| Bromus arvensis | |
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 arvensis is an annual or biennial grass with erect culms growing 0.3–0.9 m (1 ft 0 in – 2 ft 11 in) tall. The grass has an extensive fibrous root system. The leaf sheaths are softly pubescent and leaf blades are pubescent on both faces. The leaf blades are 10–20 cm (3.9–7.9 in) long and 2–6 mm (0.079–0.236 in) wide. The obtuse ligules are 1–1.5 mm (0.039–0.059 in) long. The large, open panicles are 10–30 m (33–98 ft) long and 4–20 cm (1.6–7.9 in) wide, with ascending branches that droop at their ends. The straight or slightly curved branches are typically longer than the spikelets. The lanceolate spikelets are 1.5–3 cm (0.59–1.18 in) long and become purplish at maturity. The spikelets have long pedicels and are five to twelve flowered. The bases of florets can be concealed or obvious at maturity. The glumes are glabrous. The lower glumes are three-veined and 4–6 mm (0.16–0.24 in) long, and the upper glumes are five-veined and 5–8 mm (0.20–0.31 in) long. The obtuse and glabrous or slightly scabrous lemmas are 7–8 mm (0.28–0.31 in) long and 1.1–1.5 mm (0.043–0.059 in) wide, and have seven faint nerves. The margins are translucent and end in lengthy and acute teeth. The awns are straight and 7–10 mm (0.28–0.39 in) long. The anthers are approximately 4 mm (0.16 in) long. The caryopses are shorter than the paleas and can be either weakly or strongly rolled inwards. [1] [2]
The grass flowers in June and July.
Bromus arvensis grows along roadsides, in disturbed areas, and in fields. It is native to southern and central Europe, but is now naturalized as a weed throughout temperate regions including North America and Asia. The grass is a soil improver and is useful for erosion control. [2] [3]
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 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 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 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, Kalm's 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 longiflora is a grass species in the family Poaceae that is endemic to Chile where it can be found from Coquimbo to Talca.
Oplismenus thwaitesii is a flowering plant that is endemic to India.
Melica serrana, is a species of grass endemic to Cerro de las Ánimas, Uruguay.
Melica pappiana is a species of grass found in China. It grows on grassy mountain slopes and larch forests at 500–2,000 metres (1,600–6,600 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.
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.
