Calamovilfa Arcuata
''Calamovilfa arcuata'', commonly known as Cumberland sandreed, is a species of flowering plant in the grass family. It is native to the southeastern United States, where it is found in river scour zones. Due to its specialized habitat, it has a highly localized range, found only on the Cumberland Plateau and in the Ouachita Mountains. Natural history This species is found only is a specialized riverine habitat that is kept open by extreme flood scouring events. These flood events naturally occur in high-gradient, rocky rivers, which results in the prevention of large tree growth. This species takes advantage of the prairie-like openings these floods create. Due to its specialized habitat, and low density of populations, ''Calamovilfa arcuata'' is considered imperiled. On the Cumberland Plateau, it is most often found on sandstone cobble where it co-occurs with two other rare plants that are also restricted to this habitat: '' Conradina verticillata'' (Cumberland rosemary) and ''S ...

Poaceae
Poaceae () or Gramineae () is a large and nearly ubiquitous family of monocotyledonous flowering plants commonly known as grasses. It includes the cereal grasses, bamboos and the grasses of natural grassland and species cultivated in lawns and pasture. The latter are commonly referred to collectively as grass. With around 780 genera and around 12,000 species, the Poaceae is the fifth-largest plant family, following the Asteraceae, Orchidaceae, Fabaceae and Rubiaceae. The Poaceae are the most economically important plant family, providing staple foods from domesticated cereal crops such as maize, wheat, rice, barley, and millet as well as feed for meat-producing animals. They provide, through direct human consumption, just over one-half (51%) of all dietary energy; rice provides 20%, wheat supplies 20%, maize (corn) 5.5%, and other grains 6%. Some members of the Poaceae are used as building materials (bamboo, thatch, and straw); others can provide a source of biofuel, ...

Cumberland Plateau
The Cumberland Plateau is the southern part of the Appalachian Plateau in the Appalachian Mountains of the United States. It includes much of eastern Kentucky and Tennessee, and portions of northern Alabama and northwest Georgia. The terms "Allegheny Plateau" and the "Cumberland Plateau" both refer to the dissected plateau lands lying west of the main Appalachian Mountains. The terms stem from historical usage rather than geological difference, so there is no strict dividing line between the two. Two major rivers share the names of the plateaus, with the Allegheny River rising in the Allegheny Plateau and the Cumberland River rising in the Cumberland Plateau in Harlan County, Kentucky. Geography The Cumberland Plateau is a deeply dissected plateau, with topographic relief commonly of about , and frequent sandstone outcroppings and bluffs. At Kentucky's Pottsville Escarpment, which is the transition from the Cumberland Plateau to the Bluegrass in the north and the Pennyril ...

Ouachita Mountains
The Ouachita Mountains (), simply referred to as the Ouachitas, are a mountain range in western Arkansas and southeastern Oklahoma. They are formed by a thick succession of highly deformed Paleozoic strata constituting the Ouachita Fold and Thrust Belt, one of the important orogenic belts of North America. The Ouachitas continue in the subsurface to the northeast, where they make a poorly understood connection with the Appalachians and to the southwest, where they join with the Marathon uplift area of West Texas. Together with the Ozark Plateaus, the Ouachitas form the U.S. Interior Highlands. The highest natural point is Mount Magazine at . The Ouachita Mountains is a Level III ecoregion designated by the Environmental Protection Agency (EPA). The region has been subdivided into six Level IV ecoregions. Etymology Louis R. Harlan claimed that "Ouachita" is composed of the Choctaw words ''ouac'' for "buffalo" and ''chito'' for "large", together meaning "country of large buffa ...

Conradina Verticillata
''Conradina verticillata'' is a flowering shrub in the mint family, found in the Cumberland Plateau. It is also called ''Conradina montana'', Cumberland rosemary or Cumberland false rosemary. It has been classified as a threatened species under the Endangered Species Act since 1991. Physical characteristics Cumberland rosemary is a shrub which grows about 50 cm high. It has needle-like leaves with an aromatic scent that resembles rosemary. Its flowers are lavender, purple, and more rarely, white. They are 1–2 cm long, with darker spots in the center. In profile, the flowers may have an “S” shape due to the curving of the floral cup. Cumberland rosemary has a bilabiate calyx, 7–9 mm long, with a glandular-hairy surface. It may be hard to distinguish individual Cumberland rosemary plants by eye. What looks like separate plants can actually be one sprawling plant. This is because Cumberland rosemary's stems fall over when they grow higher than 30 cm. T ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Solidago Arenicola
''Solidago arenicola '' is a rare species of flowering plant in the family Asteraceae known by the common name Locust Fork goldenrod (after the type locality which is alongside the Locust Fork River in Blount County, Alabama).

Cumberland County, Tennessee
Cumberland County is a county located in the U.S. state of Tennessee. As of the 2010 census, the population was 56,053. Its county seat is Crossville. Cumberland County comprises the Crossville, TN micropolitan statistical area. History Cumberland County was formed in 1856 from parts of Bledsoe, Roane, Morgan, Fentress, Rhea, Putnam, Overton, and White.G. Donald Brookhart,Cumberland County" ''Tennessee Encyclopedia of History and Culture''. Retrieved: 25 June 2013. During the Civil War, the county was nearly evenly split between those supporting the Union and those supporting the Confederacy. In 1787, the North Carolina legislature ordered widening and improvements to Avery's Trace, the trail that ran from North Carolina through Knoxville and what is now Cumberland County to Nashville. They raised funds by a lottery and completed a project that built a wagon road. This slightly improved travel, but still required a bone jarring trip. The road was often muddy and cros ...

Sporobolus
''Sporobolus'' is a nearly cosmopolitan genus of plants in the grass family. The name ''Sporobolus'' means "seed-thrower", and is derived from Ancient Greek word (), meaning "seed", and the root of () "to throw", referring to the dispersion of seeds. Members of the genus are usually called dropseeds or sacaton grasses. They are typical prairie and savanna plants, occurring in other types of open habitat in warmer climates. At least one species ('' S. caespitosus'' from Saint Helena) is threatened with extinction, and another ('' S. durus'' from Ascension Island) is extinct. Uses While some dropseeds, such as prairie dropseed (''Sporobolus heterolepis''), make nice gardening plants, they are generally considered to make inferior pastures, but seeds of at least some species are edible and nutritious; they were used as food, for example, by the Chiricahua Apaches. Other species are reported to be used as famine foods, such as ''Sporobolus indicus'' in parts of the Oromia Region of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Flora Of The Southeastern United States
Flora is all the plant life present in a particular region or time, generally the naturally occurring (indigenous) native plants. Sometimes bacteria and fungi are also referred to as flora, as in the terms ''gut flora'' or '' skin flora''. Etymology The word "flora" comes from the Latin name of Flora, the goddess of plants, flowers, and fertility in Roman mythology. The technical term "flora" is then derived from a metonymy of this goddess at the end of the sixteenth century. It was first used in poetry to denote the natural vegetation of an area, but soon also assumed the meaning of a work cataloguing such vegetation. Moreover, "Flora" was used to refer to the flowers of an artificial garden in the seventeenth century. The distinction between vegetation (the general appearance of a community) and flora (the taxonomic composition of a community) was first made by Jules Thurmann (1849). Prior to this, the two terms were used indiscriminately.Thurmann, J. (1849). ''Essai de Phy ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
