- Comments
- Sleepygrass—perennial and cool-season—has been vouchered rather often in the Watershed, from both sides of the Valley. The habitat of Eriocoma robusta ranges from dry foothill meadows up to montane stands of cottonwood and ponderosa. Eriocoma robusta is somewhat toxic to livestock, due to infestation with a fungus. The USA distribution runs down the southern Rockies, from south Wyoming through Colorado to southern New Mexico, in which state the species follows the Rio Grande drainage from north to south, but not into Texas. The specific epithet, "robusta," fits the Watershed plant since it is the tallest of the needlegrasses in the area.
