Plant description
Dioecious, or rarely polygamous-dioecious spreading shrub to 1.5 m high. Leaves simple, obovate, or sometimes oblanceolate or oblong; to 3.5 cm long and 15 mm wide, glabrous. Flowers small yellow, usually 2 or 3 together, rarely in a few-flowered terminal cyme, Flowering between August and November. Fruits are yellow-red capsule, 3- rarely 4-angled to 8.5 mm long and 8.5 mm wide; glabrous, leathery. Seeds are dark brown to black ovoid seeds to 4 mm, with a noticable white aril. Seed embryo type is folded.
Seed collection and propagation
Collect seeds between November and January. Collect capsules that contain hard black seeds, usually when capsule is turning yellow-red. 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. This species has physiological dormancy that needs to be overcome for the seed to germinate (e.g. nicking the seed coat).
