Sorghastrum Nutans
''Sorghastrum nutans'', commonly known as either Indiangrass or yellow Indiangrass, is a North American prairie grass found in the central and eastern United States and Canada, especially in the Great Plains and tallgrass prairies. Description Indiangrass is a warm-season perennial bunchgrass. It is intolerant to shade. It grows tall, and is distinguished by a "rifle-sight" ligule where the leaf blade attaches to the leaf sheath. The leaf is about long. It blooms from late summer to early fall, producing branched clusters (panicles) of spikelets. The spikelets are golden-brown during the blooming period, and each contain one perfect floret that has three large, showy yellow stamens and two feather-like stigmas. One of the two glumes at the base of the spikelets is covered in silky white hairs. The flowers are cross-pollinated by the wind. The branches of pollinated flower clusters bend outwards. At maturity, the seeds fall to the ground. There are about 175,000 seeds pe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Wind Pollination
Anemophily or wind pollination is a form of pollination whereby pollen is distributed by wind. Almost all gymnosperms are anemophilous, as are many plants in the order Poales, including grasses, sedges, and rushes. Other common anemophilous plants are oaks, pecans, pistachios, sweet chestnuts, alders and members of the family Juglandaceae (hickory or walnut family). Approximately 12% of plants across the globe are pollinated by anemophily, including cereal crops like rice and corn and other prominent crop plants like wheat, rye, barley, and oats. In addition, many pines, spruces, and firs are wind-pollinated, and. Syndrome Features of the wind-pollination syndrome include a lack of scent production, a lack of showy floral parts (resulting in small, inconspicuous flowers), reduced production of nectar, and the production of enormous numbers of pollen grains. This distinguishes them from entomophilous and zoophilous species (whose pollen is spread by insects and vertebrates r ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Shortgrass Prairie
The shortgrass prairie is an ecosystem located in the Great Plains of North America. The two most dominant grasses in the shortgrass prairie are blue grama (''Bouteloua gracilis'') and buffalograss ('' Bouteloua dactyloides''), the two less dominant grasses in the prairie are greasegrass (''Tridens flavus'') and sideoats grama (''Bouteloua curtipendula''). The prairie was formerly maintained by grazing pressure of American bison, which is the keystone species. Due to its semiarid climate, the shortgrass prairie receives on average less precipitation than that of the tall and mixed grass prairies to the east. The prairie includes lands to the west as far as the eastern foothills of the Rocky Mountains and extends east as far as Nebraska and north into Saskatchewan. The prairie stretches through parts of Alberta, Wyoming, Montana, North Dakota, South Dakota, and Kansas, and passes south through the high plains of Colorado, Oklahoma, Texas, and New Mexico.

Oklahoma
Oklahoma (; Choctaw: ; chr, ᎣᎧᎳᎰᎹ, ''Okalahoma'' ) is a state in the South Central region of the United States, bordered by Texas on the south and west, Kansas on the north, Missouri on the northeast, Arkansas on the east, New Mexico on the west, and Colorado on the northwest. Partially in the western extreme of the Upland South, it is the 20th-most extensive and the 28th-most populous of the 50 United States. Its residents are known as Oklahomans and its capital and largest city is Oklahoma City. The state's name is derived from the Choctaw words , 'people' and , which translates as 'red'. Oklahoma is also known informally by its nickname, " The Sooner State", in reference to the settlers who staked their claims on land before the official opening date of lands in the western Oklahoma Territory or before the Indian Appropriations Act of 1889, which increased European-American settlement in the eastern Indian Territory.

