Description.

Geoxylic suffrutex with procumbent, annual, branched, longitudinally striate stems to 60 cm, arising from an elongate subterranean axis, glabrous or pubescent. Leaves: petiole 0.8-1.6 cm long, glabrous or pubescent; rachis (1-)3.5-8.5(-13) cm long, grooved above, glabrous or pubescent; pinnae (2-)5-10 pairs per leaf, 1.8-6 cm long, with 12-28 pairs of leaflets; leaflets 2.5-6(-9) × 1-1.8(-2.25) mm, linear to linear-oblong, apex acute to obtuse, sometimes asymmetric, mucronate, base oblique, mid-rib running from distal corner of leaflet base to apex centre, lamina glabrous. Inflorescence: an axillary spiciform raceme, 4.5-9.5 cm long, usually solitary, rachis glabrous to densely pubescent. Flowers: yellowish-white, pedicels 1.25 mm long and articulated near the middle, with minute glands at the base; calyx 1.5 mm long, shallowly toothed, glabrous; petals 3.25 × 1.25 mm; stamen filaments 6 mm long. Fruit: a laterally compressed falcate craspedium, 9 × 3.2 cm, transverse veins prominent, lacking transverse septa between seeds, the valves thus separating from the replum intact upon ripening, the epicarp of both valves peeling away from the endocarp; umbonate over seeds. Seeds: mature seeds not seen.
