Comments

Taxanomically New Mexico groundsel is a vexed species. Following BONAP, we place P. tridenticulata and P. neomexicana under P. thurberi. This results in a species found everywhere in Watershed except for the Lower Basin. BONAP shows this enlarged concept of the species as distributed throughout Colorado and most of New Mexico, with extensions into parts of neighboring states. The species follows the Rio Grande drainage to the Mexican border but not farther down stream into Texas. Note that Allred et al. (2020) call most of these records P. neomexicana, in which species they include P. tridentata. Ackerfield (2022) separates P. neomexicana (with tomentose leaves) and P. thurberi (with glabrous leaves) but shows no distribution map for the second.
