Description: Tree to 30 m high, flowering precociously as shrubs as low as 2 metres.
Leaves paripinnate with 16–37 pairs of linear elliptic leaflets1.5–4.5 cm long, 0.8–1.00 cm wide; gland between proximal (basal) pair, occasionally between distal pairs; stipules linear-attenuate or setiform 4–12 mm long.
Inflorescence terminal, peduncles 1–4.5 (-6) cm; a raceme of 3–16 (-25) panicles , basal panicles at least 5 flowered becoming more depauperate towards the tip; pedicels 13–32 mm; buds globose when young, glabrous or basally puberulent; sepals when mature sub-petaloid, yellow, greenish or brownish, obovate or orbicular, very obtuse, the smaller firmer outer ones 1/2–1/3 as long as the inner, the longest 3.5–8 mm; petals yellow, commonly glabrous dorsally, sometime puberulent along the veins, heteromorphic, the 3 adaxial and 1 abaxial similar (except the latter often larger), obovate-oblanceolate 7–21 mm, contracted into a stalk-like claw, the fifth (abaxial, alternatively right and left up the raceme) sessile, very obliquely semi-ovate or boomerang shaped, coarsely veined commonly largest of all, 14–25 mm long; androecium usually glabrous, filaments of 4 median and 1 lateral-abaxial stamens 0.6–2.3 mm, those of 2 abaxial ones 1.8–9 mm, the anthers of 4 median stamens slightly incurved, at apex truncate or obscurely narrowed into a short neck, the lateral beak 0.3–0.5 mm, dehiscent by 2 parallel slits, the body of 3 abaxial stamens lunately incurved 4.5–9 mm contracted into a porrect, ventrally 2 porose beak 0.8–2.2 mm, ovary glabrous or ciliolate and pilose.
Pods stipitate, broadly linear, obtuse 6.5–20 x 1.3–2.5 cm
Flowering: Late summer early autumn.
Distribution and occurrence: Native of South America, occurring from Colombia to Peru, Bolivia and Brazil. In NSW on the North Coast at Bellingen, this species is most common in a wide unmanaged strip between a road and a pine plantation, but it is also naturalised alongside roads elsewhere in Bellingen and at Thora.
