# Muhlenbergia

Muhlenbergia is a genus of plants in the grass family.
The genus is named in honor of the German-American amateur botanist Gotthilf Heinrich Ernst Muhlenberg (1753-1815). Many of the species are known by the common name muhly. The greatest number are native to the southwestern United States and Mexico, but there are also native species in Canada, Central and South America and in Asia.
