Lechuguilla Cave Pearlsian Gulf
''Agave lechuguilla'' (common name in Chihuahua: ''lechuguilla'', meaning "small lettuce") is an ''Agave'' species endemism, found only in the Chihuahuan Desert. The plant flowers once in its life and then dies. Description The plant reproduces most often through underground offshoots, creating large colonies. It also can flower at any time after the plant has reached three to 21 years of age, producing a leafless stalk that can reach in height. The flower clusters are located at the top and are funnel-shaped in purples, reds, and yellows. The plant dies after flowering in May–July. The leaves are long, tough, and rigid, with very sharp, hard points that can easily penetrate clothing and even leather, giving the colloquial name "shin-daggers". Taxonomy Charles Wright (botanist), Charles Wright first collected the plant in 1849 and it was described by John Torrey in 1859. Distribution and habitat It is an indicator species in the Chihuahuan Desert, the only place it is ...

John Torrey
John Torrey (August 15, 1796 – March 10, 1873) was an American botany, botanist, chemist, and physician. Throughout much of his career, he was a teacher of chemistry, often at multiple universities, while he also pursued botanical work, focusing on the flora of North America. His most renowned works include studies of the New York flora, the Mexican Boundary, the Pacific railroad surveys, and the uncompleted ''Flora of North America''. Biography Torrey was born in New York City, the second child of Capt. William and Margaret (née Nichols) Torrey.Robbins, C. C. (1968). John Torrey (1796–1873), His Life & Times. ''Bulletin of the Torrey Botanical Club''. Vol. 95, No. Nov. 6–Dec. 1968, 515–645. Torrey Botanical Club, New York. He showed a fondness for mechanics, and at one time planned to become a machinist. When he was 15 or 16, his father received an appointment to the state prison at Greenwich Village, New York, where he was tutored by Amos Eaton, then a pri ...

Istle
Ixtle, also known by the trade name Tampico fiber, is a stiff plant fiber obtained from a number of Mexican plants, chiefly species of ''Agave'' and ''Yucca''. The principal source is ''Agave lechuguilla'', the dominant ''Agave'' species in the Chihuahuan Desert. ''Ixtle'' is the common name (or part of the common name) of the plants producing the fiber. ''Ixtle'' is also the common name of a species of bromeliad, ''Aechmea magdalenae'', grown in southern Mexico for its silky fibers. Ixtle fiber is used as a substitute for animal bristles in the manufacture of brushes, cords, and lariats. Wrapped with thread, parallel bundles of fiber were used as the boning in corsets. Types Particular kinds of Ixtle include: *''Tula Ixtle'', produced from ''Agave lechuguilla'' or ''Agave univittata''. The name is derived from the town of Tula, also in the Mexican state of Tamaulipas. The fiber is also obtained from the inner leaves, and is long and almost white. *''Jaumave Ixtle'', produ ...

Least Concern Flora Of North America
Comparison is a feature in the morphology or syntax of some languages whereby adjectives and adverbs are inflected to indicate the relative degree of the property they define exhibited by the word or phrase they modify or describe. In languages that have it, the comparative construction expresses quality, quantity, or degree relative to ''some'' other comparator(s). The superlative construction expresses the greatest quality, quantity, or degree—i.e. relative to ''all'' other comparators. The associated grammatical category is degree of comparison. The usual degrees of comparison are the ''positive'', which simply denotes a property (as with the English words ''big'' and ''fully''); the ''comparative'', which indicates ''greater'' degree (as ''bigger'' and ''more fully''); and the ''superlative'', which indicates ''greatest'' degree (as ''biggest'' and ''most fully''). Some languages have forms indicating a very large degree of a particular quality (called ''elative'' in Semiti ...

