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. Vittata from the Latin 'vittatus' meaning longitudinally-striped; referring to the markings on the fruit.
Distribution:
Endemic to South Australia and found on the Eyre Peninsula, Kangaroo Island, Fleurieu Peninsula and the South-east, growing on sand, usually in limestone areas in mallee scrub
Status:
Native. Common in South Australia.
Plant description:
Prostrate, straggly or dense shrub to 2 m tall with hairy young branches. Leaves terete, to 80 mm long and 1.5 mm wide, glabrescent, pungent tip. Inflorescence axillary clusters with 1–8 reddish outside,white inside flowers. Flowering between August and November.
Fruit type:
Greyish-brown woody ovoid fruit to 24 mm long and 15 mm wide, with smooth or wrinkled surface and two short beaks. Fruit split into two to reveal two seeds.
Seed type:
Dark brown to black ovoid seed to 7 mm long and 4 mm wide (15 mm long and 7 mm wide including the wing that extend down both sides of seed).
Embryo type:
Investing.
Seed collecting:
Collect mature woody fruit that are greyish-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. Fruits can be placed in the oven at low temperatures to achieve the same result. 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 viability:
From one collection, the seed viability was high, at 85%.
Seed germination:
Seeds are non-dormant, viable seed should germinate readily without pre-treatment.
