Characteristics

Small tree, up to 18 m. Leaves dispersed along the shoots; petiole to 25 cm, striate, with a small basal sheath, the connate stipules forming a small ligule within the petiole; leaflets 5-7, petiolules up to c. 5 cm (the lateral shorter); blade elliptic or oblanceolate, usually c. 10-23 by 2.5-9 cm, gradually tapered to an acute apex, base cuneate, rounded or oblique, margin coarsely dentate or sometimes only finely serrate, glabrous when mature. Inflorescence a panicle of umbellules, often stellate-furfuraceous, with a stout rachis to 40 cm and lateral (secondary) branches which terminate in umbellules, and which commonly bear tertiary branches. Pedicels c. 5-7 mm, with a distinct involucre ('epicalyx') around the base of the flower. Calyx rim undulate or indistinctly dentate, puberulous. Petals 2-3 mm long. Ovary subglobose, c. 2½ mm high.
