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.

Distribution There are a few, truly wild, indigenous species in the warmer parts of North and South America, but none re- ported from Panama.