Taxa Named By John Torrey
In biology, a taxon (back-formation from ''taxonomy''; plural taxa) is a group of one or more populations of an organism or organisms seen by taxonomists to form a unit. Although neither is required, a taxon is usually known by a particular name and given a particular ranking, especially if and when it is accepted or becomes established. It is very common, however, for taxonomists to remain at odds over what belongs to a taxon and the criteria used for inclusion. If a taxon is given a formal scientific name, its use is then governed by one of the nomenclature codes specifying which scientific name is correct for a particular grouping. Initial attempts at classifying and ordering organisms (plants and animals) were set forth in Carl Linnaeus's system in ''Systema Naturae'', 10th edition (1758), as well as an unpublished work by Bernard and Antoine Laurent de Jussieu. The idea of a unit-based system of biological classification was first made widely available in 1805 in the intro ...

Plants Described In 1859
Plants are predominantly photosynthetic eukaryotes of the kingdom Plantae. Historically, the plant kingdom encompassed all living things that were not animals, and included algae and fungi; however, all current definitions of Plantae exclude the fungi and some algae, as well as the prokaryotes (the archaea and bacteria). By one definition, plants form the clade Viridiplantae (Latin name for "green plants") which is sister of the Glaucophyta, and consists of the green algae and Embryophyta (land plants). The latter includes the flowering plants, conifers and other gymnosperms, ferns and their allies, hornworts, liverworts, and mosses. Most plants are multicellular organisms. Green plants obtain most of their energy from sunlight via photosynthesis by primary chloroplasts that are derived from endosymbiosis with cyanobacteria. Their chloroplasts contain chlorophylls a and b, which gives them their green color. Some plants are parasitic or mycotrophic and have lost the ability ...

Flora Of Texas
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 ...

Native Americans In The United States
Native Americans, also known as American Indians, First Americans, Indigenous Americans, and other terms, are the Indigenous peoples of the mainland United States ( Indigenous peoples of Hawaii, Alaska and territories of the United States are generally known by other terms). There are 574 federally recognized tribes living within the US, about half of which are associated with Indian reservations. As defined by the United States Census, "Native Americans" are Indigenous tribes that are originally from the contiguous United States, along with Alaska Natives. Indigenous peoples of the United States who are not listed as American Indian or Alaska Native include Native Hawaiians, Samoan Americans, and the Chamorro people. The US Census groups these peoples as " Native Hawaiian and other Pacific Islanders". European colonization of the Americas, which began in 1492, resulted in a precipitous decline in Native American population because of new diseases, wars, ethni ...

Sport Drink
Sports drinks, also known as electrolyte drinks, are functional beverages whose stated purpose is to help athletes replace water, electrolytes, and energy before, during and especially after training or competition. There are many perceived benefits and questions pertaining to the efficacy of use for sports and fitness performance. At times if used too much, in wrong cases (as most of nutritional items) they may hinder health or performance. The drinks, or some of their ingredients such as sugar, may not be suitable for certain conditions. Categories of sport drinks Sports drinks can be split into three major types: * Isotonic sport drinks contain similar concentrations of salt and sugar as in the human body. *Hypertonic sport drinks contain a higher concentration of salt and sugar than the human body. *Hypotonic sport drinks contain a lower concentration of salt and sugar than the human body. Most sports drinks are approximately isotonic, having between 4 and 5 heaped teaspoons ...

Agave
''Agave'' (; ; ) is a genus of monocots native to the hot and arid regions of the Americas and the Caribbean, although some ''Agave'' species are also native to tropical areas of North America, such as Mexico. The genus is primarily known for its succulent and xerophytic species that typically form large rosettes of strong, fleshy leaves. ''Agave'' now includes species formerly placed in a number of other genera, such as ''Manfreda'', ×''Mangave'', ''Polianthes'' and ''Prochnyanthes''. Many plants in this genus may be considered perennial, because they require several to many years to mature and flower. However, most ''Agave'' species are more accurately described as monocarpic rosettes or multiannuals, since each individual rosette flowers only once and then dies; a small number of ''Agave'' species are polycarpic. Maguey flowers are considered edible in many indigenous culinary traditions of Mesoamerica. Along with plants from the closely related genera ''Yucca'', ''Hes ...
