SWAMP PLANTS.
Skunk-Cabbage.
Synonyms--Dracontium Foetidum L.
Other Common Names--Dracontium, skunk-weed, polecat-weed,
swamp-cabbage, meadow-cabbage, collard, fetid, hellebone, stinking
poke, pockweed.
Habitat and Range--Swamps and other wet places from Canada to
Florida, Iowa and Minnesota abound with this ill-smelling herb.
Description of Plant--Most of the common names applied to this plant,
as well as the scientific names, are indicative of the most striking
characteristic of this early spring visitor, namely, the rank,
offensive, carrion odor that emanates from it. Skunk-Cabbage is one
of the very earliest of our spring flowers, appearing in February or
March, but it is safe to say that it is not likely to suffer
extermination at the hand of the enthusiastic gatherer of spring
flowers. In the latitude of Washington Skunk-Cabbage has been known
to be in flower in December.
It is a curious plant, with its hood shaped, purplish striped flowers
appearing before the leaves. It belongs to the arum family (Araceae)
and is a perennial. The "flower" is in the form of a thick, ovate,
swollen spathe, about 3 to 6 inches in height, the top pointed and
curved inward, spotted and striped with purple and yellowish green.
The spathe is not like that of the wild turnip or calla lily, to
which family this plant also belongs, but the edges are rolled
inward, completely hiding the spadix. In this plant the spadix is not
spike-like, as in the wild turnip, but is generally somewhat
globular, entirely covered with numerous, dull-purple flowers. After
the fruit has ripened the spadix will be found to have grown
considerably, the spathe meantime having decayed.
The leaves, which appear after the flower, are numerous and very
large, about 1 to 3 feet in length and about 1 foot in width; they
are thin in texture, but prominently nerved with fleshy nerves, and
are borne on deeply channeled stems.
[Illustration: Skunk Cabbage (Spathyema Foetida).]
Description of Rootstock--Skunk-Cabbage has a thick, straight,
reddish brown rootstock, from 3 to 5 inches long, and about 2 inches
in diameter, and having a whorl of crowded fleshy roots which
penetrate the soil to considerable depth. The dried article of
commerce consists of either the entire rootstock and roots, which are
dark brown and wrinkled within, or of very much compressed, wrinkled,
transverse slices.
When bruised, the root has the characteristic fetid odor of the plant
and possesses a sharp acrid taste, both of which become less the
longer the root is kept.
Collection, Prices and Uses--The rootstock of Skunk-Cabbage are
collected early in spring, soon after the appearance of the flower,
or after the seeds have ripened, in August or September. It should be
carefully dried, either in its entire state or deprived of the roots
and cut into transverse slices. Skunk-Cabbage loses its odor and
acridity with age, and should therefore not be kept longer than one
season. The range of prices is from 4 to 7 cents a pound.
Skunk-Cabbage, official from 1820 to 1880, is used in affections of
the respiratory organs, in nervous disorders, rheumatism, and
dropsical complaints.
American Hellebore.
Veratrum Viride Ait.
Pharmacopoeial Name--Veratrum.
Other Common Names--True veratrum, green veratrum, American veratrum,
green hellebore, swamp-hellebore, big hellebore, false hellebore,
bear-corn, bugbane, bugwort, devil's-bite, earth-gall, Indian poke,
itchweed, tickleweed, duckretter.
Habitat and Range--American Hellebore is native in rich, wet woods,
swamps and wet meadows. Its range extending from Canada, Alaska, and
Minnesota south to Georgia.
Description of Plant--Early in spring, usually in company with the
Skunk-Cabbage, the large bright green leaves of American Hellebore
make their way thru the soil, their straight, erect leaf spears
forming a conspicuous feature of the yet scanty spring vegetation.
