Bluegrass Subfamily
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. Phylogeny Relationships of tribes in the Pooideae according to a 2017 phylogenetic In biology, phylogenetics (; from Greek φυλή/ φῦλον [] "tribe, clan, race", and wikt:γενετικός, γενετικός [] "origin, source, birth") is the study of the evolutionary history and relationships among or within groups o ... classification, also showing the bamboos as sister group: References External links Poaceae subfamilies {{Poaceae-stub ...

Lygeeae
''Lygeum'' is a genus of Mediterranean plants in the grass family. It is placed in its own tribe Lygeeae, which is sister to Nardeae. The only known species is ''Lygeum spartum'', commonly called esparto grass, cord grass or albardine, which is distributed in arid areas around the Mediterranean Sea. It is similar to '' Stipa tenacissima''Garcı́a-Fuentes, A., et al.

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.

Triticeae
Triticeae is a botanical tribe within the subfamily Pooideae of grasses that includes genera with many domesticated species. Major crop genera found in this tribe include wheat (see wheat taxonomy), barley, and rye; crops in other genera include some for human consumption, and others used for animal feed or rangeland protection. Among the world's cultivated species, this tribe has some of the most complex genetic histories. An example is bread wheat, which contains the genomes of three species with only one being a wheat ''Triticum'' species. Seed storage proteins in the Triticeae are implicated in various food allergies and intolerances. Genera of Triticeae Genera recognized in Triticeae according to Robert Soreng et al.: *''Aegilops'' *''Agropyron'' *''Amblyopyrum'' *''Anthosachne'' *'' Australopyrum'' *'' Connorochloa'' *'' Crithopsis'' *'' Dasypyrum'' *'' Douglasdeweya'' *'' Elymus'' (syn.

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 to 400, but plant taxonomists currently recognize around 160–170 species. ''Bromus'' is part of the cool-season grass lineage (subfamily Pooideae), which includes about 3300 species. Within Pooideae, ''Bromus'' is classified in tribe Bromeae (it is the only genus in the tribe). ''Bromus'' is closely related to the wheat-grass lineage (tribe Triticeae) that includes such economically important genera as ''Triticum'' (wheat), ''Hordeum'' (barley) and ''Secale'' (rye). Etymology The generic name ''Bromus'' is derived from the Latin ''bromos'', a borrowed word from the Ancient Greek (). and mean ''oats'', but seems to have referred specifically to ''Avena sativa'' (Hippocrates ''On Regimen in Acute Diseases'' 2.43, Dioscorides Medi ...

''Littledalea'' is a genus of Asian plants in the grass family, native to mountains in China and neighboring countries.Hemsley, William Botting. 1896. 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 .

Brachypodieae
''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. Flimsy upright stems form tussocks. Flowers appear in compact spike-like racemes with 5-25 flowers on each short-stalked spikelet in summer. Leaves are flat or curved. According to an October 18, 2010 issue of "Nature Online" Laura Longo, an archeologist at University of Siena in Italy found evidence of ''Brachypodium'' and cattail (''Typha'' spp.) residues on prehistoric human grinding tools dated 28,000 years ago from Bilancino in central Italy. A related article authored by Anna Revedin, Biancamaria Aranguren, Roberto Becattini, Laura Longo, Emanuele Marconi, Marta Mariotti Lippi, Natalia Skakun, Andrey Sinitsyn, Elena Spiridonova, and Jiří Svoboda, was contemporaneously published in the Proceedings of the National Academy of Sciences of the United States of America and clarifies that the grain ...

Stipeae
The Stipeae are a tribe of grasses within the subfamily Pooidae, with up to 600 described species. Description The defining morphological features of the Stipeae include single-flowered spikelets lacking a rachilla extension, and the lemmas (the external bract) have either a sharp point or a terminal awn (long bristle). Genera The tribe includes 28 genera: Many species initially placed into ''Stipa'' have now been split off into new genera. Some recent papers have analysed relationships within and between the genera, but a complete analysis has not yet been performed. Stipoid grasses use the C3 photosynthetic pathway and live in temperate areas worldwide. Known fossils date from the late Miocene The Miocene ( ) is the first geological epoch of the Neogene Period and extends from about (Ma). The Miocene was named by Scottish geologist Charles Lyell; the name comes from the Greek words (', "less") and (', "new") and means "less recen .... References External li ...

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.
