It was named for Claudio and Esteban Boutelou, 19th-century Spanish botanists. David Griffiths produced a 1912 monograph on the genus.

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 botanical name, species epithet comes from Latin "shortened" and "hanging". Description Sideoats grama is a warm-season grass. The culm (botany), culms (flowering stems) are tall, and have alternate leaf, 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 spike (botany), 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, an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

David Griffiths (botanist)
David Griffiths (1867–1935) was an early 20th century American agronomist and botanist who was a specialist on fungi and on spermatophytes, seed-producing plants, especially cacti. Biography David Griffiths grew up in Dakota Territory 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 Smut (fungus), 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 ha ...

Central America
Central America is a subregion of North America. Its political boundaries are defined as bordering Mexico to the north, Colombia to the southeast, the Caribbean to the east, and the Pacific Ocean to the southwest. Central America is usually defined as consisting of seven countries: Belize, Costa Rica, El Salvador, Guatemala, Honduras, Nicaragua, and Panama. Within Central America is the Mesoamerican biodiversity hotspot, which extends from southern Mexico to southeastern 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. Most of Central America falls under the Isthmo-Colombian cultural area. Before the Spanish expedition of Christopher Columbus' voyages to the Americas, hundreds of indigenous peoples made their homes in the area. From the year 1502 onwards, Spain ...

Mesoamerica
Mesoamerica is a historical region and cultural area that begins in the southern part of North America and extends to the Pacific coast of Central America, thus comprising the lands of central and southern Mexico, all of Belize, Guatemala, El Salvador, and parts of Honduras, Nicaragua and northwestern part of Costa Rica. As a cultural area, Mesoamerica is defined by a mosaic of cultural traits developed and shared by its indigenous cultures. In the pre-Columbian era, many Indigenous peoples of the Americas, indigenous societies flourished in Mesoamerica for more than 3,000 years before the Spanish colonization of the Americas began on Hispaniola in 1493. In world history, Mesoamerica was the site of two historical transformations: (i) primary urban generation, and (ii) the formation of New World cultures from the mixtures of the indigenous Mesoamerican peoples with the European, African, and Asian peoples who were introduced by the Spanish colonization of the Americas.
