Name derivation:
Diuris from the Greek 'dis' meaning double and 'oura' meaning a tail; referring to the pendulous lateral sepals resembling tails on some species. Behrii named after Hans Hermann Behr (1818-1904), a German-American doctor, entomologist and botanist, who collected in South Australia.
Distribution:
Found in the southern Flinders Ranges and the Mount Lofty Ranges with a few records from the Eyre Peninsula, growing in native grassland, open woodland and grassy forest on more fertile soils, especially amongst Kangaroo Grass and Triodia on gentle slopes and flats. Also found in New South Wales and Victoria.
Status:
Native. Very rare in South Australia. Rare in Victoria. Uncommon in New South Wales.
Plant description:
terrestrial orchid to 40 cm tall in flower. Leaves three to six, narrow-linear, grass-like, to 20 cm long. Inflorescence one to four, drooping, with bright yellow with an orange labellum flowers. Pedicel enclosed within bract. Dorsal sepal projected forward or obliquely erect, to 17 mm long. Lateral sepals obliquely defiexed, parallel, to 25 mm long, greenish. Petals spreading or drooping, to 25 mm long, claw green, lamina yellow. Labellum to 28 mm long, orange, often with brownish streaks. Flowering between September and October.
Fruit type:
Brown papery ellipsoid capsule.
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.