Later in the season a stout and erect leafy stem is sent up,
sometimes growing as tall as 6 feet. It is solid and round, pale
green, very leafy, and closely surrounded by the sheathing bases of
the leaves, unbranched except in the flowering head. The leaves are
hairy, prominently nerved, folded or pleated like a fan. They have no
stems, but their bases encircle or sheathe the main stalk, and are
very large, especially the lower ones, which are from 6 to 12 inches
in length, from 3 to 6 inches in width, and broadly oval. As they
approach the top of the plant the leaves become narrower. The
flowers, which appear from May to July, are greenish yellow and
numerous, and are borne in rather open clusters. American Hellebore
belongs to the bunchflower family (Melanthiaceae) and is a perennial.
This species is a very near relative of the European white hellebore
(Veratrum album L.), and in fact has by some been regarded as
identical with it, or at least as a variety of it. It is taller than
V. album and has narrower leaves and greener flowers. Both species
are official in the United States Pharmacopoeia.
[Illustration: American Hellebore (Veratrum Viride).]
Description of Rootstock--The fresh rootstock of American Hellebore
is ovoid or obconical, upright, thick, and fleshy, the upper part of
it arranged in layers, the lower part of it more solid, and producing
numerous whitish roots from all sides. In the fresh state it has a
rather strong, disagreeable odor. As found in commerce, American
Hellebore rootstock is sometimes entire, but more generally sliced,
and is of a light brown or dark brown color externally and internally
yellowish white. The roots, which are from 4 to 8 inches long, have a
shriveled appearance, and are brown or yellowish. There is no odor to
the dried rootstock, but when powdered it causes violent sneezing.
The rootstock, which has a bitter and very acrid taste, is poisonous.
Collection, Prices and Uses--American Hellebore should be dug in
autumn after the leaves have died and washed and carefully dried,
either in the whole state or sliced in various ways. It deteriorates
with age, and should therefore not be kept longer than a year.
The adulterations sometimes met with are the rootstocks of related
plants, and the skunk-cabbage is also occasionally found mixed with
it, but this is probably unintentional, as the two plants usually
grow close together.
Collectors of American Hellebore root receive from about 3 to 10
cents a pound.
American Hellebore, official in the United States Pharmacopoeia, is
an acrid, narcotic poison, and has emetic, diaphoretic, and sedative
properties.
Water-Eryngo.
Eryngium Yuccifolium Michx.
Synonym--Eryngium aquaticum. L.
Other Common Names--Eryngium, eryngo, button-snakeroot,
corn-snakeroot, rattlesnake-master, rattlesnake-weed,
rattlesnake-flag.
[Illustration: Water-Eryngo (Eryngium Yuccifolium).]
Habitat and Range--Altho sometimes occurring on dry land,
Water-Eryngo usually inhabits swamps and low, wet ground, from the
pine barrens of New Jersey westward to Minnesota and south to Texas
and Florida.
Description of Plant--The leaves of this plant are grasslike in form,
rigid, 1 to 2 feet long and about one-half inch or a trifle more in
width; they are linear, with parallel veins, pointed, generally
clasping at the base, and the margins briskly soft, slender spines.
The stout, furrowed stem reaches a height of from 2 to 6 feet and is
generally unbranched except near the top. The insignificant whitish
flowers are borne in dense, ovate-globular, stout-stemmed heads,
appearing from June to September, and the seed heads that follow are
ovate and scaly. Water-Eryngo belongs to the parsley family
(Apiaceae) and is native in this country.
Description of Rootstock--The stout rootstock is very knotty, with
numerous short branches, and produces many thick, rather straight
roots, both rootstock and roots of a dark brown color, the latter
wrinkled lengthwise. The inside of the rootstock is yellowish white.
Water-Eryngo has a somewhat peculiar, slightly aromatic odor, and a
sweetish mucilaginous taste at first, followed by some bitterness and
pungency.
Collection, Prices and Uses--The root of this plant is collected in
autumn and brings from 5 to 10 cents a pound.
Water-Eryngo is an old remedy and one of its early uses, as the
several common names indicate, was for the treatment of snake bites.
