Reinstatement of the Western Australian genus Oxymyrrhine (Myrtaceae: Chamelaucieae) with three new species
RYE, B.L.
The south-western Australian genus Oxymyrrhine Schauer is reinstated and the type species, previously known as Baeckea polyandra F. Muell., is restored to its earlier name of O. gracilis Schauer.A lectotype is selected for B. polyandra and three new species, Oxymyrrhine cordata Rye & Trudgen, O. coronata Rye & ; Trudgen and O. plicata Rye & Trudgen_,_ are described. These four species make up a group described here as Oxymyrrhine s. str. and are distinguished from other members of Oxymyrrhine s. lat. and from all other genera of tribe Chamelaucieae by the broad cavity in the summit of their fruit. Oxymyrrhine s. lat. includes a particularly difficult species complex, which will be revised at a later time.
