Native. Common in South Australia. Rare in Tasmania. Common in Victoria.
Plant description:
Small wiry shrub with erect or decumbent branches generally less than 50 cm high, with young parts hairy. Leaves alternate, linear to terete, to 6 mm long and 0.7 mm wide, channelled above, outer surface silky or glabrous with age, stipules triangular.Inflorescence singly at tips of short lateral branchlets with yellow to red pea-flowers. Flowering between September and November.
Fruit type:
Hairy dark brown ovoid pod, almost hidden within calyx and bracts.
Embryo type:
Bent.
Seed collecting:
Collect maturing pods, those that are brown or turning brown and contain hard seeds inside. 
Seed cleaning:
Place the pods in a paper bag and leave to dry for one to two weeks. Then rub the pods with a rubber bung to dislodge the seeds. Use a sieve to separate the 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. The seed coat needs to be ruptured so that water can enter the seed before germination can occur. Methods to rupture the seed coat include scarification with sand paper or nicking the seed coat with a sharp blade or hot water treatment by immersion in boiling water.
