Calyx cup-shaped, obtusely 5-toothed, surrounded by a 3-leaved involucel;
the leaflets united and cordate at the base, deeply toothed and incised. Styles
united : stigmas 3, sometimes 5. Capsule 3-5-eelled, loculicidal. Seeds numerous,
imbedded in cotton.—Young branches and leaves more or less conspicuously
covered with black dots ; the nerves beneath usually with one or
more glands.—Cotton-plant.
1. G. herbaceum (Linn.): leaves 3-5-lobed, with a single gland below;
lobes mucronate; cotton white.—DC. prodr. 1 p. 456.
Southern States & Florida! naturalized in some places.—Thirteen species
of Cotton are described by De Candolle, and many more are enumerated
by some writers. Dr. Hamilton (Linn, trans. 13. p. 492), who is followed
by Wight & Arnott, reduces twelve of De Candolle’s species to two, viz :
G. album (Ham.): seeds and cotton both white ; and G. nigrum {Ham.):
seeds black, cotton white. G. Barbadense, which is said to be the “ Sea Island
Cotton,” is referred to the latter.

Calyx 5-cleft, without an involucel. Ovary 5-many-celled, with 3 (or rarely
more) ovules in each cell. Capsule composed of 5 or more 2-valved 3-

Peduncles axillary, solitary or rarely in pairs, 1-2- or many-flowered; sometimes
(by the abortion of the upper leaves) in terminal racemes.

Waste places and road-sides: introduced. July-Sept.— (X) Stem 2-5 feet
high, with spreading branches. Leaves deeply cordate, 4-6 inches in diameter,
with a slender abrupt aeumination. Flowers usually solitary on axillary
peduncles, sometimes 3 or more on short flowering branches which bear 1
or 2 small leaves. Corolla orange-yellow. Capsules large, the long beaks of
the carpels spreading in a radiated manner.

son, Arkansas, Dr. Leavenworth ! — If Stem l }-2 feet high, somewhat
branched. Leaves about 2 inches long ; and l i inch wide ; petiole shorter
than the lamina. Capsule subglobose much longer than the calyx: carpels
dehiscing from the summit to the base, partly separating when mature, obliquely
truncate.

above, minutely tomentose. Leaves about an inch long; the petiole half as
long as the lamina. Peduncles several on each branch, arising from the axils
of small abortive leaves, forming a loose raceme. Capsule ovate; the
carpels cohering, except at the summit.
