Morphology General Habit

Tree 4.5–30 m. high; crown spreading; bark rough or smooth.

Morphology Branches

Young branchlets densely to very sparsely clothed with minute crisped puberulence, usually soon disappearing but sometimes persistent.

Morphology Leaves

Leaves:pinnae (Fig. 22/6, p. 163) (1–)2–3(–4, even—fide I.T.U. –5) pairs, each pinna broadening towards apex; leaflets of 2 distal pairs of pinnae 2–5 (very rarely 6) pairs, obliquely rhombic to obovate, with the distal pair largest, 29–72 mm. long, 16–43 mm. wide; lower pairs smaller, down to about 12 × 8 mm.; apex obtuse, rarely subacute; base not auricled; surface beneath glabrous except for puberulence on midrib and margins.

Morphology Leaves Stipules

Stipules and bracts at base of peduncles very caducous, narrowly triangular-lanceolate and acute, 2–7 mm. long, 1–2 mm. wide.

Morphology Reproductive morphology Inflorescences

Peduncles clothed as branchlets; bracteoles very caducous, subulate-linear to oblanceolate, 1.75–3 mm. long.

Morphology Reproductive morphology Flowers

Flowers subsessile; pedicels puberulous, 0.25–0.5(–0.75) mm. long.

Morphology Reproductive morphology Flowers Calyx

Calyx 2–4 mm. long, puberulous outside.

Corolla 6–9(–10) mm. long, densely and minutely pubescent or puberulous outside, white or pink.

Morphology Reproductive morphology Flowers Androecium Stamens

Staminal tube red, exserted about 1–1.8 cm. beyond corolla.

Morphology Reproductive morphology Fruits

Pod oblong, flat or somewhat transversely plicate, mostly 10–18 cm. long and 2–4 cm. wide, usually pubescent or puberulous on stipe, otherwise glabrous or nearly so.

Morphology Reproductive morphology Seeds
