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.
Aira is a genus of Old World plants in the grass family, native to western and southern Europe, central and southwest Asia, plus Africa.
Andropogon gerardi, known commonly as big bluestem, turkeyfoot, tall bluestem, and bluejoint, is a species of tall grass native to much of the Great Plains and grassland regions of central and eastern North America.
Molinia caerulea, known by the common name purple moor-grass, is a species of grass that is native to Europe, west Asia, and north Africa. It grows in locations from the lowlands up to 2,300 m (7,546 ft) in the Alps. Like most grasses, it grows best in acid soils, ideally pH values of between 3.5 and 5, however, it can continue to live under more extreme conditions, sometimes to as low as 2. It is common on moist heathland, bogs and moorland throughout Britain and Ireland. Introduced populations exist in northeastern and northwestern North America.
Hair grass is a common name for several plants and can refer to:
Lolium perenne, common name perennial ryegrass, English ryegrass, winter ryegrass, or ray grass, is a grass from the family Poaceae. It is native to Europe, Asia and northern Africa, but is widely cultivated and naturalised around the world.
Lambert's Castle is an Iron Age hill fort in the county of Dorset in southwest England. Since 1981 it has been designated as a Site of Special Scientific Interest (SSSI) on account of its geology, archaeology and ecology.
Arrhenatherum elatius, with the common names false oat-grass, tall oat-grass, tall meadow oat, onion couch and tuber oat-grass, is a perennial species of grass, native to Europe, western Asia, and northern Africa.
Danthonia californica is a species of grass known by the common name California oatgrass. This plant is native to two separate regions of the Americas, western North America from California to Saskatchewan, and Chile.
Eragrostis cilianensis is a species of grass known by several common names, including stinkgrass, candy grass, and gray lovegrass.
Aira praecox is a species of grass known by several common names, including early hair-grass, yellow hairgrass and spike hairgrass. It is native to Europe. It also grows in North America as an introduced species, where it can be found on the east and west coasts in sandy or rocky areas, such as beaches and roadsides. This is a tuft-forming annual grass growing up to about 25 centimeters in maximum height. The thin, narrow leaves are located at the base of the stem. It bears very small inflorescences of purple-tinted green bisexual spikelets.
Bothriochloa barbinodis is a species of grass known by the common name cane bluestem. It is native to the Americas, including most of South and Central America, Mexico, and the southernmost continental United States from California to Florida.
Bromus catharticus is a species of brome grass known by the common names rescuegrass, grazing brome, prairie grass, and Schrader's bromegrass. The specific epithet catharticus is Latin, meaning cathartic. The common name rescuegrass refers to the ability of the grass to provide forage after harsh droughts or severe winters. The grass has a diploid number of 42.
Agrostis avenacea is a species of grass known by the common names Pacific bent grass, New Zealand wind grass, fairy grass, or blown-grass. It is native to Australia, New Zealand, and other Pacific Islands including New Guinea and Easter Island.
Digitaria ischaemum is a species of crabgrass known by the common names smooth crabgrass and small crabgrass. It is native to Europe and Asia, but it is known throughout much of the warm temperate world as an introduced species and often a common roadside and garden weed. It is an annual grass producing an inflorescence with two or more narrow branches lined with tiny spikelets.
Airopsis is a genus of southern European and northern African plants in the grass family.
Melinis repens is a species of grass known by the common names rose Natal grass, Natal red top, or simply Natal grass. It is native to southern Africa, but it is well known on other continents such as North America and Australia. However, in the latter continents, it is known as an introduced species and sometimes as a noxious weed. It is an annual or perennial grass which may grow up to a meter tall, and its growth rate is dependent on temperature. The inflorescence is an open array of branches bearing spikelets densely coated in silky white or pink hairs.
Danthonia spicata is a species of grass known by the common name poverty oatgrass, or simply poverty grass. It is native to North America, where it is widespread and common in many areas. The species is distributed across much of Canada and the United States, and its distribution extends into northern Mexico.
Allolee to Walltown is the name given to a Site of Special Scientific Interest (SSSI) in Northumberland, England. The site, which follows the path of a section of Hadrian's Wall, is notable for an unusually wide range of grassland types growing on thin soil above the Whin Sill, a rock formation peculiar to the Northern Pennines.
Sesleria autumnalis, commonly known as autumn moor grass, is a species of grass within the family Poaceae. It is native to southeastern Europe and often used as ornamental ground cover in North America.
