Erect or spreading shrub to 1.5 m high with branches covered in hairs that lie close along the stem.

Inflorescences with solitary or up to 3 pale yellow to almost white flowers in clusters at branch-tips, closely surrounded by and partly hidden by leaves. Flowers throughout the year. Fruits are green cylindrical capsule surrounded by leaves. Seeds are greenish brown, ovoid to 6.5 mm long and 3 mm wide covered in scattered hairs. Seed embryo type is investing.
Seed collection and propagation
Collect seeds between January and December. Collect capsules that are large and fat. Capsules are difficult to find as it is hidden among the leaves. Place the capsules in a tray and leave to dry for 1 to 2 weeks. Then rub the capsules gently by hand to dislodge the seeds. Use a sieve to separate the unwanted material. 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 is usually low and seed availability can also be very low and difficult to find. This species has morphophysiological dormancy and can be difficult to germinate.
