Leguminosae, J. B. Gillett, R. M. Polhill & B. Verdcourt. Flora of Tropical East Africa. 1971

Morphology General Habit

Large tree, 15–36 m. tall, with long clean bole and small rounded crown; bark smooth, grey or pale brown; slash pale, exuding red gum.

Morphology Branches

Branchlets brownish pubescent to tomentellous, usually soon glabrescent.

Morphology Leaves

Leaves up to 18–36 cm. long; stipules oblong-lanceolate, up to 1 cm. long, caducous; lateral leaflets 3–5 on either side, elliptic-oblong to elliptic-ovate or ovate, 6–14 cm. long, 2.8–7 cm. wide, the lower ones relatively shorter and broader, rather abruptly contracted to the narrow mucronate generally pronounced acumen, broadly rounded to cuneate at base, subglabrous, usually minutely glandular beneath, with 6–10 well-spaced fine curved-ascending primary lateral nerves looped near the margin and laxly reticulate prominulous venation.

Morphology Reproductive morphology Inflorescences

Racemes or little-branched panicles axillary, but sometimes aggregated terminally or on short lateral branches into pseudopanicles, 5–15 cm. long; axes thinly pubescent to tomentellous; bracts linear to oblong-lanceolate, acuminate, 3–12 mm. long, evanescent; bracteoles near top of the 3–6 mm. long pedicel, elliptic to oblong-lanceolate, 3–8 mm. long, caducous.

Morphology Reproductive morphology Flowers Calyx

Calyx 5–8 mm. long, mostly subglabrous but densely covered with short hairs near lobe-margins outside and on the lobes inside.

Morphology Reproductive morphology Flowers Corolla

Corolla 10–16 mm. long, golden-yellow; standard ovate-elliptic to suborbicular, usually emarginate; wings not much longer than the keel and nearly as long as the standard.

Morphology Reproductive morphology Fruits

Fruit obovate-orbicular, 10–12 cm. long, with a 0.6– 1.2 cm. long stipe and a very broad membranous glabrous wing bearing the style to one side, not much thickened over the seed-cavity, laxly venose but prominently so only over the seed-cavity and towards the style-base.
