7 H. Carolinianus Muhl. Herbaceous, glabrous; lvs. cordate, ovate, acuminate, some of them obscurely 3-lobed; ped. distinct from the petiole; petals pubescent inside; caps. hairy inside; sds. hispid. - Wilmington Isl. Ga. (Elliott.) A rare species, apparently lost to modern botanists. Petals purple, 4' long. Caps. globular.

8 H. Syriacus L. Tree Hibiscus. Arboreous; lvs. ovate, cuneiform at base, 3-lobed, dentate; peduncle scarcely longer than the petiole; involucel about 8-leaved. - A beautiful, hardy, free-flowering shrub or small tree, 8 to 15f high. Fls. purple, large. There are varieties with white, red, and striped fls., both single and double. † Syria.

12. ABELMOSCHUS, Medik. Okra. (Arabic Ab-el-mosch, grain or seed of musk; the seeds smell of musk.) Calyx large, spathaceous, i. e., splitting to the base on one side; involucel, column and fruit as in Hibiscus.

1 A. Manihot Medik. Not prickly; lvs. palmately divided into 5 to 7 linear, acuminate, coarsely dentate lobes; ped. and involucel hispid; bracts of the involucel 5 to 7, ovate or lanceolate, acutish, persistent, entire; cal. split on one side; caps. densely hirsute, acuminate.-Malvaceae Mallows Part 4 427 Western States. A beautiful herb, 4 to 5f high. Lvs. cordate, lobes 6 to 10' long, 1/2 to 1 1/2' wide, separated to near the base, about as long as the petioles. Teeth largest near the summit. The fls. are of an exceedingly rich sulphur yellow, purple in the center. Petals 3 to 4' long. Jl., Aug. (Hibiscus, L.)

2 A. esculentus Medik. Okra. Lvs. cordate, 5-lobed, obtuse, dentate; petiole longer than the flower; involucel about 5-leaved, caducous. - Native of W. Indies. Plant herbaceous, 2 to 3f high, nearly glabrous. Petiole with a hairy line on the upper side, nearly 1f in length. Lamina 8 to 10' broad. Fls. 1 to 2' long, on a short peduncle. Petals greenish yellow. The large, mucilaginous pods are used for pickles, or served up with butter. (Hibiscus, L.)

3 A. Collinsiana. Lvs. pedately 5-paried, segm. linear-oblanceolate, coarsely toothed, acuminate, the lowest obtusely 5-lobed; ped. short, involucel 10 to 12-leaved.-Fla., rare. Plant thinly hirsute or hispid. Lvs. 6 to 8' broad. Fls. much as in No. 2. (Hibiscus, Nutt.)

13. GOSSYPIUM, L. Cotton Plant. Fig. 252. (Name said to be from the Arabic, goz, a silky substance.) Calyx obtusely 5-toothed, surrounded by an involucel of 3 cordate leaves, deeply and incisely toothed; stamens very numerous, lateral; stigmas 3, rarely 5, clavate; seeds ∞, involved in cotton. - Fls. yellow.

G. herbaceum L. Cotton Plant. Lvs. 3 to 5-lobed, with a single gland below, lobes mucronate; seeds brownish, cotton white.-Malvaceae Mallows Part 4 428 The species commonly cultivated in the Southern States, and often growing spontaneously. It is an herbaceous plant, about 5f high, sown in early spring and harvested in autumn. Sts. hirsute above. Upper lvs. often but 2 or 3-lobed, lobes commonly acuminate, tipped with a mucro. Petioles about as long as the lvs., peduncles shorter. Fls. handsome, 3' broad, light yellow, with a purple eye, changing to reddish brown. § E. India.

β? Barbadense. Sea Island Cotton. Gland3 on the back of the leaf (mid-vein) 3; sds. black, cotton white.-Malvaceae Mallows Part 4 429 Sown in Sept. and Oct. Cotton long, with a silk-like texture. † W. India. Chiefly cultivated near the southern coasts. (G. Barbadense L.) G. arbdreum is the Tree Cotton of E. India, with red flowers, and G. Peru-vianum, the Brazil Cotton. The Nankin Cotton is another variety of G. herbaceum. Plants so extensively cultivated as the cotton are liable to much variation. Of the thirteen species described by De Candolle, only the three above named are now regarded as genuine - the others considered as varieties. The microscope shows the fiber of cotton to consist of a lengthened and generally flattened cell, thus readily distinguished from the fiber of silk, which is terete and Bolid, or wool, which is imbricate-scaly.
