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. Dodonaeifolia from 'dodonaea' genus named after Dodonaeus, the Latinised name of Rembert Dodoens (1517-1588), a Belgian botanist and Latin 'folium' meaning leaf, having leaves like Dodonaea.
Distribution:
Endemic to South Australia and found mainly on southern Eyre Peninsula and southern  Mt Lofty Ranges, with minor occurrences on southern Yorke Peninsula, Kangaroo Island and the South-East.  Grows in woodland and open forest vegetation in hard acidic, yellow duplex, red shallow porous loamy, sandy alkaline yellow duplex soils.
Status:
Native. Rare in South Australia.
Plant description:
Tall, viscid shrubs or small trees to 6 m high, with short, thin trunks and long ascending branches,  sometimes covered with a blackish sooty substance. Leaves lanceolate or linear-lanceolate to 10 cm long and 10 mm wide; flat, punctate, quite viscid and sticky when young, becoming less viscid when mature and with a prominent central vein. Inflorescences axillary, mostly twin, sometimes on a very short common peduncle with globular, bright yellow flower-heads. Flowering between July and November.
Fruit type:
Light brown, linear, straight or curved pods to 10 cm long and 6 mm wide, raised over the seeds.
Seed type:
Hard, dark brown, oblong to ellipsoid seed to 6 mm and 3.5 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 high, at 100%.
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).
