Trifolium repens, the white clover, is a herbaceous perennial plant in the bean family Fabaceae. It is native to Europe, including the British Isles, and central Asia and is one of the most widely cultivated types of clover. It has been widely introduced worldwide as a forage crop, and is now also common in most grassy areas of North America, Australia and New Zealand. The species includes varieties often classed as small, intermediate and large, according to height, which reflects petiole length. The term 'white clover' is applied to the species in general, 'Dutch clover' is often applied to intermediate varieties, and 'ladino clover' is applied to large varieties.
Elymus repens, commonly known as couch grass, is a very common perennial species of grass native to most of Europe, Asia, the Arctic biome, and northwest Africa. It has been brought into other mild northern climates for forage or erosion control, but is often considered a weed.
Pascopyrum is a monotypic genus of grass containing the sole species Pascopyrum smithii, which is known by the common names western wheatgrass and red-joint wheatgrass, after the red coloration of the nodes. It is native to North America.
Elymus canadensis, synonyms including Elymus wiegandii, commonly known as Canada wild rye or Canadian wildrye, is a species of wild rye native to much of North America. It is most abundant in the central plains and Great Plains. It grows in a number of ecosystems, including woodlands, savannas, dunes, and prairies, sometimes in areas that have been disturbed.
Elymus elymoides is a species of wild rye known by the common name squirreltail. This grass is native to most of North America west of the Mississippi River and occurs in a number of ecosystems, from the alpine zone to desert sage scrub to valley grassland.
Pseudoroegneria spicata is a species of grass known by the common name bluebunch wheatgrass. This native western North American perennial bunchgrass is also known by the scientific synonyms Elymus spicatus and Agropyron spicatum. The grass can be found in the United States, Canada, and Mexico from Alaska and Yukon south as far as Sonora and Nuevo León.
Lolium multiflorum is a ryegrass native to temperate Europe, though its precise native range is unknown.
Thinopyrum intermedium, known commonly as intermediate wheatgrass, is a sod-forming perennial grass in the Triticeae tribe of Pooideae native to Europe and Western Asia. It is part of a group of plants commonly called wheatgrasses because of the similarity of their seed heads or ears to common wheat. However, wheatgrasses generally are perennial, while wheat is an annual. It has gained the Royal Horticultural Society's Award of Garden Merit as an ornamental.
Chloris gayana is a species of grass known by the common name Rhodes grass. It is native to Africa but it can be found throughout the tropical and subtropical world as a naturalized species.
Elymus trachycaulus is a species of wild rye known by the common name slender wheatgrass. It is native to much of North America. It grows in widely varied habitats from northern Canada to Mexico, but is absent from most of the southeastern United States.
Sisymbrium loeselii is a species of flowering plant in the family Brassicaceae known by several common names, including small tumbleweed mustard, false London-rocket, throughe(ver:kashmiri) and tall hedge mustard. It is native to Eurasia, and it is known on other continents as an introduced species and in some areas a common roadside weed.
Eriocoma thurberiana is a species of grass known by the common name Thurber's needlegrass. It is native to the western United States, where it occurs from Washington to California and east to Montana and Wyoming.
Elymus lanceolatus is a species of grass known by the common names thickspike wheatgrass and streamside wheatgrass. It is native to North America, where it is widespread and abundant in much of Canada and the western and central United States. There are two subspecies, subsp. lanceolatus occurring throughout the species' range and subsp. psammophilus occurring in the Great Lakes region.
Psathyrostachys juncea is a species of grass known by the common name Russian wildrye. It was formerly classified as Elymus junceus. It is native to Russia and China, and has been introduced to other parts of the world, such as Canada and the United States. Psathyrostachys juncea is a great source of food for grazing animals, as it has high nutrition value in its dense basal leaves, even in the late summer and autumn seasons. This species can grow and prosper in many harsh environments, making it an ideal candidate for improvement as it can grow in areas were farming is difficult. This species is a drought-resistant forage plant and can survive during the cool seasons. It is also a cross-pollinator and is self-sterile. This means that P. juncea cannot self-fertilize; it must find another plant of the same species with which to exchange gametes. Self-sterilization increases the genetic diversity of a species.
Senecio ertterae is a species of flowering plant in the aster family known by the common name Ertter's ragwort. It is endemic to Oregon, United States.
Dichanthelium clandestinum is a species of grass known by the common name deertongue. It is native to eastern North America, including eastern Canada and the eastern United States.
Elymus wawawaiensis is a species of grass known by the common name Snake River wheatgrass. It is native to western North America, where it occurs in the Pacific Northwest. It is native to eastern Washington and Oregon and parts of Idaho.
Panicum coloratum is a species of grass known by the common names kleingrass, blue panicgrass (USA), white buffalograss ; Bambatsi panic, makarikari grass, and coolah grass (Australia). It is native to Africa, and it has been introduced elsewhere, such as the United States and Australia, and bred into many cultivars.
Paspalum vaginatum is a species of grass known by many names, including seashore paspalum, biscuit grass, saltwater couch, silt grass, and swamp couch. It is native to the Americas, where it grows in tropical and subtropical regions. It is found throughout the other tropical areas of the world, where it is an introduced species and sometimes an invasive weed. It is also cultivated as a turfgrass in many places.
Digitaria eriantha, commonly known as digitgrass or Pangola-grass, is a grass grown in tropical and subtropical climates. It grows relatively well in various soils, but grows especially well in moist soils. It is tolerant to droughts, water lodging, suppresses weeds and grows relatively quickly after grazing. This grass demonstrates great potential for farmers in Africa in subtropical and tropical climates, mostly for livestock feed.
