Bouteloua radicosa, colloquially known as purple grama, is a grass species in the grama genus native to the southwestern United States and northern Mexico. [1]
Purple grama is a perennial grass that grows to 80 cm (31 in) tall, with a dense rhizomatous base. It bears inflorescences in panicles that are 10–15 cm (3.9–5.9 in) long and usually have seven to twelve branches. Branches are to 20–30 cm (7.9–11.8 in) long and bear eight to eleven spikelets. Each spikelet bears two florets. The lower floret has a three awned lemma. [2] [3] [1]
B. radicosa may hybridize with Bouteloua repens and Bouteloua williamsii , which could contribute to its apparent diversity. [4]
Purple grama is found between 3,500–7,000 ft (1,100–2,100 m) and prefers desert grasslands or dry rocky slopes. It is present in Arizona, New Mexico, and California. [1] It was introduced to Maine, although it remains uncommon there. [3]
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.
Bouteloua gracilis, the blue grama, is a long-lived, warm-season (C4) perennial grass, native to North America.
Bouteloua is a genus of plants in the grass family. Members of the genus are commonly known as grama grass.
Bouteloua dactyloides, commonly known as buffalograss or buffalo grass, is a North American prairie grass native to Canada, Mexico, and the United States. It is a shortgrass found mainly on the High Plains and is co-dominant with blue grama over most of the shortgrass prairie.
Bromus madritensis is a species of brome grass known by the common name compact brome. The specific epithet madritensis refers to Madrid, Spain. It has a diploid number of 28.
Bouteloua trifida is a species of grass known by the common name red grama. It is native to central and northern Mexico and the Southwestern United States, where it grows in desert scrub and other dry areas.
Bouteloua hirsuta, commonly known as hairy grama, is a perennial short prairie grass that is native throughout much of North America, including the Great Plains and Canadian Prairies region, as well as Mexico and Guatemala.
Hopia obtusa is a species of grass commonly known as vine mesquite. This plant was treated as Panicum obtusum until recently when more molecular and genetic material revealed new information about it. Hopia obtusa is now placed in the monotypic genus Hopia.
Dalea purpurea is a species of flowering plant in the legume family known as purple prairie clover. Native to central north America, purple prairie clover is a relatively common member of the Great Plains and prairie ecosystems. It blooms in the summer with dense spikes of bright purple flowers that attract many species of insects.

The Sierra begins at the Rio Grande at Big Bend National Park and extends southeast for about 72 kilometres (45 mi), reaching a maximum elevation of 2,720 metres (8,920 ft). Part of the Sierra del Carmen is protected in the Maderas del Carmen Biosphere Reserve as part of a bi-national effort to conserve a large portion of the Chihuahua Desert in Mexico and Texas.
