Anacolosa Blume

Trees or erect shrubs (none scandent in Mal.). Leaves spiral, sometimes sub-distichous, penninerved. Flowers in sessile (very rarely peduncled) cymes or fascicles, often from bracteolate woody warts or short axes, rarely from trunk or stem, bisexual. Calyx cupular, very shortly (5-) 6 (-7)-dentate, or subtruncate, not enlarged after anthesis, subpersistent at base of the mature fruit. Petals (5-) 6 (-7) inserted on the margin of the cupular disk, fused in the lower part, fleshy, concave below and including the stamens there, with a bearded keel above the cavity. Stamens (5-) 6 (-7); filaments short, flat; anthers broad-ovoid, the cells distant and immersed in the thickened connective, the latter generally with a long-hairy top. Disk hypogynous, adnate to the ovary, much accrescent in fruit, 6-denticulate or-furrowed. Ovary with its base or for a greater part immersed in the disk, incompletely 2 (-3)-celled below, 1-celled above, with a central basal placenta bearing 2 (-3) unitegmic ovules pendent from its apex; style short, with a thickened or conical base; stigma very shortly lobed. Drupe included by the enlarged disk almost to the top, and tipped by the remains of the style at the base subtended by the persistent calyx; pericarp thin-fleshy; endocarp thin-crus-taceous. Seed 1; embryo minute, at the apex of the fleshy albumen which contains starch and oil.

Usually in lowland forest, rarely in montane rain-forest.
