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. Dictyophleba from the Greek 'dictyon' meaning net or network and 'phlebs' meaning a vein, referring to the prominent net-veined phyllodes.
Found scattered in the northern part of South Australia from the far North-Western region, eastward to the Lake Eyre region in the Simpson Desert area in open woodland or hummock grassland in red siliceous sands. Also found in Western Australia, Northern Territory and Queensland.
Native. Common in South Australia. Common in the other States.

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 viability:
From one collection, the seed viability was high, at 85%.
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).
