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. Parviflora from the Latin 'parvus' meaning small and 'floris' meaning flower. Vittata meaning striped; referring to the transverse veins on the petals.
Distribution:
Found in a very small area in the lower South-east in South Australia, in damp open grassy areas in swamp and forest. Also found in Queensland, New South Wales, Victoria and Tasmania.

Native. Very rare in South Australia. Uncommon in Victoria and Tasmania. Common in the other states.

Fruit type:
Pale brown 3-lobed capsules.
Seed type:
Globular black seed to 2 mm diameter with a tuberculate surface, some much longer.

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.

From two collections, the seed viability were average to high, ranging from 40% to 80%.
