The serpentine subgroup are greenish, brownish, or spotted minerals commonly found in serpentinite rocks. They are used as a source of magnesium and asbestos, and as a decorative stone. The name is thought to come from the greenish color being that of a serpent.
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.
The Shire of Serpentine-Jarrahdale is a local government area in the outer southeastern metropolitan area of Perth, the capital of Western Australia, and has an area of 905 square kilometres (349 sq mi) and a population of almost 27,000 as at the 2016 Census. The Shire's seat of government is the town of Mundijong.
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 rock composed of one or more serpentine group minerals, the name originating from the similarity of the texture of the rock to that of the skin of a snake. Minerals in this group, which are rich in magnesium and water, light to dark green, greasy looking and slippery feeling, are formed by serpentinization, a hydration and metamorphic transformation of ultramafic rock from the Earth's mantle. The mineral alteration is particularly important at the sea floor at tectonic plate boundaries. Serpentinite has been called serpentine or serpentine rock, particularly in older geological texts and in wider cultural settings.
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.
Stenocarpus is a genus of about 22 species of flowering plants in the family Proteaceae. They are trees or shrubs with variably-shaped leaves, zygomorphic, bisexual flowers, the floral tube opening on the lower side before separating into four parts, followed by fruit that is usually a narrow oblong or cylindrical follicle.
A leaf miner is any one of numerous species of insects in which the larval stage lives in, and eats, the leaf tissue of plants. The vast majority of leaf-mining insects are moths (Lepidoptera), sawflies, and flies (Diptera). Some beetles also exhibit this behavior.
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 sterilis is an annual or biennial species of bromegrass known as barren brome, poverty brome, and sterile brome.
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 California, where its range includes far southern San Benito County, far western Fresno County, and far eastern Monterey County.
Symphyotrichum depauperatum, commonly known as serpentine aster or starved aster, is a rare species in the family Asteraceae adapted to serpentine barrens, an ecosystem with a high concentration of toxic metals in the soil. It has been found in Pennsylvania, Maryland, and on some diabase glades in North Carolina. It grows to 50 centimeters and has white ray florets surrounding a center of yellow disk florets.
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 tomentellus, the wooly brome, is a species of flowering plant in the family Poaceae, native to Crete, Turkey, the Caucusus, the Levant, Iraq, Iran, and Turkmenistan. It is a regionally important livestock forage species.
Bromus grossus, the whiskered brome, is a species of flowering plant in the family Poaceae. It is native to central Europe, and has been introduced to Great Britain, and New York and Oregon in the United States. It has gone extinct in the Netherlands. During the Neolithic it arose as a weed of spelt fields, and due to changing agricultural practices is now considered highly endangered under the Habitats Directive.
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.
