PREFACE.

DURIXG the very ^flattering attendance wtaich,
for the last, and the present season, has been be-
stowed on the botanical lectures in this place , and
the prevailing taste which has been manifested for
the study of plants ; it was impossible not to fc el tin-,
great inconvenience arising from the defiriei icy oi'

botanical books. The common standard works of

,

the science, those containing the genera and specie*
>f plants, are hardly so much as heard of by n arac in
our bookstores. These works, even when ob taincd,
being principally in Latin, are useless to a gre it class
of amateurs of the science, who are not coftveipsant in
the learned languages. To this it may be added,
that a great number of American plants have never
been fully described, that all that is know n con-
cerning them is contained in the few wor< Is of a
specific character, which to the student, or i nexpe-
rienced botanist, can hardly afford a necess; iry de-
gree of satisfaction and certainty.

I have been influenced by these circun intances
in e&termminq to offer to the friends of botan v in this

o */

section of the country, the present colle ction of
plants, which has been undertaken with i ,lie hope

V.1

that it may be found to answer some useful purpose
as a book of practical reference, until some more
extensive work may appear among us.

The plants described in this book have been
collected during the two last seasons in the vicinity
of Boston,, within a circuit of from five to ten miles.
These limits have only been exceeded in the case of
a few remarkable plants, as Magnolia, Podophyl-
lum, &c. whose places of growth and distance from
Boston are distinctly noticed. It is presumed
however that the vegetables of this part of the coun-
try will serve as a tolerable specimen of the botany
of the whole New England states, and particularly
of the maritime parts.

No plants have been inserted, which were not
found growing spontaneously, or in their wild state.
Of these a majority are originally native, the rest
have emigrated to us from other countries. Plants
which are found growing only in a state of cultiva-
tion, are omitted ; and among others the numerous
cultivated trees and shrubs.

In describing the plants, the genera have been
placed at the head of each class, and the species
afterward in the same order, with corresponding
numbers. On account of the smallness of their
number, it has not been thought necessary to repeat
the generic characters singly, especially as many of
them are given more at large than mere essential
characters. In the species I have carefully avoid-

all changes of names or unnecessary innovations

Vll

of any sort. The specific characters have been
taken from authors with as much fidelity as was
consistent with translation, except where these
characters were found to be obviously imperfect.
In a few instances characters of superfluous length
have been abridged, fabr.J and sometimes the
terms have been changed for more convenient ones
of the same import, (m. t.J Occasionally also the
character has been taken from a synonym, and
marked accordingly, (sub syn.J

In some instances it appears probable, and even
evident, that different plants have been intended by
different authors under the same name. In these
cases I have preferred, for the present, not to
change the name, but to give it on the authority of
that author who has described the plant intended in
this work.

The principal synonyms of recent botanists
have been given. To each specific character has
been added a more full description of the plant ta-
ken from actual specimens, together with the place
f growth, time of flowering and duration, and oc-
casional remarks on the properties and uses of par-
ticular species, collected from authors, or derived
from personal observation.

The present work does not profess to contain a
complete collection of the plants of this section of
the country. Such an undertaking, neither my
present leisure and opportunities, nor the time al--
lotted for this publication, would permit. I may

\

Vlll

perhaps entertain a hope of being able at a future
period to atone in some measure for this deficiency,
At present I shall be satisfied if the work, now of-
fered to the public, should prove an auxiliary to
the study of an interesting science, and be satisfac-
tory to those friends who have obligingly aided me
with facilities during its composition. I flatter my-
self that among its faults, the most numerous will
not be its errors ; and whatever may be its fate
with the public, I shall retain the consciousness,
that it has not been the result of superficial inquiry,
or negligent observation.

This grass is extensively cultivated, forming a chief con
stituent of what is with us called English hay. It is usually
denominated herds grass, and sometimes improperly fox tail

Mr. Timothy Hanson, one of its early propagators. It is said
to have fallen there into disrepute, although its reputation is
good in this country. Professor Martyn and Mr. Curtis speak
pf it as a harsh, coarse grass, in all respects inferior to the true
foxtail grass, (Alopccurus pratensis.)

titute of beauty, or at least of singularity. All that at this time
appears above ground is the hollow, boat shaped, inflat-
ed spathe, handsomely spotted red and yellow, with its acute
top recurved. In this is the oval spadix, covered with perfect
tetrandrous flowers. The fruit is a large globular fleshy mass,
formed of the enlarged spadix, containing many large, round

49. HAMAMELIS.
HAMAMELIS VIRGINICA. L. Witch hazel,

The variegated appearance of the American forest during
the months of autumn, has been repeatedly noticed by travel-
lers. Among the crimson and yellow hues of the falling leaves
there is no more remarkable object than the Witch hazel, in
the moment of parting with its foliage, putting forth a profusion
of gaudy, yellow blossoms, and giving to November the coun-
terfeited appearance of spring. It is a bushy tree, sending up a
number of oblique trunks, about the size of a man's arm or larger.
The leaves are oval or obovate, loosely waved or^ toothed upon
the margin. Flowers in axillary bunches. Petals three or
four times as long as the calyx, yellow or straw coloured, rib-
bon shaped, spreading and reflexed. Fruit a small nut, of two
cells, terminating in two horn-like projections. Wet woods. .
October, November.

