Trees, probably monoecious. Leaves paripinnate, 4- or 5-jugate (Malesian species); Inflorescences axillary, terminal ones together pseudoterminal, thyrsoid, mostly sparsely branched with divaricate branches, densely hairy like the twigs. Flowers unisexual, actinomorphic or ± zygomorphic, white to cream. Sepals 5, free or nearly so, equal, not petaloid, outside hairy, inside hairy or glabrous. Petals 4 or 5, as long as or slightly longer than the calyx, relatively long-clawed, (sub)glabrous, inside with 2 hairy scales, crested or not. Stamens usually 8, exserted; Ovary slightly 3-lobed, sessile, densely tomentellous, 3-locular, each locule with 1 ovule; Fruits capsular, 3-lobed, not stipitate, smooth, tomentellous, glabrescent or not, not winged, completely 3-celled, loculicidal, inside sericeous. Seeds thick to thin lenticular, completely enveloped by a 2-lobed arillode, the latter without basal extension.
