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. Vitoriae refers to where the type specimen was collected, from Victoria River or upper Barcoo in Queensland or to Queen Victoria, for whom the river was named..
Distribution:
Widespread across South Australia from near Adelaide to the Flinders Ranges, growing in tall and low woodland on rocky hillsides, ridges and flats then extending to the north iand north-west parts of South Australia, growing in low shrubland and hummock grassland. Also found in Western Australia, Northern Territory, Queensland, New South Wales and Victoria.
Status:
Native. Common in South Australia. Common in the other states.
Plant description:
Tall dense, thorny, much-branched shrubs to 5 m high, with smooth  yellowish-green to grey bark, slightly fissured at the base of the trunk.. Leaves flat glaucous to light green, variable lanceolate-oblong, linear to broad-linear, or more or less elliptical, straight or falcate to 5 cm long and 8 mm wide, . 1 prominent central vein and inconspicuous lateral veins; apex acute or obtuse with a short straight or recurved mucro. Glands small, near base. Inflorescences axillary solitary, or mostly twin or along elongated raceme axes, with globular pale creamy- yellow flower-heads. Differs from Acacia victoriae ssp. arida which has very hairy branchlets and leaves, whereas A. victoriae ssp. victoriae has hairless branchlets and leaves. Flowering between August and December
Fruit type:
Light brown, thin and papery, flattish, pod to 8 cm long and 13 mm wide; surfaces usually showing the outline of the seed with slightly thickened margins with some constrictions.
Seed type:
Hard, globular dark brown mottled seed to 6 mm long and 4 mm across.
Embryo type:
Investing.
Seed collecting:
Collect mature pods that are turning brown, with hard, dark seeds inside. Be careful when collecting pods, as plants can be long spined.
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).
