Much-branched shrub or small tree to 3.5 m high. Branches stout, rigid, more or less spreading; cylindrical or flat-ribbed and stellate-hairy when young. Leaves reduced to ovate caducous scales less than 1 mm long. Inflorescence in short dense sessile spikes or clusters, 2-4 mm long with tiny yellow-green flowers. Flowering between August and December. Fruits are fruit consists of two parts, fleshy, cream turning red pedical (top part) and black ovoid to globular nut (bottom part). Seeds are woody brown globular seed with a fleshy orange aril at tone end. Seed embryo type is linear underdeveloped.
Seed collection and propagation
Collect seeds between October and January. Collect maturing fruits, the top aril is large, succulent, orange to red and bottom bit is hard and black. Leave fruits to dry and harden before storing. Fleshy aril can be removed but it can be stored with the seed. 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. Predation of seeds can be high, however, seed viability is also high. From one collection, the seed viability was high, at 100%. This species is generally difficult to germinate, it has morphophysiological dormancy and complex germination requirements.
