Characteristics

Large shrub or tree, 4.5–10(–21) m. tall, laxly branched and with ± spreading crown; bark grey or brown, ultimately rough and flaking in small pieces.. Branchlets with a persistent or evanescent yellowish or off-white matted tomentum or practically glabrous.. Leaves 10–30 cm. long; stipules oblong, up to 8–15 mm. long, caducous or rather persistent; lateral leaflets 4–8(–9) on either side of rhachis, elliptic-lanceolate to ovate or elliptic-oblong, 3–7.5 cm. long, 1.5–3.5 cm. wide, bluntly pointed, broadly cuneate to rounded or cordate at base, glabrous to tomentose; lateral nerves ± 6–10 on either side of midrib, ultimately prominulous above.. Panicles produced in profusion from precocious to full-leaf stage, much branched, spreading, ± 5–13 cm. long, many-flowered; axes often with indumentum grading from tomentose on peduncle to subglabrous on pedicels, but sometimes sparsely hairy or glabrous overall; bracts linear-lanceolate to oblong or oblong-oblanceolate, 1.5–3 mm. long, fugaceous; bracteoles, at top of 2–4(–6) mm. long pedicel, oblong to broadly elliptic, 1–2 mm. long.. Calyx 3.5–4.5(–5) mm. long, reddish, glabrous.. Corolla 5–7.5 mm. long, white or cream, turning yellowish, fragrant; standard oblong-obovate to obovate or broadly elliptic with a well-developed claw, glabrous; petals all practically the same length.. Stamens (8–)9–10, united or very rarely in 2 phalanges.. Fruit oblong, narrowed to the pointed or shortly rounded apex, narrowed to the ± 0.8–1 cm. long stipe, 6–11 cm. long, 1–2 cm. wide, papery, reddish-brown, glabrous, obscurely veined, 1–3-seeded.
More
Leaves 14–26 cm long; petiole 2–5.5 cm long, rachis 8–18 cm long; petiolules 3–6 mm long; leaflets (3)4–6(7) on each side of the rachis, occasionally subopposite, 2–6(8) × 1.5–3.5(4) cm, ovate to oblong-ovate or elliptic, obtuse or acute at the apex, broadly obtuse or cuneate at the base; lateral nerves in 4–7 pairs, reticulation on both surfaces scarcely visible; stipules 8–12 mm long, elliptic, acute, falling very early.
Pod 1–3-seeded, flat, thin, 3.5–8(10) × 1–1.5 cm, coriaceous, slightly impressed-reticulate or smooth, slightly thickened and blackish over the seeds, rounded or obtuse to acuminate-acute at the apex, narrowly cuneate or narrowed at the base; stipe 6–10 mm long.
Standard subcircular to obovate, claw 2 mm long; wings as long as the standard, obovate, with auricle rounded and claw 2 mm long; keel petals broader than the wings, dorsally slightly connate at the apex, with auricle subacute and claw c.3 mm long.
