Poa flabellata, commonly known as tussac grass or just tussac, is a tussock grass native to southern South America, the Falkland Islands, South Georgia and other islands in the South Atlantic. There are also two isolated records from the herbarium at the French Muséum national d'histoire naturelle for the Île Amsterdam in the Indian Ocean.
Chloridoideae is one of the largest subfamilies of grasses, with roughly 150 genera and 1,600 species, mainly found in arid tropical or subtropical grasslands. Within the PACMAD clade, their sister group are the Danthonioideae. The subfamily includes widespread weeds such as Bermuda grass or goosegrass, but also millet species grown in some tropical regions, namely finger millet and teff.
Alopecurus geniculatus is a species of grass known by the common name water foxtail or marsh foxtail. It is native to much of Eurasia and introduced into North America, South America, and Australia. It grows in moist areas.
Oplismenopsis is a genus of South American plants in the grass family. The only known species is Oplismenopsis najada, native to southern Brazil, Uruguay, and northeastern Argentina.
Micraira is the only genus of tribe Micraireae in the grass family, native to Australia.
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.
Muhlenbergia orophila is a grass species native to Guatemala and to Mexico as far north as the Distrito Federal. The type specimen was collected from an alpine meadow at an elevation of approximately 3750 m near the Summit of Sierra de las Cuchumantanes, a remote mountainous area in el Departamento de Huehuetenango in the western part of Guatemala.
Cenchrus distichophyllus is a grass species native to Cuba.
Calamagrostis lapponica, the Lappland reedgrass, is a grass species native to colder parts of the Northern Hemisphere. It has been reported from Scandinavia, Russia, Greenland, Alaska, and every Canadian province and territory except the Maritime Provinces.
Phaenospermatae is a tribe of grasses, subfamily Pooideae, containing a single genus, Phaenosperma. The tribe previously included several other genera, which are now placed in a separate tribe, Duthieeae.
Altoparadisium is a genus of bunchgrass plants in the grass family. The species are native to Brazil and Bolivia in South America.
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.
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.
Zoysieae is a tribe of grasses in subfamily Chloridoideae, with around 250 species in four genera. All species use the C4 photosynthetic pathway.
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.
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.
Cenchrus elegans is a species of plants in the grass family. It is found in Malesia.
