Plant description

Dense shrub or tree to 8 m high with larger spreading or erect, scabrous branches; smaller branches slender, green, pendulous, furrowed. Leaves persistent only on branchlets, reduced to minute spreading triangular or lanceolate scales usually 1-2 mm long. Inflorescence sessile, in short pedunculate spikes, usually only 1 in each spike; fertile, with tiny yellow-green flowers. Flowering between October to May. Fruits are fruit consists of two parts, fleshy, red pedical (top part) and deep red ovoid to globular nut (bottom part). Seeds are woody brown globular seed to 5 mm long and 4 mm wide with a fleshy orange aril at one end. Seed embryo type is linear underdeveloped.

Seed collection and propagation

Collect seeds between January and June. Collect maturing fruits, the top aril is large, succulent, orange, pink or red and bottom bit is hard and red. 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. This species is generally difficult to germinate, it has morphophysiological dormancy and complex germination requirements.
