A revision of the Micromyrtus racemosa complex (Myrtaceae: Chamelaucieae) of south-western Australia
RYE, B.L.

The Micromyrtus racemosa species complex, which is endemic to south-western Australia, is revised. The complex includes two previously named species, M. racemosa Benth. and M. trudgenii Rye. Six new taxa are described here: M. arenicola Rye, M. collina, M. greeniana, M. mucronulata, M. prochytes and M. rubricalyx. Descriptions are also given for two new taxa that are considered to be too poorly known at present to name. Also included are distribution maps and a key to all members of this complex, and an illustration of M. mucronulata by Charles Gardner.
