Shrub or small tree. Branches lanate when young, glabrescent. Leaves with stipules lanceolate,
membranous, caducous; petioles 2–4 mm long, terete, lanate pubescent when young; lamina
oblong, thickly coriaceous, 2–9 × 1–4.2 cm, retuse to rounded at apex, cuneate or subcuneate
at base, glabrous above when mature, with grey-lanate pubescence; primary veins 5–8 pairs.
Inflorescences small terminal and axillary cymules or panicles of cymules 0.5–2.5 cm long;
rachis and branches puberulous. Bracts and bracteoles chartaceous, pubescent, 1–2 mm long.
Flowers 1.5–2 mm long. Receptacle campanulate, grey-puberulous on exterior, tomentose within;
pedicels c. 1 mm long. Calyx lobes acute, grey-puberulous on both surfaces. Petals 5,
glabrous. Stamens 7 or 8, unilateral with tooth-like staminodes opposite. Ovary and base of
style pilose. Fruit ellipsoid, 1.1–1.5 cm long, narrowed towards base; exocarp glabrous; mesocarp
thin and fleshy; endocarp thin, hard, bony, densely lanate-tomentose within. Fig. 38A–E.
