Census of South Australian plants (external link)     [genus Calandrinia]
Name derivation:
Calandrinia named after Jean-Louis Calandrini (1703-1758), a Swiss scientist, professor of mathematics and philosophy. Volubilis from Latin meaning to turn, revolve or twine; alluding to the species twining habit.
Distribution:
Found in the eastern central part of South Australia, growing in Atriplex vesicaria shrublands. Also found in New South Wales and Victoria.
Status:
Native. Rare in South Australia. Uncommon in the other states.
Plant description:
Spreading to erect annual herb with thickened tap root and twining flowering stems to 30 cm long. Leaves mostly basal with very few on lower parts of flowering stems, sessile, lanceolate to oblanceolate, to 5.5 cm long and 1 cm wide, fat and fleshy. Inflorescence loose panicles on long twining stem with pale pink flowers. Flowering between September and October.
Fruit type:
Red-brown narrow-ovoid capsule to 7.5 mm long with 3-valves, about twice as long as the sepals.
Seed type:
Dark red-brown reniform-ovoid seed to 0.7 mm long and 0.6 mm wide, with distinctive tuberculated surface.
Embryo type:
Peripheral.
Seed collecting:
Collect mature capsules, those that are turning a red-brown colour and contain dark seeds.
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.
