Dioecious tree. Leaves spirally arranged, entire, penninerved. Inflorescence axillary, generally solitary, the one-bracteate peduncle with several dichotomously branched distal branches, each branchlet with a several-flowered compact cyme of sessile small flowers, which are articulated at the base of the calyx. Calyx cup-shaped, shortly 5(-6)-dented. Petals 5(-6), valvate, apex minutely inflexed, shorter in the ♀ flower. ♂ Flowers: Stamens 5(-6), exserted; filaments filiform, glabrous; anthers versatile, the cells oblong, slightly diverging below, dehiscing introrsally. Rudiment of ovary present. ♀ Flowers: Staminodes 5(-6); filaments shorter than ovary; anthers much reduced in size, cells empty. Ovary subcylindric (upper part curved and contracted), with a lateral oblong swelling; stigma disk-like, obscurely 3-lobed. Drupe oblong, attenuate upwards, flattened, slightly curved; sarcocarp thin; endocarp thin, hard, with 3-5 (or more) ridges running the length of the convex surface, and a longitudinal mediane furrow, i.e. the funiculus with a pair of woody ribs on either side of the funiculus on the concave surface, both funiculus and ribs surmounted by an oblong fleshy appendix extending over the whole length of the fruit, or even surpassing it a little. Seed 1, with copious endosperm and a minute embryo.
