Aristida Stricta
''Aristida stricta'', known as wiregrass or pineland three-awn grass, is a warm-season grass native to North America. The species dominates understory vegetation in sandhills and flatwoods coastal plain ecosystems of the Carolinas in the Southeastern United States. Its appearance is characterized by villous bristles ( indument) on each side of its midrib and on the back of the involute leaf blade. Taxonomy and etymology The common name of ''Aristida stricta'', wiregrass, gave rise to the naming of the Wiregrass Region in which it is located. The species was first described by André Michaux in 1803. In 1993, the southern population of the species was split off and described as '' Aristida beyrichiana'' because of geographic and morphological differences. The two species were treated as an "''Aristida stricta'' ''sensu lato'' species complex In biology, a species complex is a group of closely related organisms that are so similar in appearance and other features that the b ...

André Michaux
André Michaux (' → ahn- mee-; sometimes Anglicisation, anglicised as Andrew Michaud; 8 March 174611 October 1802) was a French botanist and explorer. He is most noted for his study of North American flora. In addition Michaux collected specimens in England, Spain, France, and even Persia. His work was part of a larger European effort to gather knowledge about the natural world. Michaux's contributions include ''Histoire des chênes de l'Amérique'' (1801; "The Oaks of North America") and ''Flora Boreali-Americana'' (1803; "The Flora of North America") which continued to be botanical references well into the 19th century. His son, François André Michaux, also became an authoritative botanist. Biography Michaux was born in Satory, part of Versailles (city), Versailles, Yvelines, where his father managed farmland on the king's estate. Michaux was trained in the agricultural sciences in anticipation of his one-day assuming his father's duties, and received a basic classical 18 ...

Wiregrass Region
The Wiregrass region, also known as the Wiregrass plains or Wiregrass country, is an area of the Southern United States encompassing parts of southern Georgia, southeastern Alabama, and the Florida Panhandle. The region is named for the native ''Aristida stricta'', commonly known as wiregrass due to its texture. History Ancestors of the Creek Nation were the first humans in the Wiregrass region and retained control of the area until they were forced to cede most of the territory to the United States in the 1814 Treaty of Fort Jackson. The first white settlers were cattle drovers who took advantage of the wiregrass sprouting earlier than other fodder to feed their semi-wild herds. Geography Originally, the wiregrass region touched twenty-three counties from Savannah to the Chattahoochee River. The current region stretches approximately from just below Macon, Georgia and follows the Fall Line west to Montgomery, Alabama. From there it turns south and runs to approximately Washin ...

Flora Of South Carolina
Flora (: floras or florae) is all the plant life present in a particular region or time, generally the naturally occurring ( indigenous) native plants. The corresponding term for animals is ''fauna'', and for fungi, it is ''funga''. Sometimes bacteria and fungi are also referred to as flora as in the terms ''gut flora'' or ''skin flora'' for purposes of specificity. 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 ...

Aristida
''Aristida'' is a very nearly Cosmopolitan distribution, cosmopolitan genus of plants in the Poaceae, grass family. ''Aristida'' is distinguished by having three Awn (Botany), awns (bristles) on each lemma (botany), lemma of each floret. The genus includes about 300 species found worldwide, often in arid warm regions. This genus is among those colloquially called three-awns wiregrass (other), wiregrasses, speargrass (other), speargrasses and needlegrass (other), needlegrasses. The name ''Aristida'' is derived from the Latin "wikt:arista#Latin, arista", meaning "awn". They are characteristic of semiarid grassland. The Wiregrass Region of North America is named for ''Aristida stricta, A. stricta''. Other locales where this genus is an important component of the ecosystem include the Carolina Bays, the sandhills (Carolina), sandhills of the Carolinas, and sandhill, elsewhere, Acacia aneura, Mulga scrub in Australia, and the xeric grasslands around Lake Tur ...

Species Complex
In biology, a species complex is a group of closely related organisms that are so similar in appearance and other features that the boundaries between them are often unclear. The taxa in the complex may be able to hybridize readily with each other, further blurring any distinctions. Terms that are sometimes used synonymously but have more precise meanings are cryptic species for two or more species hidden under one species name, sibling species for two (or more) species that are each other's closest relative, and species flock for a group of closely related species that live in the same habitat. As informal taxonomic ranks, species group, species aggregate, macrospecies, and superspecies are also in use. Two or more taxa that were once considered conspecific (of the same species) may later be subdivided into infraspecific taxa (taxa within a species, such as plant variety (botany), varieties), which may be a complex ranking but it is not a species complex. In most cases, a specie ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
Sensu Lato
''Sensu'' is a Latin word meaning "in the sense of". It is used in a number of fields including biology, geology, linguistics, semiotics, and law. Commonly it refers to how strictly or loosely an expression is used in describing any particular concept, but it also appears in expressions that indicate the convention or context of the usage. Common qualifiers ''Sensu'' is the ablative case of the noun ''sensus'', here meaning "sense". It is often accompanied by an adjective (in the same case). Three such phrases are: * – "in the strict sense", abbreviation ''s.s.'' or ''s.str.''; * – "in the broad sense", abbreviation ''s.l.''; * – "in a relaxed, generous (or 'ample') sense", a similar meaning to ''sensu lato''. Søren Kierkegaard uses the phrase ''sensu eminenti'' to mean "in the pre-eminent r most important or significantsense". When appropriate, comparative and superlative adjectives may also be used to convey the meaning of "more" or "most". Thus ''sensu stricto' ...

Leaf Blade
A leaf (: leaves) is a principal appendage of the stem of a vascular plant, usually borne laterally above ground and specialized for photosynthesis. Leaves are collectively called foliage, as in "autumn foliage", while the leaves, stem, flower, and fruit collectively form the shoot system. In most leaves, the primary photosynthetic tissue is the palisade mesophyll and is located on the upper side of the blade or lamina of the leaf, but in some species, including the mature foliage of ''Eucalyptus'', palisade mesophyll is present on both sides and the leaves are said to be isobilateral. The leaf is an integral part of the stem system, and most leaves are flattened and have distinct upper ( adaxial) and lower (abaxial) surfaces that differ in color, hairiness, the number of stomata (pores that intake and output gases), the amount and structure of epicuticular wax, and other features. Leaves are mostly green in color due to the presence of a compound called chlorophyll whic ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
Poaceae
Poaceae ( ), also called Gramineae ( ), is a large and nearly ubiquitous family of monocotyledonous flowering plants commonly known as grasses. It includes the cereal grasses, bamboos, 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, including staple foods from domesticated cereal crops such as maize, wheat, rice, oats, barley, and millet for people and 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); oth ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
Indumentum
In biology, an indumentum (Latin, literally: "garment") is a covering of trichomes (fine "hairs") on a plant or of bristles (rarely scales) of an insect. Plants The indumentum on plants can have a wide variety of functions, including as anchorage in climbing plants (e.g., '' Galium aparine''), in transpiration control, in water absorption ('' Tillandsia''), the reflection of solar radiation, increasing water-repellency (e.g., in the aquatic fern '' Salvinia''), in protection against insect predation, and in the trapping of insects ('' Drosera'', '' Nepenthes'', '' Stylosanthes''). Plant indumentum types include *hirsute *lanate *pilose *pubescent *scabrous *scurfy *stellate * tomentose *villous Insects The use of an indumentum on insects can be pollen-related as on bees, sensory like whiskers, or for other uses including adhesion and poison.
