A weeping semi-parastic perennial, green shrub to 1.5 m high with soft flexible branches; terete, longitudinally ridged.

Inflorescence of single peduncle bearing many flowers. Flowers white, occasionally flushed reddish-maroon. Flowering between November and January. Fruits are green-brown globose fleshy drupe to 5 mm long; longitudinally ribbed. Seeds are hard brown spherical seeds to 4 mm, with ridges running from end to end. Seed embryo type is linear underdeveloped.
Seed collection and propagation
Collect seeds between November and April. Collect drupes that are maturing; the skin is softens as it ripens. Either collect the drupes from the bushes or collect ripe fruits that have fallen off the plant onto the ground beneath the bushes. Place the drupes in a bucket of water and rub the flesh off with your hands. Drain the water and wash again if required, to remove all the flesh. Then spread the wet seeds on paper towel and leave to dry. Store the seeds with a desiccant such as dried silica beads or dry rice, in an air tight container in a cool and dry place. Seed viability can be average to low. This species is generally difficult to germinate, it has morphophysiological dormancy and complex germination requirements.
