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. Sclerophylla from the Greek 'scleros' meaning hard and 'phyllon' meaning a leaf; referring to the species' hard textured phyllodes.
Distribution:
Found from Streaky Bay on the west coast of Eyre Peninsula to Yorke Peninsula, Mount Lofty Ranges, and Murray region, growing on sandy alkaline yellow duplex, red shallow porous loam, brown calcareous earths and dark grey-brown calcareous loam earths.  Also found in Western Australia, New South Wales and Victoria.
Status:
Native. Common in South Australia. Common in the other states.
Plant description:
Low, much-branched,with grey bark shrubs spreading  to 2 m high, often much wider than high. Leaves thick, straight or slightly curved, narrowly oblanceolate to narrowly oblong-cuneate to 4 cm long and 4 mm wide. Inflorescences simple and axillary, solitary or twin with globular, bright yellow flower-heads. Flowering between July and October.
Fruit type:
Long, curved pod to 6cm long and 3 mm wide; finely twisted, raised over the seeds, with margins slightly constricted between seeds.
Seed type:
Dark brown to black, oblong to elliptic seed to 4 mm long and 2 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 two collections, the seed viability was average to high, ranging from 70% to 90%.
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).