The wood is white, its fibres fine and flexible. The twigs
were formerly used in the imposture of the diving, or mineral
rods, supposed to indicate the existence of precious ores.

evergreen trees, which we possess, that are not of the conifer-
ous tribe. Its leaves are tough, smooth, and shining, furnished
at the edge with short, rigid, acute spines. The flowers are
numerous, small, of a greenish white, growing in bunches around
the branches. Berries red, falling very late. Quincy, Co-
hasset. June.

The American variety of Convolvulus sepium is one of the
finest of the genus. It climbs about fences and bushes in low
ground, its large red and white blossoms expanding in June
and July. Stem twining, a little angular, smooth. Leaves

ly toothed with large unequal teeth, unequal at base. Flowers
axillary, on short stalks, upright, white. Fruit of the size of a
small hen's egg, covered with thorns. Among rubbish. Au-
gust, September. Annual.

A variety much more common than the last, and consider-
ably larger in size, has a uniformly hollow stem, purple, cover-
ed with light dots ; the flowers light purple or blue, striped on
the inside. It answers in every respect to the description of
Datura tatula, as laid clown m botanical books. I incline to think
the two species should be incorporated into one, if there are no
better discriminating marks than those usually laid down. The
dots in the purple cuticle of the American plant do not appear
to result from warts, or any inequalities in ils structure, but
simply from variation of colour. The sensible qualities of
the two varieties are the same.

It must be remarked however, that both the plants here de-
scribed differ from the representations in the English Bctany,
and in Woodville's Medical Botany ; 1st in the form of the an-
thers, which are very oblong, four times longer than broad ; 2d
in the stigma, the sides of which are parallel ; 3d in the dissepi-
ment of the capsule which is thin, about one quarter tlxe thick-
ness of the valves.

80. ULMUS.
ULMUS AMERIC VNA L. Common Elm.

Leaves equally serrate, unequal at the base. L.

Class V. Order IL 67

This stately tree is distinguished at sight from the cultivat-
ed English elms by its long pendulous branches. It also loses
its leaves in autumn several weeks sooner. The flowers, which
appear in April, have commonly from six to eight stamens.
They are small, of a dull purple colour, and grow in bunches
on slender footstalks. The seeds are contained in a flat, oval,
winged capsule or samara, which is ciliated at the edge. The
leaves grow alternately on opposite sides of the branches ; they
are more smooth and more uniformly serrated than those of the
English elm. The wood of the elm is tough, and principally
used to form the naves or hubbs of wheels.

oval, striate, the ribs often slightly wrinkled. Road sides, and
waste ground. June, July.

The inspissated juice of this plant is extensively used in me-
dicine. Care must be taken to distinguish it from a species of
JEthusa, nearly allied to M. cynapium, (perhaps a variety) which
grows with, and very much resembles it. The ,/E.thusa is a
smaller plant, has no general involucre, and its partial ones con-
sist of three long pendulous leafets. Their taste is different,

roundish, smooth ; the partial ones very short. Leafets oval,
terminating in a short point. Peduncle long, smooth, sup-
porting a loose panicle of small flowers, which are dioecious.
Berries white.

The effluvium of this shrub is a violent poison to certain con-
stitutions, producing in them a distressing cutaneous eruption,
when it is handled or even approached. On others, and I be-
lieve on a. majority, it exerts no influence. The leaves have
been rubbed, chewed, and swallowed without injury. Their
taste is simply herbaceous and astringent, and does not indi-
cate any extraordinary quality.

with triple thorns. Leaves inversely ovate, serrate, the teeth
and point ending in short bristles. The yellow flowers appear
in June in hanging clusters ; succeeded by oblong, acid ber-
ries of a deep red colour.

A very remarkable degree of irritability, not exceeded by
the sensitive plant, exists in the flowers of the Barberry. When
these are fully expanded, the stamens are found spread out on
the inner side of the corolla. In this situation if the inside of
the filament be touched with a pin or straw, it instantly con-
tracts and throws the anther violently against Uie stigma.
This fact which has been particularly described by Dr. Smith
in the English Barberry, is not less remarkable and distinct in
the American variety of the shrub.

It is a commonly received opinion, both here and in Eu-
rope, that the barberry is injurious to cultivated grain. Wheat,
rye, Sec. growing in its neighbourhood, are said to be blighted.
But some distinguished philosophic agriculturalists, among
whom are Duhamel and Broussonet, have assured us that the
opinion is without foundation. May not the supposed fault be-
long to the peculiar soil and situation which the barberry ire*
Guents ?

flavour of the root will readily distinguish it from the other spe-
cies of flag, a name indiscriminately applied here to plants with
sword shaped leaves, as Iris, Typha, &c. When in flower, the
long, round, solitary spadix, projecting from the side of an ap-
parent leaf, is a sufficient mark. The spadix is closely cover-

Syn. LAURUS PSEUDO-BENZOIX. Mich.

