Poaceae tribes

The Bambuseae are the most diverse tribe of bamboos in the grass family (Poaceae). They consist of woody species from tropical regions, including some giant bamboos. Their sister group are the small herbaceous bamboos from the tropics in tribe Olyreae, while the temperate woody bamboos (Arundinarieae) are more distantly related. The Bambuseae fall into two clades, corresponding to species from the Neotropics (subtribes Arthrostylidiinae, Chusqueinae, and Guaduinae) and from the Paleotropics (subtribes Bambusinae, Hickeliinae, Melocanninae, and Racemobambosinae).

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.

Oryzeae is a tribe of flowering plants in the true grass family, Poaceae. It contains 11 genera, including both cultivated rice (Oryza) and wild rice (Zizania).

The Andropogoneae, sometimes called the sorghum tribe, are a large tribe of grasses (family Poaceae) with roughly 1,200 species in 90 genera, mainly distributed in tropical and subtropical areas. They include such important crops as maize (corn), sugarcane, and sorghum. All species in this tribe use C4 carbon fixation, which makes them competitive under warm, high-light conditions.

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 i

Arundinarieae is a tribe of bamboo in the grass family (Poaceae) containing a single subtribe, Arundinariinae, and 31 genera. These woody bamboos occur in areas with warm temperate climates in southeastern North America, Subsaharan Africa, South Asia and East Asia. The tribe forms a lineage independent of the tropical woody bamboos (Bambuseae) and the tropical herbaceous bamboos (Olyreae).

Cynodonteae is a large tribe of grasses in the subfamily Chloridoideae, with over 800 species.

Olyreae is a tribe of grasses in the bamboo subfamily (Bambusoideae). Unlike the other two bamboo tribes, Olyreae are herbaceous and do not have a woody stem. Their sister group are the tropical woody bamboos (Bambuseae).

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.

The Stipeae are a tribe of grasses within the subfamily Pooidae, with up to 600 described species.

Ehrharteae is a tribe in the grass family, comprising four genera.

Eragrostideae is a tribe of grasses in subfamily Chloridoideae. It contains roughly 500 species, which all use the C4 photosynthetic pathway.

Steyermarkochloeae is a tribe of the Panicoideae subfamily in the grasses (Poaceae), native to tropical South America. There are only two species in two genera, Arundoclaytonia and Steyermarkochloa. The tribe probably belongs to a basal lineage within the subfamily. Species in this tribe use the C3 photosynthetic pathway.

Arundineae is a tribe of grasses, containing four genera.

Cyperochloeae is a small tribe of grasses in the Panicoideae subfamily, found in Australia. It has only two species in two monotypic genera, Cyperochloa and Spartochloa. Cyperochloeae is sister to the tribe Thysanolaeneae. These two tribes, together with the Centotheceae, Steyermarkochloeae, Tristachyideae, Zeugiteae, and Chasmanthieae, form a monophyletic clade that is sister to the rest of the Panicoideae. They use the C3 photosynthetic pathway.

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. Its other genera are Koordersiochloa, Lycochloa, Pleuropogon, Schizachne, and Triniochloa.

Arundinelleae is a tribe of grasses with roughly 90 species in three genera, mainly distributed in tropical and subtropical areas. The tribe's sister group are the Andropogoneae, with which they are classified in supertribe Andropogonodae. All species in this tribe use C4 carbon fixation.

Isachneae is a tribe of tropical and subtropical grasses in subfamily Micrairoideae, with around 120 species in six genera.

Centotheceae is a small tribe of grasses with six species in two genera, distributed in Africa and Asia. It belongs to a group within the subfamily Panicoideae, sometimes referred to as "centothecoid clade", which consists of the tribes Thysanolaeneae, Cyperochloeae, Centotheceae, Chasmanthieae, Zeugiteae, Tristachyidae, and Steyermarkochloeae; this clade is sister to the remaining groups within Panicoideae. Unlike many other clades in the subfamily Panicoideae, they use the C3 photosynthetic pathway.

The Aristideae is the sole tribe of grasses in the monotypic subfamily Aristidoideae of the true grass family Poaceae. Its members are herbaceous annuals or perennials found in the tropics, subtropics and temperate zones. The tribe has over 300 species in three genera: The subfamily is a member of the PACMAD clade of grasses, the evolutionary group in which C4 photosynthesis independently evolved a number of times.

Phyllorachideae is a tribe in the grass family, comprising two genera. It may be better placed as a subtribe of Oryzeae.

Molinieae is a tribe of grasses, containing 11 genera, including reed (Phragmites) and moor-grass (Molinia).

Chasmanthieae is a small tribe of grasses in the subfamily Panicoideae. It belongs to a basal lineage within the subfamily and has only seven species in two genera, Bromuniola with one species in Africa and Chasmanthium from North America. They all use the C3 photosynthetic pathway.

Diarrheneae is a tribe of grasses, containing two genera.

Eriachneae is a tribe of grasses in subfamily Micrairoideae, with 50 species in two genera. Species in the tribe use the C4 photosynthetic pathway and are distributed mainly in Australasia, reaching into Asia and Micronesia.

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.

Zeugiteae is a tribe of the subfamily Panicoideae in the grasses (Poaceae), native to Africa, Asia, Australasia, South and Central America. There are 18 species in four genera.

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.

Tristachyideae is a tribe of the Panicoideae subfamily in the grasses (Poaceae), native to tropical and subtropical regions of Africa, Asia, and South America. There are around 70 species in eight genera. The tribe belongs to a group within the subfamily Panicoideae, sometimes referred to as "centothecoid clade", which consists of the tribes Thysanolaeneae, Cyperochloeae, Centotheceae, Chasmanthieae, Zeugiteae, Tristachyidae, and Steyermarkochloeae; this clade is sister to the remaining groups within Panicoideae.

Centropodieae is a tribe of grasses containing only two genera. It is the earliest-branching lineage in the subfamily Chloridoideae and contains its only genus with C3 species, Ellisochloa, while all other species in the tribe and subfamily use the C4 photosynthetic pathway.

Triraphideae is a small tribe of tropical grasses, containing about 15 species in three or four genera. Like most of the subfamily Chloridoideae, species in the tribe use the C4 photosynthetic pathway.
