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. Colletioides from the genus Colletia (genus named for Philibert Collet, 17th century French botanist) and Greek 'oides' meaning resemblance to, referring to its resemblance to Colletia.
Distribution:
Found across the Central part of South Australia from the North-Western to the  Murray regions, associated with open scrub or low woodland. Also found in Western Australia, Northern Territory, New South Wales and Victoria.
Status:
Native. Common in South Australia. Common in the other states.
Plant description:
Dense, much-branched, rigid, prickly, rounded, spreading shrubs to 4 m high, often spreading more than its height.  Terete branches with grey to reddish-brown bark, slightly fissured at the base of stems. Leaves to 4 cm long and 1.5 mm diameter, terete, or almost so, very rigid, pungent, spreading to sometimes almost horizontal with approximately 8 prominent longitudinal veins. Small glands 1-2 mm above the base. Inflorescences axillary and solitary, usually twin or sometimes in clusters up to 5 small, more or less globular, yellow flower-heads. Flowering between August and October.
Fruit type:
Dark brown narrow-oblong, curved or twisted pods to 5 cm long and 5 mm wide. Margins slightly constricted between seeds.
Seed type:
Hard black ovoid-ellipsoid seeds to 4.5 mm long and 2.5 mm wide.
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 viability:
From one collection, the seed viability was average, at 60%.
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).
