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. Calamifolia from the Latin 'calamus' meaning a reed and 'folium' meaning leaf, referring to the species' reed-like leaves.
Found in the southern part of South Australia in the Eyre Peninsula, Yorke Peninsula, Flinders Ranges, Northern and Southern Lofty, Kangaroo Island, South-Eastern, Murray and Eastern regions, mainly associated with woodland and open scrub. Also found in New South Wales and Victoria.
Native. Common in South Australia. Common in the other States.
Plant description:
Tall, erect, glabrous, rounded, bushy shrubs to 4 m high. Branchlets slender, ascending, reddish with smooth bark, grey on older stems. Leaves linear to 12 cm long and 5 mm wide, mainly terete-compressed but sometimes flat, straight or slightly curved, with 1 obscurely vein on each face. Small glands situated on upper margin 5-10 mm from the base of the leaves. Inflorescences axillary, solitary or 2-4 globular, yellow flower-heads. Flowering between August and November.
Fruit type:
Brown linear, straight or curved pods to 15 cm long and 6 mm wide, raised and wrinkled over the seeds. Margins straight-edged or slightly constricted.
Seed type:
Hard black obvoid seeds to  6 mm long and 2.5 mm wide.
Embryo type:
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 95%.
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).
