Sources that [synonymized](/source/Synonym_(taxonomy)) ''Coelorachis'' with ''Mnesithea'' accepted about 26 species. Those that synonymized ''Coelorachis'' with ''[Rottboellia](/source/Rottboellia)'' accepted about seven. ==Taxonomy== The genus ''Mnesithea'' was erected by [Carl Sigismund Kunth](/source/Carl_Sigismund_Kunth) in 1829. The [circumscription](/source/Circumscription_(taxonomy)) of the genus varied {{As of|2024|November|lc=yes}}. A 2015 classification of Poaceae treated ''Coelorachis'' as a synonym of ''Mnesithea''. This treatment was supported by Welker et al. in 2020, based on a [molecular phylogenetic](/source/Molecular_phylogenetics) study, and was used by the [Germplasm Resources Information Network](/source/Germplasm_Resources_Information_Network) and the [Integrated Taxonomic Information System](/source/Integrated_Taxonomic_Information_System). In this circumscription, the genus has about 26 species including those formerly placed in ''Coelorachis''. Alternatively, [Plants of the World Online](/source/Plants_of_the_World_Online), following Veldkamp et al. in 2013, treated ''Coelorachis'' as a synonym of ''[Rottboellia](/source/Rottboellia)'', with only seven species in the genus ''Mnesithea''. ===Species=== Seven species were accepted in the narrow circumscription {{As of|2024|November|lc=yes}}: * ''[Mnesithea annua](/source/Mnesithea_annua)'' (Lazarides) de Koning & Sosef - [Western Australia](/source/Western_Australia) * ''[Mnesithea formosa](/source/Mnesithea_formosa)'' (R.Br.) de Koning & Sosef - [Lesser Sunda Islands](/source/Lesser_Sunda_Islands), [New Guinea](/source/New_Guinea), [Western Australia](/source/Western_Australia), [Northern Territory](/source/Northern_Territory), [Queensland](/source/Queensland) * ''[Mnesithea laevis](/source/Mnesithea_laevis)'' (Retz.)
