Bromus briziformis | |
Bromus briziformis is a species of brome grass known by the common name rattlesnake brome. The specific epithet briziformis comes from the resemblance of the grass to grasses of the genus Briza , particularly Briza maxima . The common name is derived from the resemblance of the spikelets to the rattles of rattlesnakes. The grass has a diploid number of 14.
Bromus briziformis is an annual grass, with erect or ascending culms growing 20–80 cm (7.9–31.5 in) tall. The leaf sheaths are shaggy and ligules, measuring 0.5–2 mm (0.020–0.079 in) long, are densely hairy. The leaf blades are 3–13 cm (1.2–5.1 in) long and 2–4 mm (0.079–0.157 in) wide, and are lightly hairy to glabrous on both sides. The lax and secund panicles have long spreading or drooping branches that bear solitary terminal spikelets. The panicles are 5–15 cm (2.0–5.9 in) long and 3–7 cm (1.2–2.8 in) wide, and the branches are typically longer than the spikelets. The flat spikelets are 15–27 mm (0.59–1.06 in) long and 0.8–1.3 cm (0.31–0.51 in) broad. The glumes are smooth or slightly scabrous. The lower glumes are three to five-veined and 5–6 mm (0.20–0.24 in) long, and the upper glumes are seven to nine-veined and 6–8 mm (0.24–0.31 in) long. The lemmas are ovate or slightly rhombic, have broad translucent margins, and are awnless. The anthers are 0.7–1 mm (0.028–0.039 in) long. The caryopses are as long or shorter than the paleas, and are flat or slightly rolled inwards. [1] [2]
Bromus briziformis grows in waste areas, disturbed areas, and road verges, on dry soils. It is native to southwest Eurasia, but naturalized throughout North America from New Mexico up to southern British Columbia, and scattered throughout the eastern United States. [2]
Bromus arvensis, the field brome, is a brome grass native to Europe and Asia. The specific epithet arvensis is Latin, meaning "of cultivated land".
Bromus hordeaceus, the soft brome, is an annual or biennial species of grass in the true grass family (Poaceae). It is also known in North America as bull grass, soft cheat, and soft chess.
Bromus interruptus, commonly known as the interrupted brome, is a flowering plant in the grass family. It is endemic to southern and central England, which became extinct in the wild in 1972. After several decades in cultivation, the interrupted brome was re-introduced to Aston Rowant National Nature Reserve in 2004, marking the first known re-introduction of an extinct plant in Britain. The plant was a weed of waste places and arable agriculture, particularly of sainfoin cultivation. It can be distinguished from all other Bromus species by its deeply split, or bifid, palea.
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 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 kalmii, the Arctic brome or prairie brome, is a species of brome grass. It is a native bunchgrass in the North-central and Northeastern United States, the Great Lakes region, and eastern Canada. The specific epithet kalmii refers to its discoverer Pehr Kalm.
Hopia obtusa is a species of grass commonly known as vine mesquite. This plant was treated as Panicum obtusum until recently when more molecular and genetic material revealed new information about it. Hopia obtusa is now placed in the monotypic genus Hopia.
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 aleutensis, commonly known as the Aleutian brome, is a perennial grass found in North America. B. aleutensis has a diploid number of 56.
Melica radula is a species of grass endemic to China. It grows on grassy mountain slopes and larch forests at 300–1,200 metres (980–3,940 ft) above sea level.
Bromus latiglumis, the earlyleaf brome, is a grass native to North America. The specific epithet latiglumis is Latin for "broad-glumed", referring to the wide glumes.
Bromus nottowayanus, the Nottoway Valley brome or satin brome, is a brome grass native to North America. The specific epithet nottowayanus refers to the Nottoway Valley. The grass has a diploid number of 14.
Bromus japonicus, the Japanese brome, is an annual brome grass native to Eurasia. The grass has a diploid number of 14.
Bromus squarrosus, the rough brome, is a brome grass native to Russia and Europe. The specific epithet squarrosus is Latin, meaning "with spreading tips". The grass has a diploid number of 14.
Bromus pacificus, the Pacific brome, is a perennial grass native to the Pacific coast of North America. Bromus pacificus has a diploid number of 28.
Glyceria melicaria, the melic mannagrass or northeastern mannagrass, is a perennial grass found in the eastern United States. Its specific epithet melicaria means "similar to Melica". Its diploid number is 40.
Bromus racemosus, the smooth brome or bald brome, is a species of flowering plant in the family Poaceae. It is native to subarctic and temperate Eurasia, and widely introduced elsewhere, including North America, Iceland, the Southern Cone of South America, the Korean Peninsula, Australia, and New Zealand. It grows in alkaline meadows and in waste places.
