Comments

In the Watershed, spike muhly has been vouchered for only four locations, quite different in elevation: Terrace Reservoir (Conejos Co, 1975), near Red Mountain (Conejos Co, 1983), old Cochetopa pass (Saguache Co, 1971), and Oak Springs 8 miles east of Villa Grove (Saguache Co, 1992). This diversity of habitat and elevation is characteristic of Muhlenbergia wrightii. The center of the USA distribution covers only four states: Utah, Wyoming, Arizona, and New Mexico, where the species follows the Rio Grande drainage down through the state, with only one isolated location farther down stream in Terrell Co, Texas.
