Bouteloua
''Bouteloua'' is a genus of plants in the grass family. Members of the genus are commonly known as grama grass. Taxonomy and systematics The genus was named for Claudio and Esteban Boutelou, 19th-century Spanish botanists. David Griffiths produced a 1912 monograph on the genus. Description ''Bouteloua'' includes both annual and perennial grasses, which frequently form stolons. Species have an inflorescence of 1 to 80 racemes or spikes positioned alternately on the culm (stem). The rachis (stem) of the spike is flattened. The spikelets are positioned along one side of the spike. Each spikelet contains one fertile floret, and usually one sterile floret. Distribution ''Bouteloua'' is found only the Americas, with most diversity centered in the southwestern United States. Uses Many species are important livestock forage, especially blue grama.

Blue Grama
''Bouteloua gracilis'', the blue grama, is a long-lived, warm-season ( C4) perennial grass, native to North America. It is most commonly found from Alberta, Canada, east to Manitoba and south across the Rocky Mountains, Great Plains, and U.S. Midwest states, onto the northern Mexican Plateau in Mexico. Blue grama accounts for most of the net primary productivity in the shortgrass prairie of the central and southern Great Plains. It is a green or greyish, low-growing, drought-tolerant grass with limited maintenance. Description Blue grama has green to greyish leaves less than wide and long. The overall height of the plant is at maturity. The flowering stems ( culms) are long. At the top are one to four, usually two, comb-like spikes, which extend out at a sharp angle from the flowering stem. Each spike has 20 to 90 spikelets. Each spikelet is long, and has one fertile floret and one or two reduced sterile ones. Below the florets are two glumes, one long and the ot ...

Bouteloua Curtipendula
''Bouteloua curtipendula'', commonly known as sideoats grama, is a perennial, short prairie grass that is native throughout the temperate and tropical Western Hemisphere, from Canada south to Argentina. The species epithet comes from Latin "shortened" and "hanging". Description Sideoats grama is a warm-season grass. The culms (flowering stems) are tall, and have alternate leaves that are concentrated at the bottom of the culm. The leaves are light green to blue-green in color, and up to across. The flowers bloom in summer and autumn. They consist of compact spikes that hang alternately in a raceme along the top of the culm. The spikes often fall to one side of the stem, which gives the plant its name. There are 10–50 spikes per culm, and in each spike there are three to six spikelets, or rarely as many as 10. Each spikelet is long and consists of two glumes and two florets. One of the florets is fertile, and has colorful orange to brownish red anthers and feathery ...

David Griffiths (botanist)
David Griffiths (1867–1935) was an early 20th century American agronomist and botanist who was a specialist on fungi and on seed-producing plants, especially cacti. Biography David Griffiths grew up in South Dakota after his family emigrated there from his birthplace of Aberystwyth, Wales. He attended South Dakota Agricultural College, receiving both a B.A. (1892) and an MSc (1893) from that institution. For a few years after leaving college, he taught high school science classes. In 1898, he began doctoral studies at Columbia University, focusing on fungi and publishing on such agriculturally important fungal diseases as powdery mildew, ergots, and smuts. After gaining his Ph.D. degree in 1900, he became a professor of botany at the University of Arizona Experiment Station, where he studied desert plants. A year later, he moved to the Bureau of Plant Industry of the United States Department of Agriculture, where he would spend a decade and a half as a specialist on grasses in ...

Mesoamerica
Mesoamerica is a historical region and cultural area in southern North America and most of Central America. It extends from approximately central Mexico through Belize, Guatemala, El Salvador, Honduras, Nicaragua, and northern Costa Rica. Within this region pre-Columbian societies flourished for more than 3,000 years before the Spanish colonization of the Americas. Mesoamerica was the site of two of the most profound historical transformations in world history: primary urban generation, and the formation of New World cultures out of the long encounters among indigenous, European, African and Asian cultures. In the 16th century, Eurasian diseases such as smallpox and measles, which were endemic among the colonists but new to North America, caused the deaths of upwards of 90% of the indigenous people, resulting in great losses to their societies and cultures. Mesoamerica is one of the five areas in the world where ancient civilization arose independently (see cradle of civ ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
South America
South America is a continent entirely in the Western Hemisphere and mostly in the Southern Hemisphere, with a relatively small portion in the Northern Hemisphere at the northern tip of the continent. It can also be described as the southern subregion of a single continent called America. South America is bordered on the west by the Pacific Ocean and on the north and east by the Atlantic Ocean; North America and the Caribbean Sea lie to the northwest. The continent generally includes twelve sovereign states: Argentina, Bolivia, Brazil, Chile, Colombia, Ecuador, Guyana, Paraguay, Peru, Suriname, Uruguay, and Venezuela; two dependent territories: the Falkland Islands and South Georgia and the South Sandwich Islands; and one internal territory: French Guiana. In addition, the ABC islands of the Kingdom of the Netherlands, Ascension Island (dependency of Saint Helena, Ascension and Tristan da Cunha, a British Overseas Territory), Bouvet Island ( dependency of Norway), Pa ...

Central America
Central America ( es, América Central or ) is a subregion of the Americas. Its boundaries are defined as bordering the United States to the north, Colombia to the south, the Caribbean Sea to the east, and the Pacific Ocean to the west. Central America consists of eight countries: Belize, Costa Rica, El Salvador, Guatemala, Honduras, Mexico, Nicaragua, and Panama. Within Central America is the Mesoamerican biodiversity hotspot, which extends from northern Guatemala to central Panama. Due to the presence of several active geologic faults and the Central America Volcanic Arc, there is a high amount of seismic activity in the region, such as volcanic eruptions and earthquakes which has resulted in death, injury, and property damage. In the pre-Columbian era, Central America was inhabited by the indigenous peoples of Mesoamerica to the north and west and the Isthmo-Colombian peoples to the south and east. Following the Spanish expedition of Christopher Columbus' ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
