Pleuraphis Mutica
''Hilaria mutica'', synonym ''Pleuraphis mutica'', is a species of grass known by the common name tobosa, or tobosa grass. It is native to Northern Mexico, and the Southwestern United States, in Arizona, New Mexico, Oklahoma, and Texas.Uchytil, Ronald. (1988)''Pleuraphis mutica''.In: Fire Effects Information System, nline U.S. Department of Agriculture, Forest Service, Rocky Mountain Research Station, Fire Sciences Laboratory. Retrieved January 15, 2012. Description ''Hilaria mutica'' is perennial grass that is rhizomatous and forms sod. It usually grows tall, sometimes reaching up to . The stems have decumbent bases and erect tops. Most of the stiff, hairless leaves are basal. They are up to long. The bases of the stems come from a thick, woody rootstock and a system of roots that penetrates up to deep in the soil. The inflorescence is a few centimeters long and is white, straw, or purplish. Spikelets are borne in clusters of three. The plant reproduces mainly by spread ...

Samuel Botsford Buckley
Samuel Botsford Buckley (May 9, 1809 – February 18, 1884) was an American botanist, geologist, and naturalist. He graduated from Wesleyan University in 1836. Buckley investigated the botany of the southern United States and discovered many new species of plants and mollusks. The plant genus ''Buckleya'' was named in his honor. He also was the state geologist of Texas (1860–1861); determined the height of Mount Buckley in the Great Smoky Mountains (named in his honor), in North Carolina, and several other summits; and was the scientific editor of the ''State Gazette'' in Austin, Texas Austin is the capital city of the U.S. state of Texas, as well as the seat and largest city of Travis County, with portions extending into Hays and Williamson counties. Incorporated on December 27, 1839, it is the 11th-most-populous city ... (1871-1872). He wrote numerous scientific papers and a book on the trees and shrubs of the United States.

Clay
Clay is a type of fine-grained natural soil material containing clay minerals (hydrous aluminium phyllosilicates, e.g. kaolin, Al2 Si2 O5( OH)4). Clays develop plasticity when wet, due to a molecular film of water surrounding the clay particles, but become hard, brittle and non–plastic upon drying or firing. Most pure clay minerals are white or light-coloured, but natural clays show a variety of colours from impurities, such as a reddish or brownish colour from small amounts of iron oxide. Clay is the oldest known ceramic material. Prehistoric humans discovered the useful properties of clay and used it for making pottery. Some of the earliest pottery shards have been dated to around 14,000 BC, and clay tablets were the first known writing medium. Clay is used in many modern industrial processes, such as paper making, cement production, and chemical filtering. Between one-half and two-thirds of the world's population live or work in buildings made with clay, often ...

Grasses Of Mexico
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, ...

Chloridoideae
Chloridoideae is one of the largest subfamilies of grasses, with roughly 150 genera and 1,600 species, mainly found in arid tropical or subtropical grasslands. Within the PACMAD clade, their sister group are the Danthonioideae. The subfamily includes widespread weeds such as Bermuda grass (''Cynodon dactylon'') or goosegrass (''Eleusine indica''), but also millet species grown in some tropical regions, namely finger millet (''Eleusine coracana'') and teff (''Eragrostis tef''). With the exception of some species in ''Ellisochloa'' and Eleusine indica, most of the subfamily's species use the C4 photosynthetic pathway. The first evolutionary transition from C3 to C4 photosynthesis in the grasses probably occurred in this subfamily, around 32 to 25 million years ago in the Oligocene. Phylogeny Relationships of tribes in the Chloridoideae according to a 2017 phylogenetic classification, also showing the Danthonioideae as sister group: The following genera have not been assigned t ...

Ergotism
Ergotism (pron. ) is the effect of long-term ergot poisoning, traditionally due to the ingestion of the alkaloids produced by the ''Claviceps purpurea'' fungus—from the Latin "club" or clavus "nail" and for "head", i.e. the purple club-headed fungus—that infects rye and other cereals, and more recently by the action of a number of ergoline-based drugs. It is also known as ergotoxicosis, ergot poisoning, and Saint Anthony's fire. Signs and symptoms The symptoms can be roughly divided into convulsive symptoms and gangrenous symptoms. Convulsive Convulsive symptoms include painful seizures and spasms, diarrhea, paresthesias, itching, mental effects including mania or psychosis, headaches, nausea and vomiting. Usually the gastrointestinal effects precede central nervous system effects. Gangrenous The dry gangrene is a result of vasoconstriction induced by the ergotamine-ergocristine alkaloids of the fungus. It affects the more poorly vascularized distal structures, such as ...

Forage
Forage is a plant material (mainly plant leaves and stems) eaten by grazing livestock. Historically, the term ''forage'' has meant only plants eaten by the animals directly as pasture, crop residue, or immature cereal crops, but it is also used more loosely to include similar plants cut for fodder and carried to the animals, especially as hay or silage. While the term ''forage'' has a broad definition, the term ''forage crop'' is used to define crops, annual or biennial, which are grown to be utilized by grazing or harvesting as a whole crop. Common forages Grasses Grass forages include: *'' Agrostis'' spp. – bentgrasses **''Agrostis capillaris'' – common bentgrass **''Agrostis stolonifera'' – creeping bentgrass *''Andropogon hallii'' – sand bluestem *''Arrhenatherum elatius'' – false oat-grass *'' Bothriochloa bladhii'' – Australian bluestem *''Bothriochloa pertusa'' – hurricane grass *''Brachiaria decumbens'' – Surinam grass *''Brachiaria humidicola'' – ...

Bouteloua
''Bouteloua'' is a genus of plants in the grass family. Members of the genus are commonly known as grama grass.

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 ...
