Shrub or small tree to 5 m tall, trunk mottled grey.
Leaf blades glabrous, about 3-9 x 1.1-3.7 cm, margins serrate to serrulate. Lateral veins not forming distinct loops inside the blade margin, 8-14 pairs; apex mucronate to obtuse. Reticulate veins quite prominent and raised on surface. Petiole quite short, about 1.5-4 mm long, +/- ridged on the upper surface, glabrous.
Inflorescence a many flowered cyme. Flowers 5-merous. Sepals rounded to ovate, and concave, entire or erose, 1-1.5 mm long. Petals oblong-obovate to rounded, concave, 2.5-4 mm long, cream to pale yellow. Staminal filaments 1.2-1.8 mm long, fused near the base forming a ring around the ovary. Ovary mostly exposed above the disk, imperfectly 3 (rarely 2-4)-locular with 2-4 ovules per locule. Style about 1.2-1.7 mm long. Stigma very shortly 3-lobed at the apex.
Fruit a capsule, 1.6-2.5 long when mature and to 1.4 cm wide prior to dehiscence, ripening yellow to orange, valves woody, 1-2 mm thick. Seeds about 3-6 x 3-4 mm mostly completely enclosed in the large fleshy aril. Cotyledons more or less orbicular, much wider than the short radicle.
