Plant description

Dioecious spreading or sometimes prostrate shrub to 1 m high. Leaves simple, petiolate, obovate; rarely broad-oblong or orbicular, truncate or rounded and irregularly 3, rarely 6-toothed at the apex; to 1.8 cm long and 1 cm wide, viscous, with flat glands, glabrous to sparsely puberulent; margin slightly recurved, undulate, unevenly dentate. Flowers solitary or rarely 2 together,;axillary, with small yellow with red-tipped flowers. Flowering between December and March. Fruits are red-brown capsule, 3-5-angled to 10 mm long and 5 mm wide. Seeds are black ovoid seed to 2.5 mm long and 2 mm wide with orange aril. Seed embryo type is folded.

Seed collection and propagation

Collect seeds between December and April. Collect capsules that contain hard black seeds, usually when capsule is turning red or brown. Place capsules in a tray and leave to dry for 1 to 2 weeks. Then rub the capsules 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 low, at 45%. This species has physiological dormancy that needs to be overcome for the seed to germinate (e.g. nicking the seed coat).
