Rigid shrub to 150 cm high, with young branches red-brown and older stems grey. Leaves lanceolate to 12 mm long and 4 mm wide, with acute tip and obtuse base; margins and surfaces covered in fine hairs. Inflorescence in clusters with small pale-pink flowers. Flowering between August and October. Fruits are fleshy reddish globular seeds to 3 mm diameter, easily splitting to form 4 or 5 wedge seeds. Seeds are pale-brown wedge-shaped seed with a wrinkled surface, to 2 mm long and 1.5 mm wide . Seed embryo type is linear underdeveloped.
Seed collection and propagation
Collect seeds between October and January. Lift branches carefully to locate the fruits. Collect berries that are reddish and soft, with a hard seed inside. Place the berries 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 some 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. From one collection, the seed viability was high, at 100%. This species is generally difficult to germinate, it has morpho-physiological dormancy and complex germination requirements.
