Small herb with flowering stems to 20 cm high. Lowest leaves in a flat rosette, circular to reniform, to 6 mm diameter. Stem leaves alternate or in clusters, lamina with 2 acute lobes, to 6 mm diameter, peltate on slender petiole to 9 mm long, stipules absent. Inflorescence to 10 cm long with 2–8 white or pink flowers. Flowering between August and November.
Fruit type:

Seed collecting:
Collect mature capsules, those that are fat, hard, turning brown and contain black seeds inside.
Seed cleaning:
Place the capsules in a tray and leave to dry for one to 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.
