Small shrub or tree to 8 m high with hairy branchlets. Leaves terete, not grooved; to 100 mm long and 2 mm wide; white hairs, pungent tips. Inflorescence clusters with 18ï¿½45 white to yellow flowers. The two subspecies differ from each other only in the nature of the hairs of the inflorescence stalk (rachis), those of H. leucoptera ssp. leucoptera being white woolly-pubescent (raised), while those of H. leucoptera ssp. sericepes are shining white or brown and appressed (not raised). Flowering between October and December. Fruits are brown woody ovoid fruit to 32 mm long and 20 mm wide, with a broad pointed tip. Fruit splits into two to reveal two seeds. Seed embryo type is investing.
Seed collection and propagation
Collect seeds between January and March. Collect mature woody fruit that are hard, brown and not split. These will contain seeds. Place the woody fruit in a tray and leave to dry until it split open. Place the dried fruit in a bucket and shake to dislodge the seeds from the valves. Separate the seeds from the fruit and 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. Seeds are non-dormant, viable seed should germinate readily without pre-treatment.
