Dioecious trees. Leaves spirally arranged, subdistichous, entire, penninerved. Panicles 1-2(-3) per axil, 2-3-chotomized, the branches cymose, peduncled; pedicels short, articulated with the calyx. Calyx cupular, small, obscurely 5-toothed. Petals 5, valvate, lanceolate-oblong, apex inflexed. ♂ Flowers: Flower bud clavate. Stamens 5; filaments flattened and fleshy, rather abruptly narrowed to the connective, at least the ones of the functional stamens bearing few to numerous long-clavate hairs dorsally at the connective and ventrally below the anther; anthers elliptic-oblong, slightly surpassing the connective, the cells diverging below. Ovary rudimentary, with a generally rather distinct lateral swelling. ♀ Flowers: Flower bud cucullate. Staminodes with filaments reduced in size and generally glabrous, the anther cells minute, void of pollen. Ovary subcylindrical, early curved, with a distinct lateral swelling; stigma sessile, umbilicate-subcapitate, lobes 3-5, very short. Drupe oblong to elliptic, rounded-truncate at both ends, or subovate and attenuate upwards, flattened and curved, the concave side with a large oblong pulviniform fleshy appendage superficial to the sarco-carp, the latter rather thin, also filling the groove on the concave side of the tenuous or almost woody thin endocarp, which bears 1-3(-5) prominent longitudinal ridges on the convex and maybe two fainter ones on the concave or flat side. Seed 1; endosperm abundant; embryo apical, minute.