It was official in the United States Pharmacopoeia from 1820 to 1860,
and is employed now as a diuretic and expectorant and for promoting
perspiration. In large doses it acts as an emetic and the root, when
chewed, excites a flow of saliva. It is said to resemble Seneca
snakeroot in action.
Yellow Jasmine or Jessamine.
Gelsemium Sempervirens (L.) Ait. f.
Pharmacopoeial Name--Gelsemium.
Other Common Names--Carolina jasmine or jessamine, Carolina wild
woodbine, evening trumpet-flower.
Habitat and Range--Yellow jasmine is a plant native to the South,
found along the banks of streams, in woods, lowlands, and thickets,
generally near the coast, from the eastern part of Virginia to
Florida and Texas, south to Mexico and Guatemala.
Description of Plant--This highly ornamental climbing or trailing
plant is abundantly met with in the woods of the Southern states, its
slender stems festooned over trees and fences and making its presence
known by the delightful perfume exhaled by its flowers, filling the
air with fragrance that is almost overpowering wherever the yellow
jasmine is very abundant.
[Illustration: Yellow Jasmine (Gelsensium Sempervirens).]
The smooth, shining stems of this beautiful vine sometimes reach a
length of 20 feet. The leaves are evergreen, lance shaped, entire, 1
1/2 to 3 inches long, rather narrow, borne on short stems, and
generally remaining on the vine during the winter. The flowers, which
appear from January to April, are bright yellow, about 1 to 1 1/2
inches long, the corolla funnel shaped. They are very fragrant but
poisonous, and it is stated the eating of honey derived from jasmine
flowers has brought about fatal results.
Yellow Jasmine is a perennial and belongs to a family that is noted
for its poisonous properties, namely, the Logania family
(Loganiaceae), which numbers among its members such powerful
poisonous agents as the strychnine-producing tree.
Description of Rootstock--The rootstock of the Yellow Jasmine is
horizontal and runs near the surface of the ground, attaining great
length, 15 feet or more; it is branched, and here and there produces
fibrous rootlets. When freshly removed from the ground it is very
yellow, with a peculiar odor and bitter taste. For the drug trade it
is generally cut into pieces varying from 1 inch to 6 inches in
length, and when dried consists of cylindrical sections about 1 inch
in thickness, the roots, of course, thinner. The bark is thin,
yellowish brown, with fine silky bast fibers and the wood is tough
and pale yellow, breaking with a splintery fracture and showing
numerous fine rays radiating from a small central pith. Yellow
Jasmine has a bitter taste and a pronounced heavy odor.
Collection, Prices and Uses--The root of Yellow Jasmine is usually
collected just after the plant has come into flower and is cut into
pieces from 1 to 6 inches long. It is often adulterated with portions
of the stems, but these can be distinguished by their thinness and
dark purplish color. The prices range from 3 to 5 cents a pound.
Yellow Jasmine, which is official in the United States Pharmacopoeia,
is used for its powerful effect on the nervous system.
Sweet-Flag.
Acorus Calamus L.
Pharmacopoeial Name--Calamus.
Other Common Names--Sweet cane, sweet grass, sweet myrtle, sweet
rush, sweet sedge, sweet segg, sweetroot, cinnamon-sedge,
myrtle-flag, myrtle-grass, myrtle-sedge, beewort.
Habitat and Range--This plant frequents wet and muddy places and
borders on streams from Nova Scotia to Minnesota, southward to
Florida and Texas, also occurring in Europe and Asia. It is usually
partly immersed in water, and is generally found in company with the
cat-tail and other water-loving species of flag.
[Illustration: Sweet Flag (Acorus Calamus).]
Description of Plant--The sword like leaves of the Sweet-Flag
resemble those of other flags so much that before the plant is in
flower it is difficult to recognize simply by the appearance of its
leaves. The leaves of the blue flag or "poison-flag," as it has been
called, are very similar to those of the Sweet-Flag, and this
resemblance often leads to cases of poisoning among children who thus
mistake one for the other. However, as the leaves of the Sweet-Flag
are fragrant, the odor will be a means of recognizing it. Of course
when the Sweet-Flag is in flower the identification of the plant is
easy.
