Herrickia kingii (D. C. Eaton) Brouillet

Comments

Herrickia kingii is known only from the Wasatch and Canyon mountains. The generic assignment of this species has been debated (e.g., A. Cronquist and D. D. Keck 1957; G. L. Nesom 1991e; Cronquist 1994). S. L. Welsh et al. (1987) underlined similarities with "Aster" alpigenus (= Oreostemma alpigena), among others. A recent molecular phylogenetic analysis (L. Brouillet et al. 2004) showed that H. kingii belongs to the Eurybia complex, possibly as a basal member of Herrickia.
