Plant glabrous apart from leaf-domatia. Stems with yellow wood and exuding yellow sap when cut, bearing prominent cup-like petiole-scars. Leaves: petioles (4-)7-15(-20) cm, swollen at both ends, geniculate at base; lamina usually ovate, elliptic-ovate or broadly ovate, base usually rounded, truncate or slightly cordate, apex abruptly acuminate, (10-)12-25 by (5.5-)8-19 cm, palmately 5-nerved at the base and with 1-3 pairs of lateral nerves usual-ly arising from above halfway along the midrib, main nerves prominent, especially below, both surfaces usually drying matt with a rather obscure reticulum, coriaceous; hollow domatia present on lower surface in the axils of main nerves, with the aperture frequently puberulous. Inflorescences axillary or cauliflorous, paniculate, slender, 10-50 cm, lateral branches spicate or subspicate, 1-5 cm. Male flowers sessile or subsessile subtended by an ovate bracteole c. 1 mm long which is strongly thickened at the base; 3-4 minute outer sepals less than 1 mm long, 3 + 3 larger inner sepals elliptic, ovate or narrowly obovate, 1.5-2.5 mm long; synandrium 0.5-1 mm long. Female flowers (DIELS) with 6 main sepals narrowly oblong with the apex becoming re-flexed, 2.5-4 mm long; staminodes minute, scale-like; carpels 3, 1.5 mm long, stigma broad, sessile, papillose. Infructescences cauliflorous, usually branched, (5-)7-30(-45) cm, with thickened axis and branches, 3-6 mm Ø, the fruits plus carpophores borne on the lateral branches; 1-3 borne together on a club-shaped, unbranched carpophore swollen at the apex, up to 4 cm. Drupes yellow, slightly laterally compressed, transversely subovoid, 2.2-3 by 2.5-3.3 cm (long axis), 2-2.5 cm thick, drying finely rugulose, glabrous; endocarp woody, surface covered with a dense mat of radially arranged fibres.
