Tree of 40 ft., flowering branches stout, terete, glabrous, excepting the hoary-puberulous inflorescence. Leaves 4–3-jugate, 1–1 1/2 ft. long; leaflets subopposite or a short distance apart, thinly coriaceous, oblanceolate or oval-oblong, shortly and rather obtusely acuminate or broadly pointed, rounded more or less and subequal at the base, glabrous, midrib prominent beneath, reticulation rather prominent above and beneath; 6–8 in. long, 2–3 in. broad on stout petiolules of 1/4– 1/3 in. Stipules small. Flowers in terminal stout many-flowered elongating racemes in our specimens 1/2– 3/4 ft. long but probably at length twice as long. Bracts coriaceous, oval or oblanceolate hoary-sericeous externally, glabrate within, imbricate and concealing the unexpanded flowers, deciduous on expansion, 2–2 1/2 in. long. Pedicels stout 1/2– 3/4 in. long ascending. Involucral bracteoles at the base of the calyx-tube, oblanceolate-oblong narrowed below, concave, hoary like the bract and pedicel externally, 2 1/2 in. long. Calyx-tube subglabrous, 1/2 in. long, slightly widening above, limb early deciduous after flowering, segments subequal, linear, acute, reflexed or spreading, exceeding the tube. Petals 5, subequal in length, each with a broad bilobate or emarginate flabellately-veined lamina narrowed rather abruptly into a long winged claw, posterior petal with considerably broader lamina (2–2 1/2 in.), and proportionately shorter claw (3/4–1 in). Stamens all perfect; filaments 2 1/2–3 1/2 in. long, equalling or exceeding the petals, thinly pubescent below, excepting the posterior one very shortly connate at base. Ovary flat with thickened sutures, closely silky-tomentose, on a gynophore, adnate below, 1/3– 1/2 in. beyond the calyx-tube, narrowed above with a slender elongate filiform style equalling the stamens. Ovules 4–6. Legume not seen.
