Census of South Australian plants (external link)     [genus Acacia]
Name derivation:
Acacia from the Greek 'akakia' and derived from 'ake' or 'akis' meaning a sharp point or thorn and 'akazo' meaning to sharpen. Dioscorides, the Greek physician and botanist, used the word in the 1st century AD for the Egyptian thorn tree, Acacia arabica. Aneura from the Greek 'a' meaning not, without and 'neuron' meaning a nerve, referring to the obscure veins on the phyllodes.
Distribution:
Found in the arid part of South Australia. Usually growing on shallow or gravelly soils on hills. Also found in Western Australia, Northern Territory, Queensland and New South Wales.
Status:
Native. Common in South Australia. Common in the other states.
Plant description:
Shrub or tree to 6m tall. Branchlets with white appressed and red-glandular hairs between resinous ribs. Leaves straight or curved, flat or rarely subterete to 9.5 cm long and 2.2 mm wide. Inflorescence axillary, solitary with cylindrical pale-yellow flower-heads.
Fruit type:
Brown, flat-oblong pod to 4 cm long and 10 mm wide, with resinous rim or rarely with wings to 0.4 mm wide, with some fine hairs.
Seed type:
Brown ovoid seeds to 5 mm long and 3 mm wide, with a long aril.
Embryo type:
Investing.
Seed collecting:
Collect mature pods that are turning brown with hard, dark seeds inside.
Seed cleaning:
Place the pods in a tray and leave to dry for 1-2 weeks or until the pods begin to split. Then rub the dried pods to dislodge the seeds. Use a sieve to separate any unwanted material. 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:
This species has physical dormancy that needs to be overcome for the seed to germinate (e.g. nicking or softening the seed coat).
