Sorrel, also called common sorrel or garden sorrel, is a perennial herbaceous plant in the family Polygonaceae. Other names for sorrel include spinach dock and narrow-leaved dock.
Poa pratensis, commonly known as Kentucky bluegrass, smooth meadow-grass, or common meadow-grass, is a perennial species of grass native to practically all of Europe, North Asia and the mountains of Algeria and Morocco. It is a common and incredibly popular lawn grass in North America with the species being spread over all of the cool, humid parts of the United States, despite the fact that it is not native to North America. The Spanish Empire brought the seeds of Kentucky bluegrass to the New World in mixtures with other grasses. In its native range, Poa pratensis forms a valuable pasture plant, characteristic of well-drained, fertile soil. It is also used for making lawns in parks and gardens and has established itself as a common invasive weed across cool moist temperate climates like the Pacific Northwest and the Northeastern United States. When found on native grasslands in Canada, for example, it is considered an unwelcome exotic plant, and is indicative of a disturbed and degraded landscape.
Brachypodium sylvaticum, commonly known as false-brome, slender false brome or wood false brome, is a perennial grass native to Europe, Asia and Africa. It has a broad native range stretching from North Africa to Eurasia.
Holcus lanatus is a perennial flowering plant in the grass family Poaceae. The specific epithet lanatus is Latin for 'woolly' which describes the plant's hairy texture. Common names include Yorkshire fog, tufted grass, and meadow soft grass. In North America, where it is an invasive species, names include velvet grass and common velvet grass.
Calamagrostis epigejos, common names wood small-reed or bushgrass, is a species of grass in the family Poaceae which is native to Eurasia and Africa. It is found from average moisture locales to salt marsh and wet habitats.
Calystegia sepium is a species of flowering plant in the family Convolvulaceae. It has a subcosmopolitan distribution throughout temperate regions of the North and South hemispheres.
Dactylis glomerata is a species of flowering plant in the grass family Poaceae, known as cock's-foot, also colloquially as orchard grass, or cat grass (due to its popularity for use with domestic cats). It is a cool-season perennial C3 tufted grass native throughout most of Europe, temperate Asia, and northern Africa.
Arrhenatherum elatius is a species of flowering plant in the grass family Poaceae, commonly known as false oat-grass, and also bulbous oat grass, tall oat-grass, tall meadow oat, onion couch and tuber oat-grass. It is native throughout Europe, and also western and southwestern Asia, and northwestern Africa. This tufted grass is sometimes used as an ornamental grass and is sometimes marketed as "cat grass".
Puccinia coronata is a plant pathogen and causal agent of oat and barley crown rust. The pathogen occurs worldwide, infecting both wild and cultivated oats. Crown rust poses a threat to barley production, because the first infections in barley occur early in the season from local inoculum. Crown rusts have evolved many different physiological races within different species in response to host resistance. Each pathogenic race can attack a specific line of plants within the species typical host. For example, there are over 290 races of P. coronata. Crops with resistant phenotypes are often released, but within a few years virulent races have arisen and P. coronata can infect them.
Bromus hordeaceus, the soft brome, is an annual or biennial species of grass in the grass family (Poaceae). It is also known in North America as bull grass, soft cheat, and soft chess.
Elytrigia is a genus of about 20–40 species of grasses, native to temperate regions of the Old World, in Europe, Asia, and northwest Africa. The species are sometimes included in the related genera Agropyron or Elymus, while species in the genera Pascopyrum and Pseudoroegneria are included in Elytrigia by some authors. The genus name has also been spelled Elytrigium.
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 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.
Juncus acutus, the spiny rush, sharp rush or sharp-pointed rush, is a flowering plant in the monocot family Juncaceae. It is native to the Americas, Northern and Southern Africa, Western and Southern Europe and West Asia, and is found in a variety of wet habitats, such as bogs, fens, meadows, and salt marshes, and along the edges of ponds and lakes.
Agrostis gigantea, known by its common names black bent and redtop, is a perennial grass of the Agrostis genus.
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.
Panicum repens is a species of grass known by many common names, including torpedo grass, creeping panic, panic rampant, couch panicum, wainaku grass, quack grass, dog-tooth grass, and bullet grass. Its exact native range is obscure. Sources suggest that the grass is native to "Africa and/or Asia", "Europe or Australia", "Eurasia", "Australia", "Europe, Asia, and Africa", or other specific regions, including the Mediterranean, Israel, and Argentina. It is present in many places as an introduced species and often a noxious weed. It has been called "one of the world's worst weeds."
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.
Alnus alnobetula is a common tree widespread across much of Europe, Asia, and North America. Many sources refer to it as Alnus viridis, the green alder, but botanically this is considered an illegitimate name synonymous with Alnus alnobetula subsp. fruticosa.
