Plant description

Shrub or a tree to 10 m tall with long green alternate leaves, drooping on the branches. Flowers unisexual (possibly sometimes bisexual), sweet-scented; males mostly in axillary clusters of up to 6; females usually solitary in axils; yellow-cream with curved petals. Flowering between August and November. Fruits are orange ovoid capsules that split into two and contain numerous seeds. Seeds are red sticky seeds to 6 mm long and 4 mm wide. Seed embryo type is linear underdeveloped.

Seed collection and propagation

Collect seeds between September and February. Collect by hand fruits that are orange in colour, opened or unopened. Place the fruit in a tray and leave to dry for at least two weeks. The fruit will split and open as it dries. Once the fruits split, use your fingers or a small spoon to extract the seeds. 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 100%.
