Plant description

Dioecious erect shrub to 3 m high. Leaves either irregularly pinnatifid or irregularly 2–12-lobed, or rarely leaf entire; leaf blade linear to linear-oblanceolate, obtuse; to 5.5 cm long and 2.5 mm wide, glabrous to sparsely hairy; lobes 1–1.5 mm long, rarely to 5 mm; apex obtuse or rounded. Flowers 2 or 3 together, axillary; sepals 3 or 4, stamens 6-8. Flowering between May and July. Fruits are red-brown capsules 3- or rarely 4-winged, to 21 mm long and 15 mm wide; glabrous with wings extending from the base to the apex of the capsule. Seeds are black ovoid seed to 3 mm long and 2.5 mm wide with a short brown aril. Seed embryo type is folded.

Seed collection and propagation

Collect seeds between August and November. 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 high, at 80%. This species has physiological dormancy that needs to be overcome for the seed to germinate (e.g. nicking the seed coat).
