|
Herbs, shrubs or small trees, the stem and branchlets glabrous to densely pu- bescent, black-punctate with oil glands throughout. Leaves petiolate, the blade entire to usually 3- to 9-palmatilobed, the midvein and often also the principal, lateral veins bearing a dorsal gland (extrafloral nectary) near the base. Flowers axil- lary, solitary, pedicellate; epicalyx normally of 3 distinct or more or less united bractlets, these large, foliaceous, deeply incised-dentate and persistent, or very small, entire and caducous; calyx relatively small, cupuliform, truncate to, 5-denticulate, persistent; petals 5, obovate, adnate to the base of the staminal tube, whitish, or yellow and often with a large, red or purple spot near the base, or purple, or red; staminal tube elongate but shorter than the corolla, the anthers very numerous, hippocrepiform; ovary 3- to 5-locular, the, locules few- to many-ovulate; style un- branched and clavate, rarely divided at the tip, stigmatose apically. Capsules ovoid to subglobose, loculicidally dehiscent, the pericarp chartaceous to coriaceous, be- coming dry and brittle; seeds numerous, commonly obovoid, often angulate, cov- ered with lint (long, unicellular hairs) or with fuzz (a shorter indumentum) or with both, rarely nearly glabrous, exalbuminous; cotyledons plicate, black-punctate.

Note
|
To this genus belong the cultivated cotton plants. Many species have been described, but these, for the most part, probably represent only individual variations, often resulting from interspecific hybridization.
