SA Census:
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. Eremaea from the Greek 'eremites' meaning of the desert; referring to the arid habitat of the species.
Distribution:
Found across most of South Australia except on Kangaroo Island and the South-east, growing in a range of habitats. Found in all states.
Status:
Native. Common in South Australia. Uncommon in Tasmania. Common in all the other states.
Plant description:
Decumbent annual herb with erect flowering stems to 20 cm long. Leaves basal and on flowering stems, alternate, sessile, lanceolate to narrow-elliptic with basal leaves to 5.5 cm long and 0.8 cm wide. Inflorescence erect spike with a few white, pale-pink to purple flowers. Flowering between August and November.
Fruit type:
Red-brown ovoid capsules to 5 mm long, with 3 valves.
Seed type:
Dark red-brown reniform seed to 0.5 mm diameter, coppery lustre at maturity and a warty 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.
Seed viability:
From three collections, the seed viability were high, ranging from 85% and 100%.
