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 flower 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 and 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 tuberculate 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.
