Name derivation:
Chamaescilla from the Greek 'chamai' meaning dwarf and 'skilla' meaning a squill or sea onion, a liliaceous plant of the Mediterranean region. Corymbosa from the Latin 'corymbosus' meaning a cluster of flowers.
Distribution:
Found in the southern part of South Australia, from the southern Flinders Ranges to the lower South-east, growing in seasonally moist soils. Also found in Western Australia, Victoria and Tasmania.
Status:
Native. Common in South Australia. Common in the other states.
Plant description:
Small annual herb with leaves basal, grass-like, channelled with tuberous roots. Stem erect to15 cm high, bearing near the summit a loose corymb of 2 to many bright-blue flowers, spirally twisting after flowering. Flowering between August and October.
Fruit type:
Brown capsules with 3 laterally compressed lobes, acute on the dorsal edges, truncate at the summit.
Seed type:
Glossy black, semi-flat seed to to 1.5 mm diameter.
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 low, at 20%.
