Serpentine subgroup are greenish, brownish, or spotted minerals commonly found in serpentinite. They are used as a source of magnesium and asbestos, and as decorative stone. The name comes from the greenish color and smooth or scaly appearance from the Latin serpentinus, meaning "snake-like".
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.
Serpentinite is a metamorphic rock composed predominantly of one or more serpentine group minerals formed by near to complete serpentinization of mafic to ultramafic rocks. Its name originated from the similarity of the texture of the rock to that of the skin of a snake. Serpentinite has been called serpentine or serpentine rock, particularly in older geological texts and in wider cultural settings.
The genus Phenacomys is a group of North American voles. The genus name comes from the Greek for "imposter mouse."
Serpentine soil is an uncommon soil type produced by weathered ultramafic rock such as peridotite and its metamorphic derivatives such as serpentinite. More precisely, serpentine soil contains minerals of the serpentine subgroup, especially antigorite, lizardite, and chrysotile or white asbestos, all of which are commonly found in ultramafic rocks. The term "serpentine" is commonly used to refer to both the soil type and the mineral group which forms its parent materials.
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 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.
Camissonia benitensis is a species of evening primrose known by the common names San Benito suncup and San Benito evening primrose. It is endemic to the Diablo Range of the South Coast Ranges of California, where its range includes far southern San Benito County, far western Fresno County, and far eastern Monterey County.
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 lanceolatus, the Mediterranean brome, large-headed brome or lanceolate brome, is a species of flowering plant in the family Poaceae. It is native to the Mediterranean, the Middle East, the Caucasus, Central Asia, Xinjiang in China, Afghanistan and Pakistan. A tetraploid, it does well in disturbed habitats and has been introduced to scattered locations in North America, South America, and central Europe.
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 lepidus, the slender soft brome, is a species of flowering plant in the family Poaceae. It has a disjunct distribution, native to central and northern Europe, and Xinjiang in China, and introduced to an assortment of other locales, including some northeast states of the United States, the Canary Islands, and Egypt. The taxonomic history of this species has been marked by nomenclatural issues.
Bromus danthoniae, the oat brome or three-awned brome, is a species of flowering plant in the family Poaceae, native to Turkey, Cyprus, the Caucasus region, the Middle East, Central Asia, Afghanistan, Pakistan, the western Himalayas, and Tibet. It is rarely discovered growing in other locations, but apparently not in sustained populations. It grows in a wide variety of habitats, and shows morphological variation due to the differing conditions in those habitats.
Bromus biebersteinii, the meadow bromegrass or just meadow brome, is a species of flowering plant in the family Poaceae, native to the Caucasus, Iraq, Iran and Afghanistan. It has been developed as a forage in North America and there are a number of cultivars available, including 'Arsenal', 'Cache', 'Fleet', 'MacBeth', 'Montana', 'Paddock' and 'Regar'.
