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. Glandulicarpa from the Latin 'glandula' meaning a small gland and Greek 'karpos' meaning fruit, referring to the legume covered with glandular  hairs.
Distribution:
Found in two small populations in South Australia, the main population in the northern Mount Lofty Ranges, in the Burra Gorge area on rocky hillside in open scrub vegetation and also in the South-east close to Victoria. Also found in Victoria.
Status:
Native. Very rare in South Australia. Very rare in Victoria.
Plant description:
Somewhat viscid, rather dense, rounded, spreading, much branched shrubs to 2 m high with a dull olive-green foliage. Branches grey-brown, terete, pubescent, marked with small raised leaf bases along the stems. Leaves obliquely oblong-obovate to more or less elliptical to 12 mm long and 6 mm wide, erect, thick, rigid, glabrous, minutely glandular, sometimes viscid when young; lower edges usually undulate, 2-veined with the central vein more prominent. Inflorescences simple and axillary, solitary or twin with globular, bright yellow flower-heads.  Flowering between July and October.
Fruit type:
Narrowly oblong, straight or curved pods to 3 cm long and 3 mm wide, viscid and covered with glandular shining hairs.
Seed type:
Hard, dark brown, obovoid to ellipsoid seeds to 5 mm long and 3 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 four collections, the seed viability was very low to high, ranging from 5% 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).
