Leaves odd-pinnate, glabrous, 6-11 cm long; petiole and petiolules canaliculate above; leaflets 3, inserted at the top of the petiole, lanceolate to ovate or elliptic, acuminate apically, narrowed into the petiolule basally, the lateral leaflets inequilateral, the margins crenulate and slightly revolute, the blade pellucid punctate throughout, the marginal punctations at the bases of the crenulations conspicuous, coriaceous, paler beneath, 25-91 mm long, 11-32 mm wide, the terminal leaflets largest. Staminate panicles axillary, branched, minutely and sparsely puberulent, to 4.5 cm long. Staminate flowers green, subsessile or sessile; sepals 4, connate basally, broadly triangular, minutely puberulent, with a large subapical dorsal punctation, the margins hyaline, less than 1 mm long; petals 4, elliptic, with a large subapical dorsal punctation, the margins hyaline and ciliate, imbricate, ca. 2 mm long, 1 mm wide; stamens 4, exserted, 3-4 mm long; carpels 2, connate to the base of the style. Carpellate panicles axillary, branched, minutely and sparsely puberu-lent, 1.5-3.5 cm long. Carpellate flowers like the staminate, except the stamens absent; disc large, conspicuous, 3-lobed; carpels 3, free, obovoid, glabrous, the style ca. 1 mm long, the stigma capitate.
