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.
Bromus kalmii is a perennial grass, with solitary or slightly tufted culms that grow 0.4–1.2 m (1 ft 4 in – 3 ft 11 in) tall. The culms are pubescent just below the nodes. The grass typically has three to five and occasionally six leaf blades. The firm and scabrous leaf blades are either pubescent or glabrous and are 7–17 cm (2.8–6.7 in) long and 4–10 mm (0.16–0.39 in) wide. The glabrous or sometimes shaggy sheaths are mostly shorter than the internodes and each have a V-shaped cleft. The ligule is typically 0.5 mm (0.020 in) long. The narrow, crowded panicle is 5–15 cm (2.0–5.9 in) long. The lower branches of the panicle are very slender and each bear one or two spikelets. The five to eleven flowered spikelets are 1.4–2.6 cm (0.55–1.02 in) long and 5–6 mm (0.20–0.24 in) wide. Both glumes have short, adpressed hairs. The lower glume is three-nerved and the upper glume is five-nerved. The densely hairy lemmas are oblong to elliptical in shape, and have straight awns 1–3 mm (0.039–0.118 in) long. The oblong and flat palea is slightly shorter than the glume. The anthers are approximately 2 mm (0.079 in) long. [2] [3]
The grass flowers from July to through August. [4]
Bromus kalmii grows in dry or moist open areas or thickets, especially on calcareous soils. [2] [5]
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 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 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.
Festuca occidentalis is a species of grass known as western fescue. It is native to much of the northern half of North America and is most widely distributed in the west. It is most often found in forest and woodland habitat. The specific epithet occidentalis is Latin, meaning "western".
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 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.
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 rigidus, the ripgut brome, is a grass native to Eurasia and naturalized in North America. The specific epithet rigidus means rigid or stiff.
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.
Puccinellia fasciculata, or Borrer's saltmarsh grass, is an annual grass native to coasts of Europe and introduced to the northern east coast of North America. Its diploid number is 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.
Bromus texensis, the Texas brome, is an annual grass native to Texas.
