Plant description

Green sticky dioecious shrubs with ascending branches to 150 cm high;, slender, with viscid angles and lines of white hairs. Leaves very variable, linear to lanceolate to 20 mm long and 7 mm wide; obtuse, truncate or rounded at the summit. Base attenuated into a distinct petiole to 2 mm long; margins more or less recurved, shiny and green above. Leaves have white hairs beneath except on the narrow conspicuous midrib; the lateral veins are obscure. Calyx has 5 overlapping glabrous sticky lobes, without petals; bracts triangular to 0.5 mm long, brown, leathery, sticky. Male flowers in groups of 1-3 in the leaf axils on slender more or less sticky peduncles. Light-green to yellow or white, reddened in parts, pubescent at the base and more or less glutinous. Flowering between September and November. Fruits are dark green ovoid or globular capsule to 7 mm long, containing 3 seed. Seeds are mottled brown oblong seed oblong to 5 mm long and 3 mm wide, topped by a yellow fleshy aril. Seed embryo type is spatulate.

Seed collection and propagation

Collect seeds between November and January. Collect maturing capsules, fat, green and containing dark, hard seed. Place the capsules in a tray and leave to dry for a week or two. Then gently rub the capsules with a rubber bung to dislodge the seeds. Use a sieves 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 can be variable and seeds are prone to predation. This species is generally difficult to germinate, it has morphophysiological dormancy and complex germination requirement.
