Census of South Australian plants (external link)     [genus Hakea]
Name derivation:
Hakea named after Baron Christian Ludwig von Hake (1745-1818), a German horticulturalist and patron of botany. Leucoptera from the Greek 'leucos' meaning white and 'ptero' meaning wing, referring to the pale wing on the seed of this species.
Distribution:
Found in central and northern South Australia, growing in a wide range of shrublands and woodlands on sandy to clay soil. Also found in all mainland States except Western Australia.
Status:
Native. Common in South Australia. Common in the other States.
Plant description:
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 18–45 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.
Fruit type:
Brown woody ovoid fruit to 32 mm long and 20 mm wide, with a fat pointed end. Fruit splits into two to reveal two seeds.
Embryo type:
Investing.
Seed collecting:
Collect mature woody fruit that are hard, brown and not split. These will contain seeds.
Seed cleaning:
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.
Seed germination:
Seeds are non-dormant, viable seed should germinate readily without pre-treatment.