Longleaf Pine
The longleaf pine (''Pinus palustris'') is a pine species native to the Southeastern United States, found along the coastal plain from East Texas to southern Virginia, extending into northern and central Florida. In this area it is also known as "yellow pine" or "long leaf yellow pine", although it is properly just one out of a number of species termed yellow pine. It reaches a height of and a diameter of . In the past, before extensive logging, they reportedly grew to with a diameter of . The tree is a cultural symbol of the Southern United States, being the official state tree of Alabama. Contrary to popular belief, this particular species of pine is not officially the state tree of North Carolina. Description The bark is thick, reddish-brown, and scaly. The leaves are dark green and needle-like, and occur in bundles of mainly three, sometimes two or four, especially in seedlings. They often are twisted and in length.

Panicum Virgatum
''Panicum virgatum'', commonly known as switchgrass, is a perennial warm season bunchgrass native to North America, where it occurs naturally from 55°N latitude in Canada southwards into the United States and Mexico. Switchgrass is one of the dominant species of the central North American tallgrass prairie and can be found in remnant prairies, in native grass pastures, and naturalized along roadsides. It is used primarily for soil conservation, forage production, game cover, as an ornamental grass, in phytoremediation projects, fiber, electricity, heat production, for biosequestration of atmospheric carbon dioxide, and more recently as a biomass crop for ethanol and butanol. Other common names for switchgrass include tall panic grass, Wobsqua grass, blackbent, tall prairiegrass, wild redtop, thatchgrass, and Virginia switchgrass. Description Switchgrass is a hardy, deep-rooted, perennial rhizomatous grass that begins growth in late spring. It can grow up to high, but is typ ...

Schizachyrium Scoparium
''Schizachyrium scoparium'', commonly known as little bluestem or beard grass, is a species of North American prairie grass native to most of the contiguous United States (except California, Nevada, and Oregon) as well as a small area north of the Canada–US border and northern Mexico. It is most common in the Midwestern prairies and is one of the most abundant native plants in Texas grasslands. Little bluestem is a perennial bunchgrass and is prominent in tallgrass prairie, along with big bluestem (''Andropogon gerardi''), indiangrass (''Sorghastrum nutans'') and switchgrass (''Panicum virgatum''). It is a warm-season species, meaning it employs the C4 photosynthetic pathway. Description Little bluestem grows to become an upright, roundish mound of soft, bluish-green or grayish-green blades in May and June that is about two to three feet high. In July, it initiates flowering stalks, which reach four to five feet in height. In fall, it displays a coppery or mostly orang ...

Andropogon Gerardi
''Andropogon gerardi'', commonly known as big bluestem, is a species of tall grass native to much of the Great Plains and grassland regions of central and eastern North America. It is also known as tall bluestem, bluejoint, and turkeyfoot. Taxonomy ''Andropogon gerardi'' was formally named in 1792 by Fulgenzio Vitman. It was named for French botanist Louis Gérard, who had first described the plant from specimens that had been cultivated in Provence, France. Kew's International Plant Names Index and USDA Germplasm Resources Information Network reject the spelling ''gerardii'' and provide reasoning for ''gerardi'' as being the correct spelling for the specific epithet of this taxon. ''Andropogon gerardii'' still makes appearances in various literature, including other USDA publications. Description Big bluestem is a perennial warm-season bunchgrass. It is tolerant of a wide range of soil conditions. The main roots are deep, and the plants send out strong, tough rhizomes, so ...

Ecoregion
An ecoregion (ecological region) or ecozone (ecological zone) is an ecologically and geographically defined area that is smaller than a bioregion, which in turn is smaller than a biogeographic realm. Ecoregions cover relatively large areas of land or water, and contain characteristic, geographically distinct assemblages of natural communities and species. The biodiversity of flora, fauna and ecosystems that characterise an ecoregion tends to be distinct from that of other ecoregions. In theory, biodiversity or conservation ecoregions are relatively large areas of land or water where the probability of encountering different species and communities at any given point remains relatively constant, within an acceptable range of variation (largely undefined at this point). Three caveats are appropriate for all bio-geographic mapping approaches. Firstly, no single bio-geographic framework is optimal for all taxa. Ecoregions reflect the best compromise for as many taxa as possible. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
