Can grow into a tree-top vine but often flowers and fruits as a shrub about 2-3 m tall. Vine stem diameters to 9 cm recorded.

Leaves

Leaf blades about 0.8-6.5 x 0.6-3 cm, produced on lateral shoots which resemble compound leaves. Leaves tend to be alternate and not spirally arranged on the twigs. Petioles about 0.5-5 mm long, slightly swollen and transversely wrinkled. Venation not always obvious. Stipules linear or narrowly triangular, about 1-2 mm long, margins minutely toothed.

Fruit

Fruits, about 5 x 6-7 mm, on slender pedicels about 5-7 mm long. Perianth lobes very small, persistent at the base of the fruit. Style and stigmas persistent at the apex of the fruit. Cotyledons more than twice as wide as the radicle.

Seedlings

Cotyledons obovate, about 4-6 x 2-3 mm. First pair of leaves rather similar to the cotyledons. At the tenth leaf stage: leaves arranged on short shoots which resemble compound leaves and the individual leaves resemble leaflets. Leaf blade about 7-9 x 3-4 mm, glaucous on the underside. Stipules filiform, less than 1 mm long. Seed germination time 25 to 31 days.
