Russell L Barrett, Terry D Macfarlane, Gregory J Keighery

Abstract


The genus Corynotheca F.Muell. ex Benth. is revised and Corynotheca borealis R.L.Barrett, Keighery & T.Macfarlane is described as a new species from the east Kimberley region of Western Australia and the adjacent Northern Territory. Corynotheca dichotoma (F.Muell.) F.Muell. ex Benth. is reinstated for a species growing on yellow sands in the Mid west of Western Australia. The taxonomic and geographic limits of varieties of C. micrantha (Lindl.) Druce are reconsidered and all are recognised at specific rank. Four new combinations are made: Corynotheca divaricata (R.J.F.Hend.) R.L.Barrett & T.Macfarlane, Corynotheca elongata (R.J.F.Hend.) R.L.Barrett & T.Macfarlane, Corynotheca gracilis (R.J.F.Hend.) R.L.Barrett & T.Macfarlane and Corynotheca panda (R.J.F.Hend.) R.L.Barrett & T.Macfarlane. All are illustrated and a revised key to the thirteen species of Corynotheca recognised is provided.
