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 spreading ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Samuel Botsford Buckley
Samuel Botsford Buckley (May 9, 1809 – February 18, 1884) was an American botanist, geologist, and naturalist. Buckley was born in Torrey, New York, on May 9, 1809. He graduated from Wesleyan University in 1836. He received a Ph.D. from Waco University in 1872. 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. Buckley determined the height of several summits in the Great Smoky Mountains, including Mount Buckley which was named in his honor. Buckley served as an assistant to Texas chief geologist Benjamin Franklin Shumard. He named an oak species after Shumard in 1860, but then stymied Shumard's reappointment under newly-elected Governor Sam Houston. Buckley was the Texas state geologist from 1860 to 1861 and 1874 to 1877. He was the scientific editor of the ''State Gazette'' in Austin, Texas Austin ( ) is the List of capitals in the United S ...

Clay
Clay is a type of fine-grained natural soil material containing clay minerals (hydrous aluminium phyllosilicates, e.g. kaolinite, ). 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. Clays develop plasticity (physics), plasticity when wet but can be hardened through Pottery#Firing, firing. Clay is the longest-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 radiocarbon dating, dated to around 14,000 BCE, and Clay tablet, clay tablets were the first known writing medium. Clay is used in many modern industrial processes, such as paper making, cement production, and chemical filtration, filtering. Between one-half and two-thirds of the world's population live or work in buildings made with clay, often baked into brick, as an essenti ...

Grasses Of Mexico
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 families, 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 forage, feed for livestock, 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, an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Chloridoideae
Chloridoideae is one of the largest subfamily, subfamilies of Poaceae, grasses, with roughly 150 genera and 1,600 species, mainly found in arid tropical or subtropical grasslands. Within the PACMAD clade, their sister group is the Danthonioideae. The subfamily includes widespread weeds such as Bermuda grass (''Cynodon dactylon''), goosegrass (''Eleusine indica'') or finger grass (''Chloris (plant), Chloris''), 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 carbon fixation, C4 photosynthetic pathway. The first evolutionary transition from C3 photosynthesis, C3 to C4 photosynthesis in the grasses probably occurred in this subfamily, around 32 to 25 million years ago in the Oligocene.

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 Ergotism is the effect of long-term ergot poisoning. The symptoms can be roughly divided into convulsive symptoms and gangrenous symptoms. Ergot alkaloids, the active compounds produced by the ergot fungus, can cause severe vasoconstriction, leading to symptoms like gangrene and convulsions. Additionally, ergot alkaloids can mimic neurotransmitters and hormones in the human body, causing hallucinations and affecting hormonal balance. Chronic exposure to ergot alkaloids has been linked to reproductive issues, such as spon ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

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'' – kor ...

Flourensia Cernua
''Flourensia'' is a genus of flowering plants in the family Asteraceae. It contains subshrubs and shrubs, which are commonly known as tarworts. They are found in the southwestern United States, Mexico, and central South America (Bolivia and northern Argentina). The genus name honours French physiologist Jean Pierre Flourens (1794–1867). Phylogenetic studies found that the genus as previously circumscribed was polyphyletic, and in 2023 many of the South American species were placed in the new genus ''Austroflourensia''.Freire SE, Ospina JC, Aagesen L, Espinar LA, Panero JL, Scataglini MA.

Bouteloua
''Bouteloua'' is a genus of plants in the grass family Poaceae. 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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
