Comments

Senecio eremophilus is adapted to a wide range of vegetative zones in the Watershed, from basin to montane. It has been recorded a few times from the Culebras of the Watershed (e.g., 2023, iNaturalist #200032723) but regularly so from the Rio Grande drainage Cristos of New Mexico. The central USA distribution is Arizona, Utah, New Mexico, and Colorado. It follows the Rio Grande through the entirety of New Mexico but not into Texas. Variations in bractlets and size of the involucre have generated a number of synonyms that are no longer accepted.
