Inflorescence up to ca. 80-flowered, a raceme or occasionally a few-branched panicle, 60–205 mm long; bracts triangular or lanceolate, 2.5-7mmlong, 1–1.5mmwide, pubescent,_at right angles to rachis and much longer than buds before dehiscing; pedicels 3-6 (rarely 8) mm long, puberulent with golden hairs; bracteoles ovate or triangular, 1-1.25 mm long, 0.3 mm wide. Flowers: calyx 3-4mm long, green or purplish-brown; standard broadly orbicular, 10-12.5 mm long (including claw 1.5-2 mm long) and 8-11 mm wide, bright pink with green nectar guides; wings oblong or oblong-ovate, 10-11 mm long (including claw 2-3mmlong) and ca. 3mmwide, bright pink; keel asymmetrically oblong, 9-10 mm long (including claw 3-4 mm long) and 3-3.5 mm wide, pink; filaments up to 9 mm long; anthers cordate, ca. 0.75 mm long and 0.5 mm wide, a few hairs at base; disc 0.3-0.5 mm high; ovary 5-6 mm long; stipe absent or ca. 0.25 mm long

Cotyledons at or close to ground level, fleshy, without venation. First few pairs of leaves usually simple, cordate. At the tenth leaf stage: leaflets broadly ovate, apex acuminate, base obtuse, glabrous on the upper surface; leaflet stalks transversely wrinkled; petiole and rhachis of compound leaf glabrous; stipules hairy, about 3 mm long, oblong, somewhat falcate, apex rounded. Taproot somewhat swollen. Seed germination time 9 to 107 days.

Occurs in CYP, NEQ and CEQ. Altitudinal range from sea level to 500 m. Grows in a variety of habitats, e.g. monsoon forest, fringing forest along creeks, coastal vine thickets, sandstone escarpments, gallery forest, brackish estuaries and on the border of mangrove forest. Often found near permanent fresh water.
