- Comments
- Pull-up muhly has been recorded only occasionally from the Watershed, around ten times. Except for one observation in the Baca National Wildlife Refuge (2012), all the locations are from the west mountain ranges. Muhlenbergia filiformis, perennial and warm-season, prefers damp conditions in the montane. One voucher came from around the mattress bog at Cumbres pass, collected by William Weber (1965). Also the species tolerates volcanic substrate, and there are a cluster of observations from around Creede (Mineral Co). The USA distribution is all Western states, including New Mexico, where the species follows the Rio Grande drainage only through the first two counties bordering Colorado, no farther down stream. The common name comes from habits of livestock. Cattle jerk the full tuft out of the ground and then spit it out, since they do not like the taste of the roots.
