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.
Agropyron is a genus of Eurasian plants in the grass family), native to Europe and Asia but widely naturalized in North America.
Aegilops is a genus of Eurasian and North American plants in the grass family, Poaceae. They are known generally as goatgrasses. Some species are known as invasive weeds in parts of North America.
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.
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.
Elymus hystrix, known as eastern bottlebrush grass, or bottle-brush-grass, is a bunchgrass in the grass family, Poaceae. It is native to the Eastern United States and Eastern Canada.
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 central and western North America.
Pseudoroegneria spicata is a species of perennial bunchgrass known by the common name bluebunch wheatgrass. It is native to western North America.
Leymus arenarius is a psammophilic (sand-loving) species of grass in the family Poaceae, native to the coasts of Atlantic and Northern Europe. Leymus arenarius is commonly known as sand ryegrass, sea lyme grass, or simply lyme grass.
Sporobolus foliosus is a species of grass known by the common name California cordgrass. It was reclassified from Spartina foliosa after a taxonomic revision in 2014. It is native to the salt marshes and mudflats of coastal California and Baja California, especially San Francisco Bay. It is a perennial grass growing from short rhizomes. It produces single stems or clumps of thick, fleshy stems that grow up to 1.5 meters tall. They are green or purple-tinged. The long, narrow leaves are flat or rolled inward. The inflorescence is a narrow, dense, spike-like stick of branches appressed together, the unit reaching up to 25 centimeters long. The lower spikelets are sometimes enclosed in the basal sheaths of upper leaves.
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.
Elymus hoffmannii is a species of grass known by the common name RS wheatgrass. It was described as a new species in 1996. It became known to science when some grasses were collected in Turkey in 1979 and one type was successfully bred out, proving to be a natural hybrid. E. hoffmannii is derived from this hybrid between Elymus repens and the bluebunch wheatgrasses of Turkey, such as Pseudoroegneria spicata.
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.
Hystrix was a formerly recognized genus of grass.
Elymus caninus, the bearded couch or bearded wheatgrass, is a species of flowering plant in the family Poaceae that is native to Europe including the UK but can be found introduced in the US states of Oregon and Washington. E. caninus has been observed in two morphotypes; the first population being "pauciflorum," with the second being "caninus."
Elymus texensis, commonly called Texas wildrye, is a species of flowering plant in the grass family (Poaceae). It is native to United States, where it is endemic to the Edwards Plateau of Texas. Its natural habitat is on calcareous bluffs in Juniperus woodlands and grassy areas.
Elymus svensonii, commonly called Svenson's wildrye, is a species of flowering plant in the grass family (Poaceae). It is native to United States, where it is endemic to the Interior Low Plateau of Kentucky and Tennessee. Its natural habitat is on dry, rocky, limestone river bluffs.
Elymus villosus is a species of wild rye known by the common names silky wild rye, downy wild rye, or hairy wild rye. It is native to eastern North America.
Dichanthelium lindheimeri, commonly called Lindheimer panicgrass, is a species of flowering plant in the grass family (Poaceae). It is native primarily to eastern areas the United States and Canada, with its range extending into the South Central region. There are also outlying western populations in California, New Mexico and Oregon.
