In Flora of North America, Volume 20 (2006), all the varieties of Grindelia arizonica were submerged into a single variable species without recognition of subspecific taxa. The NMRPTC notes the subjectivity involved in taxonomic decisions within this complex and will continue to consider G. arizonica var. neomexicana to be a distinct entity. In discussions at the 2007 New Mexico Rare Plant Technical Council Meeting, Council members concluded that G. arizonica var. neomexicana represents a population of plants that is geographically defined and sufficiently distinct from other closely related populations that it deserves taxonomic recognition.