An aromatic shrub with a flavour resembling Benzoin. Ear-
ly in May before the leaves appear, it puts out tufts of small,
yellow flowers from the sides of the branches. The leaves are
oval or inversely ovate, pale underneath, and somewhat pubes-
cent. Berries red. It grows in low situations at Brighton and
elsewhere, but it is not very common in the environs of Boston.

LAURUS SASSAFRAS. L. Sassafras tree,

Leaves deciduous, entire, and lobed, flowers di-

In favourable situations the Sassafras rises into a pretty large
tree. The bark of the young twigs is smooth and green. The
leaves are partly oval, and partly in two or three large lobes, en-
tire on their margin, and downy underneath. Flowers greenish
yellow, appearing in May and June in drooping clusters at the
end of the last year's shoots. They are commonly dioecious.
Fruit oval, blue.

The whole of the Sassafras tree has a strong, spicy flavour,
which is most powerful in the bark of the root. The young
twigs, and especially the pith, abound in mucilage. When first
introduced into Europe it acquired great medicinal reputation,
and was sold at the high price of fifty livres per pound. An
express treatise entitled Sassafrasologia was written to celebrate
its virtues. Its properties however appear to be those which
are common to other warm aromatics.

ROSA CAROLINIANA. L. Swamp rose

Germs globular, hispid; peduncles somewhat
hispid; stem with stipular prickles; petioles prick-
ly. L.

This rose grows in swamps and wet grounds, sometimes
forming thickets of itself. The stems vary greatly in the num-
ber and size of their prickles, even those which spring from the
same root. They are commonly of a reddish colour, and their
prickles nearly straight. Leaves pinnate, with five or seven
pair of oval leafets, sharply serrate and paler on the under side.

not seen it growing wild in the immediate vicinity of Boston,
though it is plentiful at the distance of thirty or forty miles to
the westward. Leaves simple, large, mostly five lobed, ser-
rate ; petioles and peduncles hairy. Flowers large, purple,
forming a sort of corymb. Fruit dry. Flowers in June and
after.

152. FRAG ARIA.

FRAGARIA VIRGINIANA. Ehr. Wild strawberry.

Calyx of the fruit spreading ; hairs of the peti-
oles erect, of the peduncles appressed ; leaves
smooth above. Willd.

The common wild strawberry is a very delicious fruit, and
when cultivated is inferior to few imported species. The ber-
ries ripen early, are of a light scarlet colour, exquisitely fla-
voured, but more soft and perishable than the other kinds. The
herbage is more smooth and even than in other species, the pe-
duncles shorter, so that the fruit is commonly concealed under
the leaves. Flowers white, appearing in May.

Wild strawberries are frequently sour from the circum-
stance of their ripening in the shade among the high grass.

our climate. The leaves, which are all radical, are formed by
a large hollow tube, swelling in the middle, curved and dimin-
ishing downward, till it ends in a stem, contracted at the mouth,
furnished with a large, spreading, heart shaped appendage at
top, which is hairy within ; and a broad, wavy wing extending
the whole length on the -inside. The full grown leaves will
contain a wine glass of water, and are rarely found empty. The
scape is long, smooth, and cylindrical, supporting a large, nod-

A tree of the middle size, remarkable for the neatness of
its foliage, and the regularity of its form. The leaves are large,
roundish, heart-shaped at base, finely serrated. The footstalk
supporting a bunch of flowers, proceeds from the centre of an
oblong, pale, floral leaf or bracte, as in the others of the genus.
Flowers greenish white, succeeded by small, hard, greyish cap-
sules. The wood of this tree is white, smooth, and soft. It is
used in the manufacture of certain kinds of furniture, and of
the pannels of carriages. The bark is fibrous, strong, and flex-

170. ANEMONE.
ANEMONE HEPATICA. L. Early Anemone.

Leaves three lobed, entire. L.

It is a circumstance not a little perplexing to students, tha'
the first plant in a genus without a calyx, should have a calyx
of three leaves. Linnaeus in associating this plant with the an-
emonies, considered the calyx from its remoteness, to be an in-
volucrum and not a perianth. Leaves radical, on hairy petioles,
with three broad oval lobes. Peduncles and involucre hairy. Pe-
tals red. This elegant little plant is one of the earliest visitors
in spring, flowering in sunny spots before the snow has left the

RANUNCULUS ABORTIVUS. L. Small flowered crowfoot.

Radical leaves heart-shaped, crenate ; stem
leaves ternate, angular ; stem about three flowered.
L.

This species is easily distinguished by its small flowers, and
undivided, radical leaves. The leaves which grow from the
root are heart or kidney shaped, crenate, the longest ones some-
times lobed. Stem leaves in threes, at the base of each pedun-
cle, nearly sessile, the upper ones lanceolate. Stems erect,
smooth, few flowered. Flowers small, yellow. Woods. May,
June. Perennial.

