Synopsis of the tribe Chloantheae and new nomenclatural combinations in Pityrodia s.lat. (Lamiaceae)

An overview of the tribe Chloantheae (Lamiaceae) is presented. Nomenclatural changes associated with reinstating Dasymalla Endl. and Quoya Gaudich. as distinct genera from Pityrodia s.lat. are provided. The genus Dasymalla consists of five species previously in Pityrodia, whereas seven species of the latter genus are transferred to Quoya. The circumscription of Hemiphora F. Muell. is expanded to include four species previously included in Pityrodia and Hemiphora lanata (Munir) B.J. Conn & M.J. Henwood is formally recognised as a species, based on Pityrodia exserta (Benth.) Munir var. lanata Munir. The new genus Muniria N. Streiber & B.J. Conn is described and consists of four species occurring in the Northern Territory (Australia) that were previously in Pityrodia. A summary of the diagnostic features of Dasymalla, Hemiphora, Muniria and Quoya is presented. The synapomorphies supporting the genera of 'Physopsideae' sensu Munir are described, whereas no synapomorphies for Newcastelia or Physopsis were found in the data. Akey distinguishing the genera of the tribe is included.
