Name derivation:
Caladenia from the Greek 'kallos' 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. Behrii named after Hans Hermann Behr (1818-1904), a German-American doctor, entomologist and botanist, who collected in South Australia.
Distribution:
Endemic to South Australia and found only in the Mount Lofty Ranges, growing on the upper slopes and crests of moderate to steep hills in sandy loam soils in Eucalyptus woodlands.
Status:
Native. Very rare in South Australia. Endangered in Australia (EPBC Act).
Plant description:
Terrestrial orchid to 60 cm high in flower with a single hairy leaf to 10 cm long emerging in winter. Inflorescence on a hairy slender stem with one or two  creamy white flowers with a pinkish-red lip (labellum) that is curled under. Petals and sepals to 8 cm long with red glandular tips that produce a strong musky fragrance. Flowering between August and September.
Fruit type:
Brown hairy, papery ellipsoid capsule containing numerous tiny seeds.
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, refrigerator or in liquid nitrogen.