RANUNCULUS SCELEHATUS. L. Celery leaved crowfoot.

Lower leaves palmate ; uppermost in finger like
divisions ; fruit oblong.

A smooth, branching plant, with small flowers. Stem thick,
round and hollow. Lower leaves divided deeply, but not so
far as the petiole, the segments toothed and lobed. Upper
leaves sessile, divided to the bottom. Flowers numerous, on
petioles of unequal length. Calyx pubescent, somewhat de-
flected. Petals small, concave, yellow. Seeds small, in a close,
cylindrical head.- Grows in watery places. June, July. Per-
ennial. It is vepy acrid, when fresh, and may be made to pro-
duce blisters.

RANUNCULUS FASCICULARIS. Muhl. Early crowfoot.

Leaves ternate, subpinnate ; root fascicled.

An inhabitant of dry, rocky hills, flowering in April and
May. The root consists of numerous fasciculated, fleshy divi-
sions. The leaves are pubescent, but have a smooth appearance.

Those of the root grow on long stalks, and are ternate. Leafets

three lobed, remote, the terminal one deeply cleft, appearing
like three distinct leafets, so that the leaf has a pinnate form.
Peduncles a little angular. Calyx spreading, hairy underneath.
Petals longer than the calyx, transparent at base. Nectary obo-
vate. Perennial.

RANUNCULUS BULBOSUS. L. Bulbous crowfoot. Buttercups.

Calyx reflexed ; flower stalks furrowed ; stem
upright, many flowered ; leaves compound. L.

Very frequent among the grass in pastures, road sides, Sec.
The root is solid and fleshy, acrimonious and almost caustic.
Stems erect, furnished with leaves, somewhat hairy. Leaves
hairy, in three or five principal divisions, variously toothed and
cut. Flower stalks upright and furrowed. Flowers of a bright,
glossy yellow ; calyx leaves bent downward against the flower
stalk, hairy. Fruit in globular heads. May and after. Peren-
nial.

RANUNCULUS ACRIS. L. Tall crowfoot.

Calyx spreading ; flower stalks round and
even ; leaves in three divisions with many seg-
ments, the upper ones linear.

Distinguished by its superior height, being usually about
two feet high. Root fleshy, resembling the last, but smaller in
proportion to the plant. 'Root leaves large, hairy, divided into
three or five diverging lobes, which are again repeatedly sub-
divided, ending in acute segments and teeth. Petioles hairy,
especially at their ends. Uppermost leaves in three entire,
linear segments. Stem erect, branching. Flower stalks round,
not furrowed. Calyx spreading under the petals, not reflexed.
Petals large, shining, yellow. Seeds in globular heads. This
plant spreads rapidly, and is exceedingly troublesome in mea-
dows and mowing ground. Being cut with hay, it would no
doubt be pernicious to cattle, were not its acrimony lost by
drying. It flowers all summer. Perennial.

'

The flowers of this and the two last are very similar, and
confounded under the common name of Butter cups. An at-
tention to the calyx and flower stalks readily distinguishes them.
In this the leaves are mostly ternate, lobed and toothed, often
marked with a light spot at their sinuses. The plant sends out
long, prostrate stems or runners, which sufficiently distinguish
it from the others. Flower stalks furrowed as in Ranunculus
bulbosus, calyx spreading as in Ranunculus acris. Petals
bright yellow, often emarginate. Shady places. Flowering aii
summer. Perennial .

This is undoubtedly a distinct species from Ranunculus
aquatihs, having its leaves all capillary in the stillest water.
Its flowers are yellow. Stem long, smooth, furnished at regu-
lar intervals with nearly sessile leaves, divided by regular forks
into innumerable capillary segments. The flowers only
emerge from the water, Peduncles smooth, furrowed. Calyx
leaves fleshy, concave. Petals smaller than in Ranunculus bul-
bosus. Nectaries tubular. Fruit in ovate heads, the seeds
ending in a long, sharp point. In a pond on Brighton road and

elsewhere in deep water. June.

The Beech tree is known in winter by its smooth bark, its
narrow, acute buds, and marcescent leaves. The leaves are
ovate, fringed with fine hairs at the edge, furnished with paral-
lel veins like those of the Chesnut, and with indentations of mod-
crate depth at the edge. Calyx investing the fruit somewhat
ovate, muricated, with soft, short prickles. Nut triangular.

which are separated by obtuse indentations. Aments'as long as
the leaves, yellowish. The calyx investing the fruit forms a
large, globular burr, with acute, compound, crowded spines,
Nuts two or three, their upper part villous.

The American Chesnut tree is generally considered a A^ari-
ety of the European. Its wood is coarse grained, but light and
durable. It is principally employed in fencing, for which use it
furnishes one of the best materials.

263. QUERCUS.
QU.ERCUS ALBA. L. White oak.

Leaves somewhat equally pinnatificl, their seg-
ments oblong, obtuse, mostly entire ; cup bowl-
shaped, rough with tubercles ; acorn ovate. Mich,
abr.

