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. Calyptrata from the Latin 'calyptratus’ meaning bearing a cap-like covering; possibly referring to the persistent sepals around the capsules.
Distribution:
Found in the southern part of South Australia except the lower South-east, growing in sandy and gravelly soils, often associated with granite. Also found in Western Australia, New South Wales, Victoria and Tasmania.
Status:
Native. Common in South Australia. Common in the other states.
Plant description:
Prostrate, often reddish herb with stems to 20 cm long. Leaves basal and on lower part of flowering stems, alternate, sessile, oblanceolate to oblong to 3.5 cm long and 7 mm wide. Inflorescence open spike with pale pink flowers, sepals broad-ovate, persistent, petals 5, obovate to elliptic. Flowering between August to October.
Fruit type:
Reddish-brown ovoid capsule to 3.6 mm long, just exceeding the sepals, with 3 valves splitting at the apex and releasing numerous seeds.
Seed type:
Shiny reddish-brown reniform seed to 0.8 mm long and 0.7 mm wide, with a mesh-like surface.
Embryo type:
Peripheral.
Seed collecting:
Collect mature capsules, those that are turning a red-brown colour and contain brown 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 one collection, the seed viability was high, at 90%.
