Plant description

Shrub 1-4 m high; branches sometimes viscid towards tips; leaves alternate, with thick entire margins, apex hooked. Flowers cream, 1-4 per axil, petals glabrous outside, ovary and style glabrous. Fruits are fleshy drupe, yellow to orange brown. Seeds are woody endocarb with vertical ribs and usually 2-4 locules. Seed embryo type is linear

Seed collection and propagation

Collect seeds between December and February. Collect ripe drupes when fleshy and fully coloured. Rub flesh off fruits using warm water and mild detergent over a sieve, or spread out to dry with flesh attached. Variable ranging from 40% to 80% from 2 collections

This species has physiological dormancy and is difficult to germinate. However, high levels of germination were observed after the woody endocarp was gently cracked with a vice and intact seeds were exposed or removed.

Germination research for this species was supported by AMLR NRM in 2017.
