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 arabicaVerticillata from Latin 'verticillatus' meaning whorl, referring to the leaves arranged in whorls or seemingly so. Ovoidea from the Latin 'ovoideus' meaning egg-shaped, referring to the subspecies having flowers in globular or ovoid heads, rather than in spikes.
Distribution:
Found in the southern Flinders Ranges, Kangaroo Island, Mount Lofty Ranges and the South-east in South Australia, growing in damp places in heathland and woodland.  Also found in Victoria and Tasmania.
Status:
Native. Uncommon in South Australia. Common in the other states.
Plant description:
Spreading to prostrate shrub to 2 m high. Leaves alternate or fascicled, rarely whorled, often flattened, to 15 mm long and 1 mm wide, pungent tip. Flowers in ovoid or spherical heads to 1.2 cm long. Easily distinguished from other subspecies by its short, pungent, verticillate or fascicled phyllodes, and its densely packed globular or ovoid flower-heads. Flowering between August and November.
Fruit type:
Dark-brown, linear pod to 80 mm long and 4 mm wide; flat, straight or curved with pale margins, slightly thickened.
Seed type:
Hard, black oblong seed to 4 mm long and 1.5 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 germination:
This species has physical dormancy that needs to be overcome for the seed to germinate (e.g. nicking or softening the seed coat).
