Status:
Native. Uncommon in South Australia.
Plant description:
Greyish to green sparsely branching annual herb to 20 cm high, covered with densely nipplelike projection. Leaves ovate to oblanceolate, somewhat fleshy, to 30 mm long and 11 mm wide. Flowers solitary, terminal or in the forks of the branches, purple or pink inside. Flowering between September and October.

Seed collecting:
Pick mature capsules when they turn a straw colour and contain hard dark seeds.
Seed cleaning:
Place the capsules in a tray and leave to dry for at least a week. Then rub the dried capsules 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 95%.
