Botanical Description.--A tree of the second order with leaves 4-5' long, sparse, 5-nerved, heart-shaped, broad, acute, entire, glabrous, 6 small glands on the lower face of the base. Petioles of equal length with the leaves. Flowers large, axillary, solitary. Calyx double, the outer portion deciduous, consisting of 3 small, acute leaflets inserted on the base of the inner calyx; the inner is bell-shaped, larger than the outer, with 5 inconspicuous, persistent teeth. Corolla four times longer than the calyx, of 5 fleshy, fluted petals, their borders overlapping, much broader above. Stamens very numerous, arranged around and along a column. Filaments long. Anthers of half-moon shape. Style 1, very thick. Stigma cleft in 5 parts, which are twisted in spiral form. Seed vessels about the size of a filbert, 5-sided, with 5 apartments each containing 5 ovoid seeds attached by separate seed stalks to the central axis of the ovary. Seeds not woolly. Habitat.--Mandaloya Tayabas, Iloilo. _Gossypium herbaceum_, L. (_G. Indicum_, Lam.; _G. Capas_, Rumph.) Nom. Vulg.--_Algodón_, Sp.; _Bulak_, Tag.; _Cotton_, Eng. Uses.--The root bark is antiasthmatic, emmenagogue, and according to Daruty [4] is a substitute for ergot in uterine hemorrhage. The leaves are used in bronchial troubles and the seeds are sudorific. The negroes in the United States use the root bark in large doses as an abortifacient; but a dose of 60 grams to 1,200 of water in decoction is proper and useful in treating dysmenorrhoea. For a long time the seeds went to waste but industry has learned to obtain from them a brownish-red oil which is used as a substitute for olive oil, from which it is hard to distinguish it, if the latter is adulterated by mixing the two; for both have the same density and a very similar odor and taste. For this reason the production of cottonseed oil is very considerable nowadays. It is cheap and excellent for domestic, industrial and pharmaceutic use. The seeds are used in North America in dysentery and as a galactagogue, and the juice of the leaves as an emollient in diarrhoea and mild dysentery. The pulp of the seeds, after the oil is extracted, yields a sweet material called _gossypose_, which is dextrogyrous and has the formula C_18_H_32_O_16_ + 5H_2_O. The cotton itself, the part used in commerce as a textile, is also the portion of the plant most widely employed in therapeutics; not only the fiber from this species is used, but also that of others that grow in the Philippines, the _G. Barbadense_, L. (nom. vulg. _Pernambuko_, Tag.), and the _G. arboreum_, L. (_Bulak na bundok_, _Bulak na totoo_, Tag.).
