Discussion: The taxonomic status of this plant, as well as several other apparently rare members of the genus in New Mexico, is in need of more thorough study. As it now stands, the numerous collections and relatively large range in several mountain ranges indicate that this plant is not particularly rare in New Mexico.
Recommendation: Leave on L4 (too common and/or possibly taxonomic problems).
