Pooideae
The Pooideae are the largest subfamily of the grass family Poaceae, with about 4,000 species in 15 tribes and roughly 200 genera. They include some major cereals such as wheat, barley, oat, rye and many lawn and pasture grasses. They are often referred to as cool-season grasses, because they are distributed in temperate climates. All of them use the C3 photosynthetic pathway. The Pooideae are the sister group of the bamboos within the BOP clade, and are themselves subdivided into 15 tribes.

Poaceae
Poaceae () or Gramineae () is a large and nearly ubiquitous family of monocotyledonous flowering plants commonly known as grasses. It includes the cereal grasses, bamboos and the grasses of natural grassland and species cultivated in lawns and pasture. The latter are commonly referred to collectively as grass. With around 780 genera and around 12,000 species, the Poaceae is the fifth-largest plant family, following the Asteraceae, Orchidaceae, Fabaceae and Rubiaceae. The Poaceae are the most economically important plant family, providing staple foods from domesticated cereal crops such as maize, wheat, rice, barley, and millet as well as feed for meat-producing animals. They provide, through direct human consumption, just over one-half (51%) of all dietary energy; rice provides 20%, wheat supplies 20%, maize (corn) 5.5%, and other grains 6%. Some members of the Poaceae are used as building materials (bamboo, thatch, and straw); others can provide a source of biofuel, ...

BOP Clade
The BOP clade (sometimes ''BEP clade'') is one of two major lineages (or clades) of undefined taxonomic rank in the grasses (Poaceae), containing more than 5,400 species, about half of all grasses. Its sister group is the PACMAD clade; contrary to many species of that group who have evolved C4 photosynthesis, the BOP grasses all use the C3 photosynthetic pathway. The clade contains three subfamilies from whose initials its name derives: the bamboos (Bambusoideae); Oryzoideae (syn. Ehrhartoideae), including rice; and Pooideae, mainly distributed in temperate regions, with the largest diversity and important cereal crops such as wheat and barley. Oryzoideae is the earliest-diverging lineage, sister A sister is a woman or a girl who shares one or more parents with another individual; a female sibling. The male counterpart is a brother. Although the term typically refers to a family, familial relationship, it is sometimes used endearingly to r ... to the bamboos and Pooideae: ...

Hooker's Icones Plantarum 25: plate 2472 line drawing of ''Littledalea tibetica''; following page has description in Latin plus commentary in English The genus is placed in its own tribe Littledaleae within subfamily .

Ampelodesmeae
''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. The genus probably originated through ancient hybrid speciation, as a cross between parents from tribes Stipeae and Phaenospermateae. ''Ampelodesmos mauritanicus'' is a large clumping perennial bunchgrass, which is native to the Mediterranean region. It has been introduced outside its native range and is cultivated as an ornamental grass. Its nodding flower panicles can be nearly two feet long. In its native area it is used as a fiber for making mats, brooms, and twine. The plant can become an Invasive species in non-native ecosystems beyond the Mediterranean Basin. Its nodding flower panicles can be nearly two feet long. In its native area it is used as a fiber for making mats, brooms, and twine. The leaves of this grass are rea ...

Meliceae
The Meliceae are a tribe of grasses near the base of the Pooideae. They include two relatively large genera, ''Melica'' (based on accounts in multiple regional floras) with about 80-90 species and ''Glyceria'' with about 55 species.Tsvelev, N.N. 2006. Synopsis of the mannagrass genus, ''Glyceria'' (Poaceae). Bot. Zhurn. (Moscow and Leningrad). 2006. 91(2):255–276 Its other genera are ''Koordersiochloa'', ''Lycochloa'', ''Pleuropogon'', ''Schizachne'', and ''Triniochloa''. Distinguishing characteristics Members of the Meliceae have closed leaf sheaths; lemma veins that do not or only scarcely converge distally; and short, truncate, lodicules. They differ from Bromeae ''Bromus'' is a large genus of grasses, classified in its own tribe Bromeae. They are commonly known as bromes, brome grasses, cheat grasses or chess grasses. Estimates in the scientific literature of the number of species have ranged from 100 ..., another tribe with closed leaf sheaths, in their glabrous ovar ...

''Brachyelytrum'' is a genus of North American and East Asian plants in the grass family, classified in its own tribe Brachyelytreae.

Nardeae
''Nardus'' is a genus of plants belonging to the grass family, containing the single species ''Nardus stricta'', known as matgrass. It is placed in its own tribe Nardeae within the subfamily Pooideae. The name derives from ancient Greek ' () from the earlier Akkadian ''lardu''. It is not to be confused with spikenard, ''Nardostachys jatamansi''. Distribution and ecology ''Nardus stricta'' is native to Eurasia (from Iceland and the Azores to Mongolia), North Africa (Algeria, Morocco), and northeastern North America (Greenland, eastern Canada, and the northeastern United States). ''Nardus stricta'' occurs on heath, moorland, hills, and mountains on nutrient poor acidic sandy to peaty soils and is strongly calcifuge, avoiding calcareous soils. It can occur from low elevations to over , becoming a community-dominant in late snow patches on mountains. ''Nardus stricta'' may also become a dominant species in habitats grazed by cattle or sheep because it is tough and unpalatable. It f ...

Poeae
The Poeae are the largest tribe of the grasses, with around 2,500 species in 121 genera. The tribe includes many lawn and pasture grasses. Taxonomy Two separate tribes, Poeae and Aveneae, used to be distinguished based on morphology, but phylogenetic analysis showed that they are intermingled. Poeae now includes the former Aveneae. Phylogenetic analyses identified two lineages based on chloroplast genomes. The genera are classified in 25 subtribes. Reticulate evolution Reticulate evolution, or network evolution is the origination of a lineage through the partial merging of two ancestor lineages, leading to relationships better described by a phylogenetic network than a bifurcating tree.