The sheathing leaves of this native perennial, which belongs to the
arum family (Araceae), are from 2 to 6 feet in height and about 1
inch in width; they are sharp pointed and have a ridged midrib
running their entire length. The flowering head, produced from the
side of the stalk, consists of a fleshy spike sometimes 3 1/2 inches
long and about one-half inch in thickness, closely covered with very
small, greenish yellow flowers, which appear from May to July.
Description of Rootstock--The long, creeping rootstock of the
Sweet-Flag is thick and fleshy, somewhat spongy, and producing
numerous rootlets. The odor is aromatic and agreeable, and taste
pungent and bitter. The dried article, as found in the stores,
consists of entire or split pieces of various lengths from 3 to 6
inches, light brown on the outside with blackish spots, sharply
wrinkled lengthwise, the upper surface marked obliquely with dark
leaf scars, and the lower surface showing many small circular scars,
which, at first glance, give one the impression that the root is
worm-eaten, but which are the remains of rootlets that have been
removed from the rootstock. Internally the rootstock is whitish and
of a spongy texture. The aromatic odor and pungent, bitter taste are
retained in the dried article.
Collection, Prices and Uses--The United States Pharmacopoeia directs
that the unpeeled rhizome, or rootstock, be used. It is collected
either in early spring or late in autumn. It is pulled or grubbed
from the soft earth, freed from adhering dirt, and the rootlets
removed, as these are not so aromatic and more bitter. The rootstock
is then carefully dried, sometimes by means of moderate heat.
Sweet-Flag deteriorates with age and is subject to the attacks of
worms. It loses about three-fourths of its weight in drying.
Some of the Sweet-Flag found in commerce consists of handsome white
pieces. These usually come from Germany, and have been peeled before
drying, but they are not so strong and aromatic as the unpeeled
roots. Unpeeled Sweet-Flag brings from 3 to 6 cents a pound.
Sweet-Flag is employed as an aromatic stimulant and tonic in feeble
digestion. The dried root is frequently chewed for the relief of
dyspepsia.
Blue Flag.
Iris Versicolor L.
Other Common Names--Iris, flag-lily, liver-lily, snake-lily,
poison-flag, water-flag, American fleur-de-lis or flower-deluce.
Habitat and Range--Blue Flag delights in wet, swampy localities,
making its home in marshes, thickets, and wet meadows from
Newfoundland to Manitoba, south to Florida and Arkansas.
Description of Plant--The flowers of all of the species belonging to
this genus are similar, and are readily recognized by their rather
peculiar form, the three outer segments or parts reflexed or turned
back and the three inner segments standing erect.
Blue Flag is about 2 to 3 feet in height, with an erect stem
sometimes branched near the top, and sword shaped leaves which are
shorter than the stem, from one-half to 1 inch in width, showing a
slight grayish "bloom" and sheathing at the base. This plant is a
perennial belonging to the iris family (Iridaceae), and is a native
of this country. June is generally regarded as the month for the
flowering of the Blue Flag, altho it may be said to be in flower from
May to July, depending on the locality. The flowers are large and
very handsome, each stem bearing from two to six or more. They
consist of six segments or parts, the three outer ones turned back
and the three inner ones erect and much smaller. The flowers are
usually purplish blue, the "claw" or narrow base of the segments,
variegated with yellow, green, or white and marked with purple veins.
All of the species belonging to this genus are more or less
variegated in color; hence the name "iris," meaning "rainbow," and
the specific name "versicolor," meaning "various colors." The name
poison-flag has been applied to it on account of the poisonous effect
it has produced in children, who, owing to the close resemblance of
the plants before reaching the flowering stage, sometimes mistake it
for sweet flag.
The seed capsule is oblong, about 1 1/2 inches and contains numerous
seeds.
[Illustration: Blue Flag (Iris Versicolor).]
