Endemic to South Australia and found in the central part of the state, growing among rock outcrops .
Status:
Native. Common in South Australia.
Plant description:
Robust decumbent herb to 20 cm tall. Leaves 3 to 10 cm long and 24 mm wide, broad, leathery and easily recognisable even when not in flower. Inflorescence spike with 1-5 large bright pink flowers. Flowering between May and August.
Fruit type:
Pale brown box-like capsule to 25 mm long. Largest of any Australian Wurmbea.
Seed type:
Orange brown globular seed to 2 mm diameter.
Embryo type:
Linear under-developed.
Seed collecting:
Collect mature capsules, those turning pale straw colour and containing hard brown seeds. 
Seed cleaning:
Place the capsules in a tray and leave to dry for two weeks. Then rub the capsules gently by hand 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 viability:
From one collection, the seed viability was high, at 100%.
