Bouteloua dactyloides
''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 (''B. gracilis'') over most of the shortgrass prairie.
"Buffalo grass" in North America is not the same species of grass commonly known as 'buffalo' in Australia. It should not be confused with ''Stenotaphrum secundatum'' varieties such as Sir Walter or Palmetto.
==Description==
Buffalograss is a warm-season perennial shortgrass. It is drought-, heat-, and cold-resistant. Foliage is usually high, though in the southern Great Plains foliage may reach . Buffalograss is usually dioecious. Plants are occasionally monoecious, sometimes with perfect flowers. Flower stalks are tall. The male inflorescence is a panicle; the female inflorescence consists of short spikelets borne in burlike clusters, usually with two to four spikelets per bur.
Buffalograss sends out numerous, branching stolons; occasionally it also produces rhizomes. Roots are also numerous and thoroughly occupy the soil. The numerous stolons and roots form a dense sod. Buffalograss roots are finer than those of most plains grasses, being less than in diameter.〔
