Erect shrub to 50 cm high with 2 bands of setose to pilose hairs between the nodes of the branchlets. Leaves narrowly obovate to 10 mm long and 1.5 mm wide, obtuse, setose. Inflorescence terminal and axillary in 3-6-flowered cymes with pink flowers. Flowering between September and December. Fruits are pale brown, two to four segmented capsule. Seeds are black ovoid seed to 3mm long and 2 mm wide with a wrinkled surface. Seed embryo type is linear fully developed.
Seed collection and propagation
Collect seeds between November and February. Collect mature capsules, those that are turning a pale straw colour and contain hard seeds. Place the capsules in a tray and leave to dry for a 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. From one collection, the seed viability was high, at 90%. This species has morphophysiological dormancy and can be difficult to germinate.
