Coleataenia is a genus of grasses in the tribe Paniceae of the family Poaceae. Until recently this genus was part of Panicum. In 2010, Zuloaga, Scataglini, & Morrone proposed the transfer of the Panicum sections Agrostoidea and Tenera to the new genus, Sorengia. However, that same year, because one of the new species' synonyms was in the valid genus Coleataenia, Robert J. Soreng determined that Sorengia was not a valid name for the new genus and re-published it as Coleataenia.
Danthonioideae is a mainly southern hemisphere subfamily of grasses, containing the single tribe Danthonieae and one unplaced genus, with altogether roughly 300 species. It includes herbaceous to partially woody perennial or annual (less common) grasses that grow in open grasslands, shrublands, and woodlands. It belongs to the PACMAD clade of grasses, but unlike some other lineages in that clade, grasses in the Danthonioideae exclusively use the C3 photosynthetic pathway. Its sister group is the subfamily Chloridoideae.
Paniceae is a large tribe of the subfamily Panicoideae in the grasses (Poaceae), the only in the monotypic supertribe Panicodae. It includes roughly 1,500 species in 84 genera, primarily found in tropical and subtropical regions of the world. Paniceae includes species using either of the C4 and C3 photosynthetic pathways, as well as presumably intermediate species. Most of the millets are members of tribe Paniceae.
Stapfochloa is a genus of grasses. It is also in the subfamily Chloridoideae, and the Cynodonteae tribe.
Brylkinieae is a tribe of grasses, containing a single genus, Brylkinia. It used to be placed in tribe Meliceae, and had previously included a second genus, Koordersiochloa.
Paspaleae is a tribe of the Panicoideae subfamily in the grasses (Poaceae), native mainly to the tropical and subtropical Americas but with a number of species introduced to other regions. It includes roughly 680 species in 39 genera. Species in this tribe use either of the C3 or C4 photosynthetic pathways.
