Tree 2.5–6 m. high; habit gnarled; bark finely to coarsely reticulate-fissured, grey, brownish or black; crown few-branched, flat-topped; foliage pendulous in loose bunches. Stipules shortly connate, linear, ± falcate, 1.5–2 cm. long, caducous; auricle lateral, small, or 0; intrapetiolar stipule-bases persistent, usually prominent, subtending flattened and keeled dormant buds. Leaves glabrous or shortly appressed-pilose throughout, with (4–)5–7(–9) widely-spaced pairs of leaflets, the middle pairs usually the largest; petiole (1.5–)2–5 cm. long, pulvinus prominent, dark; rhachis (13–)15–20(–25) cm. long, channelled; stipellar expansions usually obscure or absent; leaflets oblong to narrowly ovate, rarely falcate, (2–)3–11 × (1–)2–3(–4) cm., obtuse or acute to acuminate, obliquely truncate-subcordate to rounded-cuneate at base; midrib subcentral; basal fanwise nerves (2–)3–4; lateral nerves slender, rather close; surfaces closely but often obscurely reticulate. Panicles terminal and axillary, 5–10 × 4–7 cm., ± densely puberulous. Flowers rather large; bracteoles (6–)7–9(–11) × 5–6 mm. Tepals 4–6(–8), free or some connate; outer broadly imbricate, 1.5–3 × 1–3 mm., densely and usually long-ciliate; inner 0 or 1–2, linear. Stamens ± 10, free, filaments 9–11 mm. long; disc-glands usually prominent. Ovary 3.5–5 × 1–1.5 mm., margins crispate-setose. Pod woody, up to 16 × 4 cm., maturing pale brown, thin, becoming densely scurfy very early; sutural wings thin, each 6–8 mm. wide. Fig. 35/12, p. 160.
