Paramacrolobium

Unarmed evergreen trees. Leaves paripinnate; stipules connate into a +/- elongate, persistent, intrapetiolar scale which is biapiculate to rounded at apex; petiolules twisted; leaflets opposite, in 2-5 pairs, petiolulate, unequal-sided at base, without translucent gland dots. Flowers in compact terminal corymbose panicles; bracteoles 2, well-developed, valvate, completely enclosing flower buds, persistent. Hypanthium shortly cup-shaped. Sepals 4, unequal, posterior one larger than others and 2- toothed at apex. Petals 5, bluish-mauve; upper one relatively very large, 2 lateral ones much smaller, 2 lower ones minute. Stamens 9, their filaments unequally connate at base; normally 3 anticous ones large, well-developed, fertile, and 6 posticous ones reduced, staminodial. Ovary long-stipitate, tomentellous; ovules +/- 6-8; style elongate, glabrous above; stigma abruptly enlarged, reniform-peltate. Pod dehiscing (initially at least along upper suture only) into 2 flattened woody valves without obvious transverse nerves; upper suture with a narrow wing-like ridge along each side. Seeds large, hard, +/- compressed, on short funicles; each side marked with a large areole whose continuous margin is a small but abrupt change in level of surface of seed (areole being slightly sunken in relation to adjacent surface).
