Native. Common in South Australia. Uncommon in Tasmania. Common in Victoria.
Plant description:
Perennial herb with an erect rhizome arising from a globular tuber with stems to 60 cm long, simple, slender, leafy, trailing, scrambling or climbing. Lower leaves few, reduced and scale-like, alternate, upper leaves paired or in false whorls of 3 or 4, lamina orbicular-peltate, to 7 mm in diameter, deeply concave, inverted. Inflorescence a terminal raceme or panicle with 2 to several-flowers. Sepals 5, blackish, to 8 mm long, broad-elliptical or ovate, pilose, the hairs appressed, septate, glandular, margins ciliate below. Petals 5, white or pale pink, to 10 mm long, obovate. Flowering between July and October.
Fruit type:
Brown globose capsule to 8 mm diameter, nodding, enclosed in persistent sepals.
Seed type:
Black dumbbell-shape seed to 3 mm long and 0.5 mm wide.
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.
Seed viability:
From one collection, the seed viability was high, at 100%.
