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. Ptychrosperma from the Greek 'ptyche' meaning a fold and 'sperma' meaning seed; referring to the concentric ribs around the seeds.
Distribution:
Found across the northern part of South Australia, growing in sandy watercourses or low-lying areas, but also in rocky loams and clay pans. Found in Western Australia, Northern Territory, Queensland and New South Wales.
Status:
Native. Common in South Australia. Common in the other states.
Plant description:
Prostrate to decumbent annual herb with stems to 40 cm long. Leaves basal and on flowering stems, alternate, sessile, linear to lanceolate, often terete, to 70 mm long and 3 mm wide. Inflorescence loose spike (erect to spreading in fruit) with pink to purple flowers. Flowering between August and October.
Fruit type:
Red-brown ovoid to conical capsules to 7 mm long with 4 valves.
Seed type:
Dark red-brown reniform-ovoid seed to 0.6 mm long and 0.5 mm wide, with concentric ribs.
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 one collection, the seed viability was high, at 100%.
