Description
Orchids in the genus Eriochilus are terrestrial,
sympodial herbs usually with a few inconspicuous, fine roots and a roughly spherical, succulent tuber. Replacement tubers form at the end of short "droppers". There is a single, glabrous, egg-shaped to lance-shaped leaf either at the base, or in the middle of the flowering stem.[2][3][4][5][6][7]
The
Taxonomy and naming
The genus Eriochilus was first formally described in 1810 by
Prodromus Florae Novae Hollandiae.[8][9] The botanical name Eriochilus is derived from the Ancient Greek words ἔριον erion meaning "wool"[10]: 864 and χεῖλος cheilos meaning lip[10]: 486 referring to the hairy labellum.[2]
Distribution and habitat
Ten species of bunny orchids occur in Western Australia where they are found in a range of habitats from areas that are swampy in winter to dry inland
Israelite Bay on the south coast.[2] Three species are found in the south-east of South Australia, including the Eyre Peninsula and Yorke Peninsula.[6][11] Two species are found in Victoria,[7] three in New South Wales. Bunny orchids are also found in Queensland and Tasmania.[5]
