Leaflets 2 or 3 on each side, (6–)8.5–10 by 1.8–3.5 cm, the most apical larger, up to 18 by 6.5 cm, elliptical to elliptical-obovate, chartace-ous to subcoriaceous, glossy on both surfaces, ± glabrous; apex markedly acuminate, acumen to 1.5 cm long; base weakly asymmetric, cuneate; major veins not clearly dis-tinct from secondary ones, particularly adaxially, together some 20–30 on each side, parallel, straight, at about 60° to midrib, anastomosing at margin, prominent on both surfaces, rarely with domatia in axils adaxially; petiolules c. 4–6 mm long, weakly swollen and channelled. Spikes or panicles to 15 cm; peduncles very sparsely pubescent; bracts 2 mm long, acute, usually with a pair of smaller bracteoles, all sparsely pubescent. Calyx lobes 1–2 mm long, orbicular, margin ciliate. Petals to 2.5 mm long, yellow, ovate to obovate.
