Unarmed shrub, up to 5 m high; young stems and inflorescences densely covered with blackish stalked glands. Leaves glabrous, up to 200 mm long, occasionally with a few glands. Pinnae 7-15 pairs, opposite, subopposite or alternate, often with a solitary, terminal pinna. Leaflets 7-12 pairs per pinna, oblong-elliptic, usually with black gland dots just inside margins. Inflorescences 60-180 mm long, terminal racemes. Flowers yellow. Calyx: sepals 13-21 mm long, pubescent and with many stipitate glands. Petals 17-32 mm long. Stamens scarlet. Flowering time Oct.-May. Pod asymmetrically oblanceolate-oblong.
Woody shrub, up to 5 m high; stalked glands covering young stems and inflorescences; unarmed. Leaves bipinnate; blade 60-200 mm long, pinna pairs 7-15 opposite, subopposite or alternate, 7-12 leaflet pairs per pinna, leaflet blade elliptic-oblong, 2-8 x 1.0-2.5 mm. Flowers: in terminal racemes; stamens 50-105 mm long, scarlet; petals 17-32 mm long, yellow; Oct.-Dec. Pods light brown, compressed, pubescent, glandular when young, becoming glabrescent with age, dehiscent.
Leaves: petiole and rachis together 8–20 cm, glabrous, occasionally with a few glands; pinnae 7–15 on each side of the rachis, opposite, subopposite or alternate, and often with a solitary terminal pinna; pinna rachis 1–4 cm; leaflets 7–10(12) per pinna, 2–8(11) × 1–2.5(3.5) mm, oblong-elliptic, glabrous, usually with black gland dots just inside the margins.
Pods 6–10 × 1.7–2.1 cm, ± obliquely oblong, straight or somewhat curved upwards, compressed, light brown, pubescent and usually conspicuously spotted with dark glands when young but glabrescent and smooth later, dehiscing down both margins; seeds 5–8, c.9 × 7 × 2.5 mm, ± broadly obovate, compressed, brown flecked with purplish-black.
Racemes 6–16(24) cm long, all terminal; bracts up to 28 × 8 mm, lanceolate to oblanceolate, ± pectinate, conspicuous and concealing the young buds but falling before anthesis; pedicels 1.5–3.5 cm, with stipitate glands.
Lateral sepals 13–21 mm long; all sepals pubescent and usually with numerous stipitate glands, the lower one usually pectinate or erose at the apex.
Young stems and inflorescences pubescent and fairly densely covered with stipitate, peltate, usually blackish or brown glands, without prickles.
Ovary tomentose and with shortly stipitate glands; style somewhat exceeding the stamens.
Stamens 5–10.5 cm long, much exceeding the petals, the filaments bright red.
Shrub or small tree 1–3(5) m high.
Petals (17)23–32 mm long, yellow.
