Census of South Australian plants (external link)     [genus Caesia]
Name derivation:
Caesia named after Federico Cesi (1585-1630), an Italian naturalis who is said to have been the first to discover the spores of ferns and whose name was Latinised as Caesius. Calliantha from the Greek 'callos' meaning beauty and 'anthos' meaning flower.
Distribution:
Found in the southern part of South Australia from the southern Flinders Ranges to the lower South-east, growing in grassy understorey of sclerophyll forest on damp sandy or clay soil. Also found in New South Wales, Victoria and Tasmania.
Status:
Native. Common in South Australia. Common in the other states.
Plant description:
Tufted, glabrous herbaceous perennial lily with long grass-like leaves to 50 cm long and 15 mm wide, sheath, often papery. Flowers lilac-blue to deep-blue along a long spike. Flowering between August and October.
Fruit type:
Pale brown capsule to 8 mm in diameter with 3-lobed.
Seed type:
Globular black seeds 2 mm in diameter, with fine irregular low tubercles.
Embryo type:
Linear fully developed.
Seed collecting:
Collect mature capsules, those that are turning a pale straw colour and contain black seeds. Can collect individual capsules or break off the whole spike.
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 average, at 65%.
Seed germination:
High germination rates after 4 weeks cold stratification at 5C and sown April (pers. comm. Shaun Kennedy - SA Water) - see seedling images on Sosa webpage.
