Bromus tectorum, known as downy brome, drooping brome or cheatgrass, is a winter annual grass native to Europe, southwestern Asia, and northern Africa, but has become invasive in many other areas. It now is present in most of Europe, southern Russia, Japan, South Africa, Australia, New Zealand, Iceland, Greenland, North America and western Central Asia. In the eastern US B. tectorum is common along roadsides and as a crop weed, but usually does not dominate an ecosystem. It has become a dominant species in the Intermountain West and parts of Canada, and displays especially invasive behavior in the sagebrush steppe ecosystems where it has been listed as noxious weed. B. tectorum often enters the site in an area that has been disturbed, and then quickly expands into the surrounding area through its rapid growth and prolific seed production.
Bromus is a large genus of grasses, classified in its own tribe Bromeae. They are commonly known as bromes, brome grasses, cheat grasses or chess grasses. Estimates in the scientific literature of the number of species have ranged from 100 to 400, but plant taxonomists currently recognize around 160–170 species.
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.
Bromus diandrus is a species of grass known by the common names great brome and "ripgut brome".
Bromus sterilis is an annual or biennial species of bromegrass known as barren brome, poverty brome, and sterile brome.
Bromus secalinus is a species of bromegrass known as rye brome. The specific epithet secalinus is Latin, meaning "rye-like". The fruits are hard, rounded glumes that appear superficially similar to the rye grain, which gives the brome its common and scientific name. The grass has a diploid number of 28.
Bromus madritensis is a species of brome grass known by the common name compact brome. The specific epithet madritensis refers to Madrid, Spain. It has a diploid number of 28.
Bromus arizonicus is a species of brome grass known by the common name Arizona brome.
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.
Bromus ciliatus is a species of brome grass known by the common name fringed brome. It is native to most of North America, including most of Canada, most of the United States except for some portions of the South, and northern Mexico. It is a plant of many habitats, including temperate coniferous forest. The specific epithet ciliatus is Latin for "ciliate", referring to the delicate hairs of the leaf blades.
Bromus grandis is a species of brome grass known by the common name tall brome.
Bromus laevipes is a species of brome grass known by the common name Chinook brome.
Bromus orcuttianus is a species of brome grass known by the common name Orcutt's brome.
Bromus vulgaris is a species of brome grass known by the common name Columbia brome.
Bromus maritimus is a species of brome grass known by the common names maritime brome and seaside brome. It is native to the coastal areas of California and Oregon.
Bromus inermis is a species of the true grass family (Poaceae). This rhizomatous grass is native to Europe and considered invasive in North America.
Bromus erectus, commonly known as erect brome, upright brome or meadow brome, is a dense, course, tufted perennial grass. It can grow to 120 centimetres (47 in). Like many brome grasses the plant is hairy. The specific epithet erectus is Latin, meaning "erect". The diploid number of the grass is 56.
Bromus marginatus is a species of grass known by the common name mountain brome. It is native to western North America, and it is used widely for grazing animals and revegetating landscapes.
Bromus sitchenis, the Alaska brome, is a perennial grass native to the North Pacific coast of North America, in woods and banks from Alaska to Oregon. It can grow up to 1.8 m tall, but is often shorter. Leaf blades are elongate, 7–12 mm wide, and as much as 35 cm long. Spikelets 2.5 to 3.5 cm long with between 6 and 12 flowers, awn is 5 to 10 mm long.
Bromus rigidus, the ripgut brome, is a grass native to Eurasia and naturalized in North America. The specific epithet rigidus means rigid or stiff.
