Annual or perhaps short-lived perennial herb or softly woody shrublet. Stems terete, pubescent with crisped hairs. Leaves paripinnate, 3.5-10 x 1-2 cm; stipules 5.5-8.5 x 1.2-2 mm, narrowly triangular, apex long-acuminate, base asymmetrically auriculate, glabrous; petiolar gland single, 0.7-1.1 mm in diameter, circular, sessile, just below the first leaflet pair; rachis weakly channelled above, sparsely ciliate on the channel margins and crisped pubescent beneath; leaflets in 25-36 pairs, 7.3-10.2 x 1.4-2.3 mm, narrowly oblong, almost straight, asymmetric, base asymmetric, proximal side rounded, distal side rounded-cuneate, apex mucronate, margins shortly ciliate or glabrous, usually glabrous on both surfaces; midrib excentric; 4-5 lateral nerves from base on proximal side, 1-2 on distal side. Inflorescences markedly supra-axillary, 2-3-flowered; pedicels 6-7 mm long in flower, 1.2-1.3 cm long in fruit, pubescent with both crisped and spreading hairs. Sepals 6.5-7.2 x 1.2 mm, narrowly ovate, acuminate, pubescent with crisped hairs outside. Petals yellow, 6-8 x 6-8 mm, broadly obovate to suborbicular. Stamens (7)8-9, with 3-4 longer than the rest; a small staminode sometimes present. Ovary 3.2-4 mm long, densely appressed-pubescent, distally glabrous; stigma terminal, ciliate-margined. Pods 5-6.3 x 0.3-0.5 cm, sparsely appressed-pubescent. Seeds pale yellow-brown with faint darker spots, 2.5-3.2 x 1.6-2 mm, rhomboid, flattened.

Annual herb, producing arcuate-spreading branches to form a frond-like mature plant, subwoody below, 0.1-1.0 m high. Leaves: petiolar gland sessile, never sunken, widely elliptic to oblong, concave above, reddish brown with a darker centre and dark brown when dry. Leaflets sessile in (15-)20-37 pairs, linear oblong, base oblique, apex acuminate to mucronate. Inflorescences (1-)3(4)-flowered racemes. Petals usually not exceeding sepals, pale yellow. Stamens 8 with up to 2 staminodes may be present. Pod valves are greyish white-strigose. Seeds testa shiny.
Annual herb, up to 0.9 m high. Stems erect, rootstock absent. Leaves with blade linear to linear-oblong, 40-70 x 8-15 mm, leaflets in 20-37 pairs, linear-oblong, 4-10 x 0.9-2.3 mm; petiolar gland sessile, projecting from petioles; rachis channelled adaxially with margins of channel ciliate. Flowers: inflorescences 1-4-flowered; petals pale yellow; Dec.-Mar. Pods 30-60 x 4.05.5 mm.
