Name derivation:
Caladenia from the Greek 'callos' meaning beauty and 'aden' meaning a gland; referring to the colourful labellum and the glistening glands at the base of the column that adorn many of the species. Cucullata meaning hood-shaped.
Distribution:
Found only in a small area in South Australia, between Bordertown and Naracoorte, growing in deep sand under Eucalyptus baxteri. Also found in New South Wales, Victoria and Tasmania.
Status:
Native. Rare in South Australia. Common in the other states.
Plant description:
A slender little herb to 10-25 cm high with up to 6 small flowers borne on wiry stems. The single basal leaf is linear, 10-25 cm long and sparsely hairy. Flowers are 10-35 mm in diameter. Tepals are 15 mm long with a white interior and green to brown exterior covered with glandular hairs, the white labellum has a red to purple mid-lobe. Flowering between September and November.
Fruit type:
Brown papery ellipsoid capsule.
Seed type:
Very small brown ellipsoid seed with a long cylindrical translucent brown mesh-like covering.
Seed collecting:
Collect fat capsules as they start to dry and turn brown. Pods will split and release the seeds quickly and will require monitoring. To increase the chances of collecting mature pods, it is recommended that a small breathable bag (ie. Organza bags) be used to enclose the developing capsules.
Seed cleaning:
Place the capsules in a container that will hold fine seeds and leave to dry for a few weeks or until the capsule split. Then carefully hold the capsule and tap it gently to release the seeds. 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 or in liquid nitrogen.
Seed viability:
For the NVC South East Orchid Project a total of six populations consisting of more than 1000 individuals in total were recorded in the Bangham, Geegeela & Binnum areas. A total of 6,200,000 seeds (0.91g) were banked for these six observed populations. Seed viability ranged from 50% to 75%.