The white oak has long been recognized among us as one
of the most valuable productions of our forests. Its name is
derived from the whiteness of the bark, a character by which it
may be distinguished at any season of the year. The leaves are
divided at their sides into a number of oblong, rounded lobes,
which are perfectly obtuse or entire, not terminating in points
or bristles. They are acute at base, their under side pale or
glaucous, and, when young, pubescent. The acorns are pretty
large, ovate, contained in the enlarged calyx, which forms a cup
of a hemispherical form, scaly and uneven on the outside.

The wood of the white oak is superior to any species in the
northern states for strength and durability. Its timber is much
used in ship building, in frames, in mills, in waggons, ploughs,
&c. and for the staves and hoops of casks. The great con-
sumption of it for these purposes, has rendered it comparative-

QUERCUS PXINUS DISCOLOR. Mich.f.

This species grows exclusively in swamps and low grounds.
It is often brought to market as fuel, and is easily distinguished
by its bark, which separates into large, flat scales or plates. The
leaves are inversely ovate or wedge shaped, not sinuated, but
bordered with a serpentine line, producing large, obtuse teeth.
They are smooth above, but white and downy underneath. The
acorns grow in pairs or single, on long stalks. They are large,
oval, with a rather small, hemispherical cup.

The wood of the swamp oak is strong, heavy, and flexible,
easy to split, and in point of durability approaches the white
oak.

The black oak grows to a large s;/e, and is uniformly char-
acterized by the rough, and very dark coloured outer bark of its
trunk. The leaves have their sides divided into a number of
large, broad, but rather short lobes, furnished with a few mu-
cronated teeth and angles. Their base is obtuse, and their un-
der surface, while young, is slightly pubescent, or glandular.
The cup of the fruit is thick, somewhat turbinated and not deep.
Acovn short and round, with its summit depressed.

The bark of this oak furnishes the Quercitron used in dyeing.
It is also one of the best species used in the tanning of leather.
The wood is much inferior to that of the white oak, but is often
used as a cheaper substitute.

QUERCUS OOCCINEA. Wang. Scarlet oak

Leaves on long petioles, oblong, deeply sinuate,

acorn short, ovate. Mich.f.

A large species of oak. The leaves are divided into long,
acute lobes, by very deep and large sinuses ; the lobes ending
in narrow teeth, which are mucronated with long, bristle shap-
ed^ points. Both sides of the leaves are of a bright, shining
green. The acorn is short and ovate, contained in a cup with
prominent scales, and tapering at base. The wood of this spe-
cies, as well as of the next, is more open and porous, also less
durable, than that of the white oak.

QUERCUS RUBRA. L. Red oak-,

Leaves on long petioles, glabrous, obtusely sin-
uate ; cup saucer shaped, nearly smooth ; acorn
nearly ovate. Mich.f.

The red oak is one of the largest of its genus. Its leaves
are smooth and shining on both sides, divided into narrow lobes,
which end in mucronated teeth, and are separated by wide and
rounded sinuses. The acorns are very large, and contained in
a remarkably flat, superficial cup, the scales of which arc so
compact as to produce a comparatively smooth surface,

The foregoing speecies constitute a considerable portion of
the growth in the common woodlands of this vicinity. Their
bark is the chief material used in tanning, and is occasionally
applied in medicine to the purposes of an astringent and anti-
septic. Next to walnut, their wood is esteemed the best fuel,
and large quantities are consumed in town, brought from the
south shore, the Middlesex canal, and the adjacent country.

cured and striated.

The shrub oak grows on dry hills and barren plains, and is
commonly considered an indication of a sterile soil. On ac-
count of its small size, it is rarely appropriated to any important
use,

greatly superior to eithei of the preceding, and in considerable
request.

The wood of the thvfee foregoing species of walnut posses-
ses similar properties. It is hard, compact, heavy, and of very
great strength. At the same time it is liable to warp and de-
cay, especially if exposed to the weather. It is principally
used for purposes where strength is required, as in hoops,
bows, the handles of tools, &c. It furnishes one of the best
kinds of fuel known, and commands a higher price in our mark-

Syn. JUGLANS CAfHA RflCA. Cutler. JMidl.f.

This tree differs from the hickories already described, in its
wood, flowers, and fruit. The leaves consist of about fifteen
leafets, which are lanceolate, rounded at base, serrate, and some-
what pubescent. The amcnts are single, not united three to-
gether, as in the foregoing species. The fruit is large, oblong,
somewhat pointed, with a viscid, adhesive surface. The nut
is oblong, acuminated, very rough, with deep, irregular depres-
sions, the kernel containing a great quantity of oil.

The wood is lighter and weaker than that of the preceding
kinds, but is said to be durable. An extract made from the
bark is in great estimation for its medicinal qualities, being one
of the most useful laxatives. According to an experiment pub-
lished in the Massachusetts Agricultural Journal, the sap of the
butternut tree is capable of producing as much sugar as that of

the maple. Four of the trees yielded in one day nine quarts of
sap, which produced one and a quarter pounds of sugar.

