Sorghastrum Nutans
''Sorghastrum nutans'', known as Indiangrass, is a North American prairie grass found in the United States and Canada, especially in the Great Plains and tallgrass prairies. It is sometimes called Indian grass, yellow Indian-grass, or wood grass. 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 ... [...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, hops, 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. 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] |
Andropogoneae
The Andropogoneae, sometimes called the sorghum tribe, are a large tribe of grasses (family Poaceae) with roughly 1,200 species in 90 genera, mainly distributed in tropical and subtropical areas. They include such important crops as maize (corn), sugarcane, and sorghum. All species in this tribe use C4 carbon fixation, which makes them competitive under warm, high-light conditions. Andropogoneae is classified in supertribe Andropogonodae, together with its sister group Arundinelleae. Subdivisions include 12 subtribes, but the position of several genera within them is still unresolved (''incertae sedis''). Hybridisation was probably important in the evolution of the Andropogoneae, and the tribe's systematics are still not completely resolved. From the morphological point of view, the merging of the former subtribe 'Dimeriinae' (having solitary spikelets borne in 'robust' raceme rachis ) into the subtribe Ischaeminae (having paired spikelets borne in 'fragile' raceme rachis) is ...

Panicum Virgatum
''Panicum virgatum'', commonly known as switchgrass, is a perennial warm season bunchgrass native to North America, where it occurs naturally from 55th parallel north, 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 the production of ethanol and butanol. Other common names for switchgrass include tall panic grass, Wobsqua grass, blackbent, tall prairiegrass, wild Agrostis, redtop, thatchgrass, and Virginia switchgrass.

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 orange c ...

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 i ...

Ecoregion
An ecoregion (ecological region) is an ecological and geographic area that exists on multiple different levels, defined by type, quality, and quantity of environmental resources. 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). Ecoregions are also known as "ecozones" ("ecological zones"), although that term may also refer to biogeographic realms. Three caveats are appropriate for all bio-geographic mapping approaches. Firstly, no single bio-geographic fram ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
