Carex Inops
''Carex inops'' is a species of sedge known as long-stolon sedge and western oak sedge. It is native to northern North America, where it occurs throughout the southern half of Canada and the western and central United States. There are two subspecies; ''Carex inops'' subsp. ''inops'' is limited to the west coast from British Columbia to California, while ''Carex inops'' subsp. ''heliophila'' (sun sedge), is more widespread and is more common east of the Rocky Mountains.Fryer, Janet L. 2009''Carex inops''.In: Fire Effects Information System, nline U.S. Department of Agriculture, Forest Service, Rocky Mountain Research Station, Fire Sciences Laboratory. Description This sedge produces a loose clump of stems up to 50 centimeters tall. The stiff, narrow leaves persist, with dead ones remaining around the base of the plant. The inflorescence usually has pistillate spikes below staminate spikes. [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Herbarium
A herbarium (plural: herbaria) is a collection of preserved plant biological specimen, specimens and associated data used for scientific study. The specimens may be whole plants or plant parts; these will usually be in dried form mounted on a sheet of paper (called ''exsiccatum'', plur. ''exsiccata'') but, depending upon the material, may also be stored in boxes or kept in alcohol or other preservative. The specimens in a herbarium are often used as reference material in describing plant taxon, taxa. Some specimens may be Type (botany), types, some may be specimens distributed in published series called exsiccata, exsiccatae. The term herbarium is often used in mycology to describe an equivalent collection of preserved fungi, otherwise known as a fungarium. A xylarium is a herbarium specialising in specimens of wood. The term hortorium (as in the Liberty Hyde Bailey, Liberty Hyde Bailey Hortorium) has occasionally been applied to a herbarium specialising in preserving material of ...

Pascopyrum Smithii
''Pascopyrum'' is a monotypic genus of grass containing the sole species ''Pascopyrum smithii'', which is known by the common names western wheatgrass and red-joint wheatgrass, after the red coloration of the nodes. It is native to North America. Distribution This is a sod-forming rhizomatous perennial grass which is native and common throughout most of North America. It grows in grassland and prairie in the Great Plains, where it is sometimes the dominant grass species. It is the state grass of North Dakota, South Dakota, and Wyoming. Ecology It is a valuable forage for animals such as bison and black-tailed prairie dogs, and it is good for grazing livestock. It is used for revegetation of disturbed and overgrazed habitat, and many cultivars have been developed to suit various conditions, including low-maintenance lawns. Wheatgrass generally tolerates mowing to four inches, but does not tolerate shade. Healthy stands may crowd out other species, making it more suitable for mono ...

Black Hills
The Black Hills is an isolated mountain range rising from the Great Plains of North America in western South Dakota and extending into Wyoming, United States. Black Elk Peak, which rises to , is the range's highest summit. The name of the range in Lakota is '. It encompasses the Black Hills National Forest. It formed as a result of an upwarping of ancient rock, after which the removal of the higher portions of the mountain mass by stream erosion produced the present-day topography. The hills are so called because of their dark appearance from a distance, as they are covered in evergreen trees. American Indian tribes have a long history in the Black Hills and consider it a sacred site. After conquering the Cheyenne in 1776, the Lakota took the territory of the Black Hills, which became central to their culture. In 1868, the federal US government signed the Fort Laramie Treaty of 1868, establishing the Great Sioux Reservation west of the Missouri River, and exempting the Black ...

Tallgrass Prairie
The tallgrass prairie is an ecosystem native to central North America. Historically, natural and Historical ecology#Anthropogenic fire, anthropogenic fire, as well as grazing by large mammals (primarily bison) provided periodic disturbances to these ecosystems, limiting the encroachment of trees, recycling soil nutrients, and facilitating seed dispersal and germination. Prior to widespread use of the steel plow, which enabled large scale conversion to agricultural land use, tallgrass prairies extended throughout the Midwestern United States, American Midwest and smaller portions of southern Aspen parkland, central Canada, from the transitional ecotones out of eastern North American forests, west to a climatic threshold based on precipitation and soils, to the southern reaches of the Flint Hills in Kansas, to a transition into forest in Manitoba. They were characteristically found in parts of the upper Mississippi River Valley, in the central forest-grasslands transition, the centr ...

Bouteloua
''Bouteloua'' is a genus of plants in the grass family Poaceae. Members of the genus are commonly known as grama grass. Description ''Bouteloua'' includes both annual and perennial grasses, which frequently form stolons. Species have an inflorescence of 1 to 80 racemes or spikes positioned alternately on the culm (stem). The rachis (stem) of the spike is flattened. The spikelets are positioned along one side of the spike. Each spikelet contains one fertile floret, and usually one sterile floret. Taxonomy The genus was first described by Mariano Lagasca in 1805. It was named for Claudio and Esteban Boutelou, 19th-century Spanish botanists. David Griffiths produced a 1912 monograph on the genus. Species Species of ''Bouteloua'' include: * '' Bouteloua alamosana'' Vasey – Mesoamerica * '' Bouteloua americana'' (L.)

Bouteloua Gracilis
''Bouteloua gracilis'', the blue grama, is a long-lived, warm-season ( C4) perennial grass, native to North America. It is most commonly found from Alberta, Canada, east to Manitoba and south across the Rocky Mountains, Great Plains, and U.S. Midwest states, onto the northern Mexican Plateau in Mexico. Blue grama accounts for most of the net primary productivity in the shortgrass prairie of the central and southern Great Plains. It is a green or greyish, low-growing, drought-tolerant grass with limited maintenance. Description Blue grama has green to greyish leaves less than wide and long. The overall height of the plant is at maturity. The flowering stems (culm (botany), culms) are long. At the top are one to four, usually two, comb-like spike (botany), spikes, which extend out at a sharp angle from the flowering stem. Each spike has 20 to 90 spikelets. Each spikelet is long, and has one fertile floret and one or two reduced sterile ones. Below the florets are two gl ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Stipeae
The Stipeae are a tribe of grasses within the subfamily Pooidae, with up to 600 described species. Description The defining morphological features of the Stipeae include single-flowered spikelets lacking a rachilla extension, and the lemmas (the external bract) have either a sharp point or a terminal awn (long bristle). Genera The tribe includes 32 genera: Many species initially placed into ''Stipa'' have now been split off into new genera. Some recent papers have analysed relationships within and between the genera, but a complete analysis has not yet been performed. Stipoid grasses use the C3 photosynthetic pathway and live in temperate areas worldwide. Known fossils date from the late Miocene The Miocene ( ) is the first epoch (geology), geological epoch of the Neogene Period and extends from about (Ma). The Miocene was named by Scottish geologist Charles Lyell; the name comes from the Greek words (', "less") and (', "new") and mea .... References External ...
