Small trees produce compound leaves but no branches, i.e. compound leaves attached to the stem. Cream or brown fibrous stripes in the blaze.

Compound leaves with a large number (up to 30 or more) of leaflets. Stipule-like growths produced on the upper surface of the compound leaf rhachis where the leaflets are attached. Leaflet blades about 5-16 x 2-4.5 cm.

Flowers in umbels which are arranged in racemes or panicles. Calyx lobes small. Petals about 2 mm long. Style arms free and divergent following anthesis.

Fruits depressed globular in outline, but conspicuously laterally compressed, about 4-4.5 x 6 x 4 mm, longitudinally ribbed or grooved. Style arms divergent, persisting at the apex of the mature fruit. Embryo very small.

Cotyledons ovate or elliptic, about 5-8 mm long. First pair of leaves simple. At the tenth leaf stage: leaflet blades ovate or linear-ovate, slightly unequal-sided at the base, serrate, glabrous, teeth small; small glands or hairs occur on the rhachis of the compound leaf at the junctions of the leaflet stalks; petioles, stem and terminal bud glabrous. Seed germination time 70 to 152 days.
