Inflorescences axillary, paniculate, racemose, or spike-like, solitary, sometimes 2 per axil, rarely cauliflorous and fasciculate, mostly spherical in outline, sometimes elongated, sessile, densely flowered; bracts scale-like, mostly persistent, appressed-hairy, often glabrescent; bracteoles caducous. Flowers bisexual. Sepals 4 (or 5), imbricate, reflexed at anthesis. Petals 5 (or 4), narrow, free, glabrous. Stamens (8 — )10( — 15); filaments free, rarely united at the base, usually glabrous; anthers medi-dorsifix, lengthwise dehiscent, in- trorse, usually sagittate below and apiculate at the apex. Ovary usually stipitate and pubescent, 1-4-ovuled (1-, rarely 2-ovuled in Indo-Malesian species). Fruits usually thickened, indehiscent, often flattened especially when young, smooth or rugose, sometimes warty, l(-4)-seeded. Seeds exalbuminous.

Taxonomy

For delimitation of Cynometra and Maniltoa, see the note to the latter genus. This presentation of the genus Cynometra is mainly based on the revisions by Knaap-van Meeuwen (1970) and Verdcourt (1979) as cited above.

Uses

The timber of Cynometra species is not or moderately durable and, consequently, only suitable for interior construction, unless treated with preservative. Several species are treated in
