Characteristics

Trees (2.5-)3.0-4.0(-9.0) m high; single stemmed, diameter (120-)220-250(-300) mm; cork dark grey-brown, fissured, rough, tessellate; young stems and growing points glabrous or sparsely white-pubescent. Leaves palmately compound with 3-5 pinnae; petiole (14-)23-38(-49) mm long, glabrous or [as “of”] sparsely white-pubescent; petiolule (0-)4-7(-12) mm long, sparsely pubescent; median pinna (31.5-)51-74(-99) x (17-)21-29(-48) mm, elliptic, narrowly ovate or narrowly obovate, yellow-green to khaki or dark green, base acute, apex acute, shortly acuminate or rounded, margin entire or toothed in the upper half, adaxial surface glabrous, occasionally sparsely pubescent and glandular, abaxial surface pubescent and glandular, chartaceous. Inflorescence a compound dichasium, total length (33-)56-83(-120) mm, white-pubescent; length of bracts at first branch of inflorescence (4-)9-13(-19) mm. Flowers with total length 6-10 mm, regular. Calyx 5-lobed, lobes 1.5-3.5 mm long; tube 3-4 mm long; external surface glandular pubescent, internal surface glandular. Corolla: tube straight 6-9 mm long; lobes 5, front view of lobes 10.0-11.0 x 6.0-6.5 mm, situated at right angles to tube; tube white, lobes mauve. Androecium didynamous, longest pair of stamens 6 mm and shortest pair 5 mm, exserted. Ovary globose or obovoid, hairy and white glandular in upper half; style 6-9 mm long. Fruit dry, obovoid, 3 x 4 mm, sessile in base of a persistent, chartaceous, campanulate calyx.

Perennial tree, 3-4 m high; single stemmed; young stems and growing points glabrous or sparsely white-pubescent. Leaves palmately compound with 3-5 pinnae; pinnae narrowly ovate or narrowly obovate, apex acute, base acute, shortly acuminate or rounded, margins entire or toothed in upper half; upper surface glabrous, occasionally sparsely pubescent and glandular; lower surface pubescent and glandular, chartaceous; petioles glabrous or sparsely white-pubescent, petiolules sparsely pubescent. Inflorescence a compound dichasium. Flowering time Nov.-Jan.
Leaves (4)5-foliolate, petiole 3–5 cm long, grooved at the base; median petiolules 0.3–1 mm long; leaflets 6–10 × 2.5–4 cm, elliptic, narrowly ovate to narrowly obovate, rounded and shortly acuminate to acute at the apex, cuneate at the base, entire, drying dark green and somewhat darker above, sparsely pubescent or glabrous and gland-dotted above, pubescent and gland-dotted beneath, nerves raised beneath.