The name of white birch is indiscriminately applied to this
species, and to Betula papyracea, a species common in the Dis-
trict of Maine, and which furnishes a considerable part of the
eastern wood consumed in this town. The present species is
common here in swamps, and multiplies very fast in moist
lands that are not properly cleared. Like the paper birch, its
trunk is covered with a white, smooth, outer bark, separable in-
to thin layers, and very inflammable. Its young twigs are flex-
ible, of a dark brown, spotted with white. The leaves arc
heart-shaped, tapering to a long point, glutinous, smooth on
both sides. The flowers, both barren and fertile, are in lon^-,
pendulous aments. The wood is white, -soft, and very perisha-
ble, decaying sooner than the bark.

ternate, ovate, a little hearted at base, finely and acutely serrate,
acuminate. Barren flowers in pendulous aments. Fertile ones
enlarging into a sort of oblong cone, in its structure resembling
the common hop. This fruit is composed of vesicles, or in*
flated capsules, lying over each other, and containing each a
seed at its base.

The wood is hard, close grained, and heavy. In some parts
of the country it has acquired the name of Lever wood, from
the use to which it is applied.

268. PLATANUS.

PLATANUS OCCIDENTALIS, L. Plane tree. Button wood.

Sycamore.

Leaves lob ed- angular; branches whitish. Mich.

This tree, commonly known by the name of Button wood,
attains to an extraordinary size. Trees are said to be found in
the western states, whose trunks measure from forty to fifty
feet in circumference. With us it is one of the largest native
trees. The leaves are broad and lobed, with many acute seg-
ments. When young they are downy at the veins underneath.
On breaking off the petiole, the next year's bud is found con-
cealed within its base. The flowers grow in balls or globular
aments, and are succeeded by long seeds, furnished with a fine
reddish down at base. The receptacle of the seeds, constituting
the nucleus of the ball, is hard and woody, and closely enveloped
by a regular net work, which may be easily detached. The
balls art retained all winter on the trees by their tough, fibrous
stalks. Each year the outer bark of the branches scales off to a
determinate extent, leaving a white surface beneath it, This cir-
cumstance distinguishes the tree at sight from all others around
it.

The wood is fine grained, and is susceptible of a good pol-
ish. It is however said to be liable to warp, and by no means
durable when exposed to the weather.

arc ovate or pyramidal, the scales rigid, each one armed with a
short, acute, reflexed spine.

The wood abounds in turpentine, and contains a large por-
tion of alburnum or sap. It is occasionally employed in build-
ing, but is chiefly used as a light fuel, under the form of u split
pine."

PINUS srnoBus. L. White Pine.

Leaves in fives ; cones cylindrical, longer than
the leaves, loose. Ait.

This noble and very useful tree rises with a straight trunk
to an uncommon height. Its bark is comparatively smooth,
and in young trees it is without fissures. The branches are
given off in whorls or circles. The leaves are much finer and
more delicate than in the last species. They grow in fascicles
of five together, with hardly any sheaths. The cones are very
long, cylindrical, curved, and pendulous ; composed of large,
smooth, loose scales.

The trunk possesses very little resin, and its portion of sap
wood is comparatively small. The texture of the wood is fine
and soft. No tree is more extensively employed in building,
or for the ordinary purposes of carpenters' and joiners' work.
The large trees are particularly in request for the masts of
ships, and vast quantities of the wood have been annually ex-
ported from the eastern coast in the form of timber and boards.

of the branches, which are mostly horizontal. The tree flow-
ers with small aments, the barren ones containing two anthers
under each scale, and the fertile ones two germs. These last
are succeeded by small cones, with soft scales, inflected at the
edge. Seeds small, winged. This tree attains the height of

shoots. They have a peculiar, somewhat spicy taste. In au-
tumn the fertile twigs are surrounded with bunches of small,
crowded, greyish berries, which remain after the leaves have
fallen. The surface of these berries is covered with wax,
which is obtained by boiling them in water, until the wax sep-
arates and floats upon the surface. In the interior where these

particularly entitled to the attention of agriculturalists. It is a
thriving, and early grass, being usually in flower by the mid-
dle of May. It is sweet and tender, and in drying exhales a
fragrant odour, not interior to that of the sweet scented Vernal
grass. Its native place of growth is in wet, boggy meadows,
Avhcre it might be usefully substituted for the coarse and ordin-
ary grasses usually obtained from those soils.

Class XXIII. Order L

The root of this plant, when taken internally, produces vio-
lent effects, and is dangerous in considerable quantities. It is
chiefly used in the country as an external application in cutane-
ous affections. From its great affinity in habit to the Veratrum
album, an European species, which has lately acquired consid-
erable celebrity as a remedy in gout ; the American plant is
particularly entitled to the attention of phsiycians.

281. ACER.
ACER RUBRUJI. L. Sivamp Maple. Heel Maple.

Leaves palmate-live lobed, unequally toothed,
pubescent, and at length glaucous underneath, the
sinuses acute ; fertile flowers aggregate, with rath-
er long stalks. Mich.