Description of Rootstock--Blue Flag has a thick, fleshy, horizontal
rootstock, branched, and producing long, fibrous roots. It resembles
sweet-flag (Calamus) and has been mistaken for it. The sections of
the rootstock of Blue Flag, however, are flattened above and rounded
below; the scars of the leaf sheaths are in the form of rings,
whereas in sweet-flag the rootstock is cylindrical and the scars left
by the leaf sheaths are obliquely transverse. Furthermore, there is a
difference in the arrangement of the roots on the rootstock, the
scars left by the roots in Blue Flag being close together generally
nearer the larger end, while in sweet-flag the disposition of the
roots along the rootstock is quite regular. Blue Flag is grayish
brown on the outside when dried, and sweet-flag is light brown or
fawn colored. Blue Flag has no well-marked odor and the taste is
acrid and nauseous, and in sweet-flag there is a pleasant odor and
bitter, pungent taste.
Collection, Prices and Uses--Blue Flag is collected in autumn and
usually brings from about 7 to 10 cents a pound. Great scarcity of
Blue Flag root was reported from the producing districts in the
autumn of 1906. It is an old remedy, the Indians esteeming it highly
for stomach troubles, and it is said that it was sometimes cultivated
by them in near-by ponds on account of its medicinal value. It has
also been used as a domestic remedy and is regarded as an alterative,
diuretic and purgative. It was official in the United States
Pharmacopoeia of 1890.
Crane's-Bill.
Geranium Maculatum L.
Pharmacopoeial Name--Geranium.
Other Common Names--Spotted crane's-bill, wild crane's-bill,
stork's-bill, spotted geranium, wild geranium, alum-root, alumbloom,
chocolate-flower, crowfoot, dovefoot, old-maid's-nightcap, shameface.
Habitat and Range--Crane's-Bill flourishes in low grounds and open
woods from Newfoundland to Manitoba, south to Georgia and Missouri.
Description of Plant--This pretty perennial plant belongs to the
geranium family (Geraniaceae) and will grow sometimes to a height of
2 feet, but more generally it is only about a foot in height. The
entire plant is more or less covered with hairs, and is erect and
usually unbranched. The leaves are nearly circular or somewhat heart
shaped in outline, 3 to 6 inches wide, deeply parted into three or
five parts, each division again cleft and toothed. The basal leaves
are borne on long stems, while those above have short stems. The
flowers, which appear from April to June, are borne in a loose
cluster; they are rose purple, pale or violet in color, about 1 inch
or 1 1/2 inches wide, the petals delicately veined and woolly at the
base and the sepals or calyx lobes with a bristle-shaped point,
soft-hairy, the margins having a fringe of more bristly hairs. The
fruit consists of a beaked capsule, springing open elastically, and
dividing into five cells, each cell containing one seed.
[Illustration: Crane's-bill (Geranium Maculatum), Flowering Plant,
Showing also Seed Pods and Rootstock.]
Description of Rootstock--When removed from the earth the rootstock
of Crane's-bill is about 2 to 4 inches long, thick, with numerous
branches bearing the young buds for next season's growth and scars
showing the remains of stems of previous years, brown outside, white
and fleshy internally, and with several stout roots. When dry, the
rootstock turns a darker brown, is finely wrinkled externally, and
has a rough spiny appearance, caused by the shrinking of the buds and
branches and the numerous stem scars with which the root is studded.
Internally it is of a somewhat purplish color. Crane's-bill root is
without odor and the taste is very astringent.
Collection, Prices and Uses--Crane's-bill root depends for its
medicinal value on its astringent properties and as its astringency
is due to the tannin content, the root should, of course, be
collected at that season of the year when it is richest in that
constituent. Experiments have proved that the yield of tannin in
Crane's-bill is greatest just before flowering, which is in April or
May, according to locality. It should, therefore, be collected just
before the flowering periods, and not, as is commonly the case, in
autumn. The price of this root ranges from 4 to 8 cents a pound.
Crane's-bill root, which is official in the United States
Pharmacopoeia, is used as a tonic and astringent.
