species, and given var. robusta of n. 3.

ORDER 135. MARSILIÀCEÆ.
Perennial plants rooted in mud, having a slender creeping rhizome and
either filiform or 4-parted long-petioled leaves; the somewhat
crustaceous several-celled sporocarps borne on peduncles which rise from
the rhizome near the leaf-stalks, or are more or less consolidated with
the latter, and contain both macrospores and microspores.
1. MARSÌLIA, L. (Pl. 25.)
Submersed or emersed aquatic plants, with slender creeping rootstocks,
sending up elongated petioles, which bear at the apex a whorl of four
nervose-veined leaflets, and at or near their base, or sometimes on the
rootstock, one or more ovoid sporocarps. These sporocarps or fruit
usually have two teeth near the base, and are 2-celled vertically, with
many transverse partitions, and split or burst into 2 valves at
maturity. The sporocarps have a ring along the edges of the valves,
which at length swells up and bears the sausage-shaped compartments from
their places. The compartments contain macrosporangia and microsporangia
intermixed. (Named for _Aloysius Marsili_, an early Italian naturalist.)
1. M. quadrifòlia, L. Leaflets broadly obovate-cuneate, glabrous;
sporocarps usually 2 or 3 on a short peduncle from near the base of the
petioles, pedicelled, glabrous or somewhat hairy, the basal teeth small,
obtuse, or the upper one acute.--In water, the leaflets commonly
floating on the surface; Bantam Lake, Litchfield, Conn., and now
introduced in many places. (Eu.)
2. M. vestìta, Hook. & Grev. Leaflets broadly cuneate, usually hairy,
entire (2--7´´ long and broad); petioles 1--4´ long; peduncles free from
the petiole; sporocarps solitary, short-peduncled (about 2´´ long), very
hairy when young; upper basal tooth of sporocarp longest, acute,
straight or curved, lower tooth acute, the sinus between them rounded.
(M. mucronata, _Braun_.)--In swamps which become dry in summer; Iowa and
southwestward.
ORDER 136. SALVINIÀCEÆ.
Floating plants of small size, having a more or less elongated and
sometimes branching axis, bearing apparently distichous leaves;
sporocarps or conceptacles very soft and thin-walled, two or more on a
common stalk, one-celled and having a central, often branched receptacle
which bears either macrosporangia containing solitary macrospores, or
microsporangia with numerous microspores.
1. AZÓLLA, Lam. (Pl. 21.)
Small moss-like plants, the stems pinnately branched, covered with
minute 2-lobed imbricated leaves, and emitting rootlets on the under
side. Conceptacles in pairs beneath the stem; the smaller ones
acorn-shaped, containing at the base a single macrospore with a few
corpuscles of unknown character above it; the larger ones globose, and
having a basal placenta which bears many pedicellate microsporangia
which contain masses of microspores.
1. A. Caroliniàna, Willd. Plants somewhat deltoid in outline (4--12´´
broad), much branched; leaves with ovate lobes, the lower lobe reddish,
the upper one green with a reddish border; macrospores with three
attendant corpuscles, its surface minutely granulate; masses of
microspores glochidiate.--Floating on quiet waters, from Lake Ontario
westward and southward,--appearing like a reddish hepatic moss.
* * * * *
SALVÍNIA NÀTANS, L., was said by Pursh to grow floating on the surface
of small lakes in Western New York, and has more recently been said to
occur in Missouri. It has oblong-oval floating leaves 4--6´´ long,
closely pinnately-veined, which bear conceptacles and branching plumose
fibres on their under surface.
SUBCLASS II. CELLULAR ACROGENS, OR BRYOPHYTES.
Plants composed of cellular tissue only. Antheridia or archegonia, or
both, formed upon the stem or branches of the plant itself, which is
developed from the germinating spore usually with the intervention of a
filiform or conferva-like prothallus.--Divided into the _Musci_, or
Mosses, and the _Hepaticæ_.
DIVISION I. HEPÁTICÆ.[1] (LIVERWORTS.)
[Footnote 1: Elaborated for this edition by Prof. L. M. UNDERWOOD, of
Syracuse, N. Y.]
Plants usually procumbent, consisting of a simple thallus, a thalloid
stem, or a leafy axis; leaves when present 2-ranked, with uniform
leaf-cells and no midvein; thalloid forms with or without a midvein,
smooth or scurfy or scaly beneath and usually with numerous rootlets.
Sexual reproduction by antheridia and archegonia, which are immersed in
the thallus, or sessile or pedicelled upon it, or borne on a peduncled
receptacle. The fertilized archegonium develops into a capsule
(_sporogonium_) closely invested by a calyptra, which ruptures above as
the ripened capsule (containing numerous spores and usually elaters)
pushes upward. It is also commonly surrounded by a usually double
involucre, the inner (often called _perianth_) more or less tubular, the
outer tubular or more often foliaceous, sometimes wholly wanting.
Propagation is also effected by offshoots (_innovations_), runners
(_flagella_), or by _gemmæ_, which appear at the margin of the leaves or
on the surface of the thallus, often in special receptacles.
ORDER 137. JUNGERMANNIÀCEÆ. SCALE-MOSSES.
Plant-body a leafy axis or rarely thallose. Capsule borne on a slender
often elongated pedicel, splitting at maturity into 4 valves. Elaters
mixed with the spores, mostly bispiral (unispiral in n. 1--3, 32, and
33, 1--3-spiral in n. 5 and 28). Antheridia and archegonia diœcious or
monœcious, in the latter case either mingled in the same inflorescence,
or separated upon the same branch, with the antheridia naked in the
axils of the lower leaves, or on separate parts of the same plant.
Leaves 2-ranked, incubous (i.e. the apex of each leaf lying on the base
of the next above), or succubous (i.e. the apex of each leaf lying under
the base of the next above), or sometimes transverse, with frequently a
third row of rudimentary leaves beneath the stem.
