The Poales are a large order of flowering plants in the monocotyledons, and includes families of plants such as the grasses, bromeliads, and sedges. Sixteen plant families are currently recognized by botanists to be part of Poales.
Poaceae or Gramineae is a large and nearly ubiquitous family of monocotyledonous flowering plants 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.
Hordeum is a genus of annual and perennial plants in the grass family. They are native throughout the temperate regions of Africa, Eurasia, and the Americas.
Saccharum is a genus of tall perennial plants of the broomsedge tribe within the grass family.
The Nymphalidae are the largest family of butterflies, with more than 6,000 species distributed throughout most of the world. Belonging to the superfamily Papilionoidea, they are usually medium-sized to large butterflies. Most species have a reduced pair of forelegs and many hold their colourful wings flat when resting. They are also called brush-footed butterflies or four-footed butterflies, because they are known to stand on only four legs while the other two are curled up; in some species, these forelegs have a brush-like set of hairs, which gives this family its other common name. Many species are brightly coloured and include popular species such as the emperors, monarch butterfly, admirals, tortoiseshells, and fritillaries. However, the under wings are, in contrast, often dull and in some species look remarkably like dead leaves, or are much paler, producing a cryptic effect that helps the butterflies blend into their surroundings.
Chusquea is a genus of evergreen bamboos in the grass family. Most of them are native to mountain habitats in Latin America, from Mexico to southern Chile and Argentina.
In biological classification, especially zoology, the type genus is the genus which defines a biological family and the root of the family name.
Paspalum is a genus of plants in the grass family.
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, 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.
Agropyron fragile is a plant species in the family Poaceae.
Elymus is a genus of perennial plants with approximately 150 species in the grass family, related to rye, wheat, and other widely grown cereal grains.
Vulpia is a widespread genus of plants in the grass family, native to many countries around the world and naturalized in many of the nations to which it is not native. It is most common in temperate regions.
Leersia is a genus of plants in the grass family which includes species known generally as cutgrasses.
Coleataenia is a grass genus 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.
Thomas Robert Soderstrom was an American agrostologist His special field of study was the grass family Gramineae or Poaceae. He was Curator of Grasses at the National Museum of Natural History in Washington, DC for some twenty years.
Cleofé Elsa Calderón was an Argentine botanist.
Oryzoideae (syn. Ehrhartoideae) is a subfamily of the true grass family Poaceae. It includes around 120 species in 19 genera, notably 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.
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.
