An erect semi-parastic, many-stemmed perennial shrub to 3 m high; branches more or less erect, slender, rigid or flexible, angular or ridged. Leaves narrow-deltoid, triquetrous, to 1.5 mm long, the tips and eventually the whole leaf often caducous (deciduous). Inflorescence yellowish, 1-4 mm long, bearing 2-5 flowers but only 1 fruit. Flowers enclosed at the base by 3 brown or whitish ciliate or fimbriate bracts; perianth yellow (brownish when dry), 1-1.5 mm long. Flowering throughout the year. Fruits are green ovoid or almost globular fleshy drupe to 6 mm long. Seeds are hard brown spherical seeds to 6 mm, with ridges running from end to end. Seed embryo type is linear under-developed.
Seed collection and propagation
Collect seeds between December and April. Collect drupes that are maturing; the skin is softens as it ripens. Either collect the drupes from the bush or the easiest method is to collect ripe fruits that have fallen off the plant from on 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. From one collection, the seed viability was low, at 19%. Seeds collected off the bushes tend to be less viable than those collected from the ground. This species is generally difficult to germinate, it has morpho-physiological dormancy and complex germination requirements.