This maple grows plentifully in our swamps and low woods.
The flowers, which appear early in May, are small, numerous,
of a deep red, and collected in little fascicles or sessile umbels.
The fertile ones are succeeded by a red fruit, known by the
name of maple keys, consisting of a pair of small capsules, each
terminated by a long, membranous appendage, resembling the
wing of an insect. The leaves are opposite, rounded, or
hearted at base, and divided into three or five principal lobes,
separated by a large, acute notch. They are irregularly tooth-
ed, and glaucous underneath.

The wood of this species is close grained, smooth, and hard,
It is much used in the manufacture of tables, chairs, and other
kinds of furniture. A variety denominated Curled Maple, oc-
casioned by the serpentine course of the fibres in some old
trees, has a beautiful, shaded appearance in cabinet work, and
is also used for gun stocks, on account of its solidity and tough-
ness.

ACER SACCHARIUM. L. Rock Maple. Sugar Maple,

the margin, glaucous underneath; flowers pedim
ciliated, pendent. Mich. f.

The Rock Maple, though common in the interior, is rarely
met with in the vicinity of Boston. Some young trees occur in
the woods at Roxbury. The flowers of this species are yellow-
ish, small, and supported by slender, drooping footstalks. The
fruit is larger than in the Red Maple, and of a light greenish col-
our. The leaves have three or five principal lobes, separated
by a sinus or notch, which is rounded, not angular, at bottom.
They are pale, and sometimes downy on the under side.

The wood is hard, compact, and smooth. It is much used
in cabinet work, particularly a beautiful variety denominated
Bird's eye Maple, and a curled variety like that in the last spe-
cies. It makes good fuel, though inferior to walnut and oak ;
and, with the Betula papyracea, it constitutes a greater portion
of our eastern wood.

But the peculiar value of this tree consists in the sugar,
which is obtained from its sap. A tree of the ordinary size will
yield from twenty to thirty gallons of sap in a season. This
sap is collected by boring holes in the trees, and affixing to
them small troughs, which convey it into reservoirs prepared
for its reception. It is then put into large kettles and boiled
down, until it is sufficiently inspissated to chrystallize or grain.
It thus forms the raw sugar, which may be purified in the usu-
al way.

282. NYSSA.
NYSSA. VILLOSA. Mich. Tupelo tree. Swamp Hornbeam.

Leaves oval, entire, the petiole, middle nerve,
and margin villous ; fertile stalks about three flow-
ered ; nut short-obovate, obtusely striate. Mich.

This tree grows in swamps, and is frequently of a pyramid-
al form, with horizontal branches. The leaves are oval, entire,
acute, tough and firm, paler on the under side, slightly pubes-

Class XXIII. Order I.

cent on the margin and petiole, two or three inches in length.
The flowers are small, obscure, of a green colour, collected on
the end of a long peduncle. Each fertile peduncle produces
two or three small, oblong drupes, of a deep blue colour, each
containing an exceedingly hard, striated stone.

The wood of this tree is white, and moderately hard. Its
fibres are closely interwoven, so as to render it extremely tough
and difficult to split. In Massachusetts it is generally called
Hornbeam, a name properly belonging to the genus Carpinus.

283. FRAXINUS.
FUAXINUS AMERICANA. Mich.f. White Ash.

Leafets elliptic, acuminate, slightly toothed, pe=
tioled, glaucous underneath.

Syn. FRAXINUS DISCOLOR. Muhl.

This very valuable tree grows to the height of seventy or
eighty feet. Its branches are opposite, and covered with bark
of a very light colour. Leaves pinnate, consisting of about
seven oval, acuminated leafets, whitish underneath, more or less
toothed on their margin. The flowers grow in loose, com-
pound racemes, and are succeeded by winged capsules. These
are cylindrical at base, but dilated at their end into a long, flat
appendage, somewhat lanceolate in form, but blunt or emargin-
atc at the end. The wood of the common Ash is exceedingly
durable, firm, and elastic, with a tolerable degree of lightness.
It is the principal material used in the manufacture of carriage
frames, of light agricultural implements, of oars, blocks, box-
es, Sec. May.

A handsome fern, not uncommon on the sides of rock^s and
steep shady hills, forming beds by means of its creeping roots.
The stalk or stipe is perfectly smooth, grooved on the upper
side. Fronds about half a foot long, divided in a pinnate man-
ner almost to the stalk or midrib, by sinuses which are more
acute than in the European variety. Segments of the frond ob-
long, parallel, rounded at the end, very slightly serrate, furnish-

Syn. J\"EPHRODIUM AcRosficnoiDES. Mich.

Remarkable for the difference between its lower and upper
leaves. The stipe is covered with loose, membranous, chaffy
scales. The leaves or pinnae are numerous, oblong, somewhat
acute, edged with small, mucronate serratures, furnished with
an angular lobe on their upper side at base. The lower leaves

cation confluent. Sm.

