Name derivation:

Found in the South-east in South Australia, growing in the understorey of open forest, ephemeral after fire or other disturbance. Also found in New South Wales, Victoria and Tasmania.
Status:
Native. Rare in South Australia. Rare in New South Wales. Common in the other states.
Plant description:
Annual or perennial herbs with a tap root, and one to few stiffly erect stems up to 35 cm long, glabrous. Leaves sessile, linear-oblanceolate with a cuneate base and often distant marginal teeth at the base of the plant but often already dried up by the time the flowers are open becoming linear-lanceolate to awn-shaped on the stems, 1to 3.5 mm long 4 mm wide, glabrous. Flowers along a long spike with blue flowers with lobes triangular, the tube off-white becoming blue like the lobes and split along the upper side, the upper 2 lobes short, the lower 2 lateral lobes longer but about half the length of the oblanceolate median lobe. Flowering between November and January.
Fruit type:
Brown obovoid capsule to 8 mm long.
Seed type:
Brown triangular seed to 0.7 mm long and 0.3 mm wide, smooth.
Embryo type:
Linear under-developed.
Seed collecting:
Collect mature capsules, those that are fat, turning a pale straw colour and contain brown seeds.
Seed cleaning:
Place the capsules in a tray and leave to dry for one weeks. Then rub the capsules gently by hand to dislodge the seeds. Use a sieve to separate the unwanted material. Be careful as the seeds are very small. 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.
