Description.
Shrub or small tree to 10 m tall or liana to 12 m, stem to 20 cm thick, often twisted (Fig. 10A View Figure 10 ). Leaves: rachis 8-16 cm long, grooved above, glabrous; pinnae (2-)3-5(-8) pairs per leaf, (4.5-)5.2-8.9(-13) cm long, with 10-17(-21) pairs of leaflets; leaflets 13-19(-29) × (3-)4.9-5.5(-10) mm, oblong to obovate-oblong, apex rounded, base asymmetric rounded on proximal margin and cuneate on distal margin, mid-rib diagonal and raised above and below, lamina appressed-pubescent to glabrous (Fig. 10B View Figure 10 ). Inflorescence: an axillary spiciform raceme, 4-12(-13.5) cm long, usually clustered, but sometimes solitary, rachis pubescent or glabrous (Fig. 10C View Figure 10 ). Flowers: white to yellow, pedicels 1-1.5 mm long, with an unpleasant odour; calyx obconical, 1-1.5 mm long, glabrous to sparsely pubescent, distinctly toothed; petals 3-4 × 1-1.4 mm; stamen filaments 4-6 mm long. Fruit: a torulose, laterally compressed, slightly curved craspedium 20-45 × 5-10 cm, with transverse septa between seeds dividing the fruit into one-seeded segments which, upon ripening, fall from the persistent replum (Fig. 10D, E View Figure 10 ). Seeds: elliptic, 14-17.7 × 10.5-12.8 × 3.3-4 mm, pleurogram elliptic, open near hilum.
