Shrub or small tree to 6 m high; bark pale grey to whitish, finely longitudinally furrowed. Young stems hairy with appressed pale brown hairs and ± angular, stems becoming hairless.


Leaves simple, alternate. New growth reddish. Stipules absent. Petiole 3-7 mm long. Leaf blade narrow-elliptic or lanceolate, 4.5-18.5 cm long, 0.6-1.2 cm wide, base attenuate or cuneate, margins entire, recurved, apex bluntly acute or obtuse. Lateral veins 26-35 pairs, intramarginal vein present. Domatia absent. Upper surface green, glossy and hairless, lower surface yellowish green and sparsely hairy. Two to three (sometimes more) widely spaced, small, flat glands visible on the underside of the leaf blade between the midrib and each margin.


Inflorescences axillary, flowers solitary or in few-flowered clusters. Flowers bisexual, actinomorphic, 4- or 5-merous, cream, yellowish, occasionally red or tinged red. Pedicels 1-4 mm long. Sepals imbricate, fused only shortly at base, lobes c. 1 mm long, pedicel and sepals hairy. Petals free, lobes c. 2.5 mm long, concave, glabrous or slightly hairy on outer surface. Stamens 8 or 10 (twice the number of petals), filaments more or less free, flattened with stamens alternating with petals up to twice as wide as those opposite petals, hairy on margins and inner surface for upper two thirds. Disk present beneath 5 (usually), apparently free carpels, superior, densely hairy; styles united; stigma solitary.


Fruit fleshy, consisting of 1-4 (usually 2), drupe like units (mericarps), each developing from a separate carpel, each unit ± ovoid, 8-12 mm long, hairy, ridged, sometimes appearing flattened and winglike towards apex, disk persistent at base. Stone or endocarp solitary in each mericarp, usually 1-seeded.
