Usually flowers and fruits as a shrub 1-2 m tall.
Leaves arranged distichously on twigs so that each twig resembles a compound leaf. Stipules broadly triangular, small but persistent, about 1-2 mm long. Leaf blades about 25-40 x 15-23 mm. Lateral veins forming fairly distinct loops inside the blade margin. Leaves do NOT emit an obnoxious odour when crushed.
Flowers about 1-1.5 mm diam. at anthesis. Male flowers: Flowers with sessile anthers, fused to one another to form a staminal column in the centre of the flower. Female flowers: Flowers with a perianth that resembles an eggcup with the gynoecium enclosed like an egg in an eggcup. Style fleshy and swollen.
Cotyledons elliptic to obovate, about 8-10 x 4-5 mm. At the tenth leaf stage: leaf blade with a very small mucro at the apex, leaves arranged distichously on lateral shoots so that each lateral shoot resembles a compound leaf. Stipules triangular, about 0.5-2 mm long. Seed germination time 63 to 65 days.
