Abstract

Orchidaceae occuring in the Kimberley region of Western Australia are revised. Calochilus barbarossa R.L.Barrett, M.D.Barrett & K.W.Dixon, Calochilus kimberleyensis R.L.Barrett, M.D.Barrett & M.A.Clem., Dipodium ammolithum M.D.Barrett, R.L.Barrett & K.W.Dixon and Dipodium basalticum M.D.Barrett, R.L.Barrett & K.W.Dixon are described and illustrated as new species from the Kimberley, one also occurring in the Northern Territory. The genera Empusa Lindl., Habenaria Willd. s. str., Phoringopsis D.L.Jones & M.A.Clem., Spiranthes Rich. and Zeuxine L. have been added to the Western Australian flora since publication of the Flora of the Kimberley Region. The taxonomic status of a number of tropical Australian Orchidaceae is discussed with recommendations for future research. Descriptions and illustrations are provided for twenty orchid species recorded in the Kimberley Region (one without a verified voucher). Keys are presented to all Kimberley orchid species.
