Description.

Shrub to small deciduous tree 1-4(-7) m tall, young shoots often becoming blackish (Fig. 15A). Leaves: petiole 1-5(-7.5) cm; rachis 6-20(-45.5) cm, grooved above; pinnae 3-30(-41) pairs per leaf, 1.8-9 cm long, with 9-40(-48) pairs of leaflets; leaflets 3.5-12(-22) × 0.7-0.8(-2.75) mm, linear-oblong to narrowly oblong, apex acute to rounded and mucronate, base oblique, mid-rib running from distal corner of leaflet base to apex centre, lamina glabrous (Fig. 15B). Inflorescence: a spiciform raceme, (2-)5-20(-23) cm long, axillary, solitary or aggregated in fascicles or on short lateral shoots, rachis glabrous (Figs 2H, 15C). Flowers: yellowish-white, sometimes tinged pink or purple, pedicels 1 mm, articulated near the middle, with minute pale yellowish-white glands at the base of the pedicels; calyx 1.5-1.75 mm long, distinctly toothed, glabrous; petals 2.5-3 mm long; stamen filaments 4.5 mm long (Fig. 15C). Fruit: a straight to curved craspedium, (15-)20-30(-44) × 1.3-2.2(-3) cm, lacking transverse septa between seeds, thus leaving the valves to separate from the replum intact upon ripening, the epicarp exfoliating from the endocarp; umbonate over seeds (Fig. 15D). Seeds: ellipsoid to lenticular, 11-20 × 9-18 × 7-12 mm.
