Senecio cliffordii from northwestern New Mexico and south-central Utah is included as a synonym of this species in Flora of North America, Vol. 20 (2006), which would greatly extend the range of Spellenberg's groundsel. Deb Trock, who authored the Packera treatment in Flora of North America recently visited populations of Senecio cliffordii in New Mexico and now doubts her placement of it as a synonym of Packera spellenbergii (Bob Sivinski pers. comm. 2007). The NMRPTC decided at its meeting on March 30, 2007, to maintain Packera spellenbergii and Senecio cliffordii as distinct species.
