Eucalyptus revelata, a rare new species related to E. mooreana (Myrtaceae) from the Kimberley region of Western Australia

Two variants of E. mooreana W.Fitzg. s. lat., a rare species from the Kimberley region of Western Australia, are found to be specifically distinct. A revised description of E. mooreana is provided and E. revelata D.Nicolle & R.L.Barrett is described to accommodate plants with a more sprawling habit, less powdery and less uniformly-coloured bark, non- or weakly-pruinose features, green leaves and generally smaller fruits. Both E. mooreana and E. revelata are restricted to steep rocky slopes and mountain ridges in the higher parts of the King Leopold Ranges. A key to the terminal taxa of Eucalyptus ser. Subexsertae (Benth.) Blakely (the ‘northern white gums’) is provided. Authorship of the name E. mooreana is discussed and attributed to W.V. Fitzgerald rather than J.H. Maiden. A new lectotype is designated as the previous designation was found to be ineffective.
