A slender vine not exceeding a stem diameter of 2 cm.

Leaves

Twigs and petioles produce a milky exudate. Leaf blades about 5.5-7.5 x 2.5-4 cm, petioles about 0.6-1.5 cm long. About 4-10 colleters (small finger-like glands) present on the upper surface of the midrib near its junction with the petiole. Lateral veins form a definite series of loops inside the blade margin. Reticulate veins appear to 'flow' outwards towards the leaf blade margin.

Flowers

Inflorescence axillary, umbelliform. Flowers about 2-3 mm diam. Sepals about 1-1.5 x 1 mm. Corolla tube about 1 mm long, lobes about 1 mm long. Corolline corona about 1 mm high, consisting of 5 rounded bulges. Staminal corona absent. Pollen aggregated in +/- erect pollinia. Carpels about 0.5 mm high, ovules numerous in each carpel.