Common in low, moist grounds, about the edges of meadows
and swamps. Stipe glabrous. Divisions of the frond long and
slender, the lower pairs frequently decussating, or crossing each
other ; a circumstance which Dr. Smith has noticed in his spe-
cific character. They are pinnatifid, or deeply cut into oblong,
roundish segments, which are slightly crenate at the edge, and
revolute when in fruit. The first segments of each division are
at a little distance from the stipe, and seem to form a parallel
line on each side of it, running through the whole length of the
frond, a character well represented in the figure of Plukenet.
The fruit commences in small dots, and finally overruns the
whole under surface of the frond. Perennial.

This is a large, smooth, brittle fern. Divisions of the frond
pinnate ; the segments oblong, acute, with distinct teeth, separ-
ated by deep indentations. The teeth are again denticulate,
and the lower ones somewhat obtuse. Fructification with re-
niform or lunulate involucres, at first resembling lines, as in
Asplenium, afterwards extending over the whole under surface
of the frond, giving it a brownish appearance. Moist woods.

288. ADIANTUM.
ADIANTUM PBDATUM. L. Maidenhair. Mowhuir.

Frond pedate ; divisions pinnate ; segments
rhoinboid-oblong, somewhat lunate, cut-lobed.

Few vegetables possess a greater delicacy of structure than
is exhibited by the glossy stems, and fine, regular leaves of the
Maidenhair. The stipe, which is of a shining, jet black, di-
vides by a large fork into two principal branches, each df which
gives off several successive branches from its upper side ; so
that the whole frond has the appearance of a pedate leaf with-
out its middle division. The segments or leafets are alternate,
oblong, entire on the lower edge, cut and toothed on the upper.
The fruit grows in semicircular points at the margin of the leaf,
covered by the folding back of its edge. Found in moist, rocky
woods. Perennial.

pinnatifid, upper ones entire and smaller.

Very common in woods, and about the borders of fields and
pastures. Stipe erect, smooth, dividing by large, opposite
branches, which are again subdivided. Segments or leafets
sessile, oblong, tapering to an obtuse point, the lower ones larg-
est, their edge divided into large, obtuse teeth, by a sort of ser-
pentine line ; upper ones entire, obtuse. The fructification

390. ONOCLEA.
ONOCLEA SENSIBILIS. L. Sensitive fern,

Barren fronds pinnate ; segments cut, the upper
ones united ; fertile fronds doubly pinnate, with re-
curved, globular subdivisions.

A great difference, in appearance, exists between the bar-
ren, and fertile fronds of this plant. The barren frond is com-
posed of large, broad, oblong, sinuated leaves or divisions, the
lower ones distinct, the upper ones connected by their base.
The fertile frond is much narrower, its divisions short, its seg-
ments nearly globular, enclosing the fruit, and forming a sort of
raceme. Low grounds. Perennial.

291. OSMUNDA
OSMUNDA CINNAMOMEA. L. Tall Osmunda.

Barren fronds pinnate ; divisions elongated,
pinnatifid ; segments nearly oval and entire ; fertile
fronds with opposite racemes. Jllicli.

This noble fern grows in large bunches in damp woods and
low grounds, sometimes attaining to the length of a man. The
greatest part of the plant is composed by the barren fronds,
which are pinnate, their divisions cut into oblong, tapering,
rounded, and somewhat acute segments. The fruit grows on
a small, separate frond, resembling a cluster of minute, brown-
ish seeds. Its stipe is invested with loose, reddish wool, its
divisions opposite, and completely covered with small, two-
valved, globular capsules. Perennial.

O'SMUNDA INTERRUPTA. Mich. Interrupted fern,

Class XXIV. Order I.

A pretty large, smooth I'crn, in habit resembling the last.
The divisions of the frond arc principally opposite, or nearly so,
and subdivided into segments, much like the last species. Only
a few pairs of the divisions, occupying a central part of the
frond, become fruitful. These are much shorter than the rest
when full grown, they resemble compound, pyramidal racemes,
and are covered on all sides with minute, brownish capsules.
Low grounds. Perennial. ,

erect, without branches, except at base, hollow, naked, furrow-
ed, the ridges rough with minute teeth, which arc hardly visi-
ble without a glass. The joints of the stem are surrounded
with short sheaths, coloured with black and white rings, and
toothed at the top. The fruit grows in an ovate, terminal
ament) composed of peltate, six sided scales, bearing the seeds
inside.

The whole surface of the stem is rough, like a file, and is
used in scouring and polishing metallic vessels. Its cuticle,
according to Mr. Davy, contains a considerable portion of sili-
ceous earth. Perennial.

decay. They are erect, smooth, furrowed, and without branch-
es, their joints surrounded with large, swelling sheaths, which
end in long, blackish teeth. Spike terminal, oblong-ovate, with
a membranous border below it. The barren stems are taller and
more durable ; they are erect, or ascending at base, roughish,
their joints furnished with sheaths and large whorls of simple,
ascending branches. These branches are three or four cor-
nered, with sheaths at their joints, ending in the same number
of teeth. Moist ground, South Boston Perennial.

BQUISETUM STLVATICUM. L. Wood HorsetaiL

Branches compound, curving downward, rough.
