Geoxylic suffrutex with erect annual 5-120 cm stems, young stems densely pubescent (Fig. 8A View Figure 8 ). Leaves: petiole 6-12 cm long, grooved above, puberulous; rachis 4-17 cm long, grooved above; pinnae 2-4 pairs per leaf, 7.5-14 cm long, with 6-13 pairs of leaflets; leaflets (1.2-)2-3.5(-4) × 0.7-2 cm, narrowly oblong to obovate-oblong, apex rounded to emarginate, base asymmetric, rounded to cordate on proximal margin, cuneate to cuneate-rounded on distal margin, lamina pubescent below at least on mid-rib and often throughout (Fig. 8A, B, D View Figure 8 ). Inflorescence: an axillary spiciform raceme 4-12 cm long, 1-3 per axil, rachis usually glabrous (Fig. 8A-C View Figure 8 ). Flowers: pale cream, pedicels 1-2 mm long; calyx campanulate, 1-2 mm long, shallowly toothed; petals 3-4 mm long; stamen filaments 5-6 mm long (Fig. 8C View Figure 8 ). Fruit: a torulose, laterally compressed, straight to distinctly falcate craspedium, 7.5-22 × 1.5-6 cm, with transverse septa between seeds dividing the fruit into one-seeded segments which, upon ripening, fall from the persistent replum (Fig. 8D View Figure 8 ).
