Brachyelytrum is a genus of North American and East Asian plants in the grass family, classified in its own tribe Brachyelytreae.
Brachypodium is a genus of plants in the grass family, widespread across much of Africa, Eurasia, and Latin America. The genus is classified in its own tribe Brachypodieae.
Ampelodesmos is a genus of Mediterranean plants in the grass family, which is known by the common names stramma, Mauritania grass, rope grass, and dis(s) grass. It is classified in its own tribe Ampelodesmeae within the grass subfamily Pooideae.
Puelia is a genus of African grasses, the only genus in the tribe Atractocarpeae. It belongs to the subfamily Puelioideae, one of the early-diverging lineages in the grasses, but used to be considered a bamboo genus.
Littledalea is a genus of Asian plants in the grass family, native to mountains in China and neighboring countries. The genus is placed in its own tribe Littledaleae within subfamily Pooideae. The isolated tribe seems to be sister to the tribes Bromeae and Triticeae.
Streptogyna is a widespread genus of tropical plants in the grass family. It is the only genus in the monotypic tribe Streptogyneae.
Guaduella is a genus of African plants in the grass family, the only genus in the tribe Guaduelleae. It belongs to the subfamily Puelioideae, one of the early-diverging lineages in the grasses, but used to be included in the bamboos.

Lecomtella is a genus of grasses with the sole species Lecomtella madagascariensis, native to Madagascar. It is the only genus in the tribe Lecomtelleae.
Micraira is the only genus of tribe Micraireae in the grass family, native to Australia.
Relchela is a genus of plants in the grass family. The only known species is Relchela panicoides, native to Chile and Argentina.
The Stipeae are a tribe of grasses within the subfamily Pooidae, with up to 600 described species.
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.
Oryzoideae (syn. Ehrhartoideae) is a subfamily of the true grass family Poaceae. It has around 120 species in 19 genera, notably including the major cereal crop rice. Within the grasses, this subfamily is one of three belonging to the species-rich BOP clade, which all use C3 photosynthesis; it is the basal lineage of the clade.
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.
Micrairoideae is a subfamily of the grass family Poaceae, distributed in tropical and subtropical regions. Within the PACMAD clade, it is sister to subfamily Arundinoideae.
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.
Lorezochloa is a genus of flowering plants in the grass family, Poaceae. It includes eight species native to the tropical Americas, ranging from northeastern Mexico to northwestern Venezuela and northwestern Argentina.
