Harms, H.A.T. in Engler, H.G.A. & Prantl, K.A.E. (1894) Die Naturlichen Pflanzenfamilien 3(8): 45.
Usually flowers and fruits as a shrub about 3-4 m tall.
Strong curry powder odour from dried twigs, petioles and leaves. Compound leaves up to 80-100 cm long with 10-17 leaflets. Base of the compound leaf petiole clasping the twig. Two narrow wings extend from the base of the compound leaf petiole for about 5-6 cm along the upper surface of the petiole forming a trough or valley. Leaflet blades often quite large, about 16-28 x 8-11 cm. Stalk of the terminal leaflet much longer than those on the lateral leaflets. Terminal buds glabrous. 'Stipules' decurrent, about 6-7 cm long, attached to the base of the petiole. Leaflet stalks about 1.5-2 cm long, deeply channelled on the upper surface. Lateral veins about 8-10 on each side of the midrib.
Cotyledons ovate, about 9-14 x 9 mm, apex obtuse, usually retuse, base cuneate, glabrous. First pair of leaves ovate with fine teeth at least in the upper half. At the tenth leaf stage: leaflets ovate or lanceolate, apex acuminate or acute, base cordate, obtuse or oblique, margin serrate, midrib raised on the upper surface. Petiole, rhachis and petiolules grooved on the upper surface. Most plant parts produce a clear or slightly cloudy meagre exudate when cut. Stipules and the base of the petiole fused, difficult to distinguish. Base of the petiole clasping the stems and expanded into a narrow wing on each side and extending about 1-1.5 cm along the petiole. Seed germination time 27 to 42 days.
