Transfer of Dodecatheon to Primula (Primulaceae)

Abstract

Phylogenies inferred from both chloroplast and nuclear DNA regions have placed the small genusDodecatheon (the shooting stars; 17 spp.) among the descendants of the most recent common ancestor ofPrimula (the primroses; ca. 430 spp.). This is congruent with conclusions previously derived from morphology and cytology. We illustrate how failure to formalize this information in the circumscription ofPrimula might have impeded understanding of the evolution of distyly (as seen inPrimula) and buzz-pollination (as seen inDodecatheon). To avoid future confusion, we make new combinations forDodecatheon inPrimula, and erectPrimula sect. Dodecatheon inPrimula subgenusAuriculastrum for the taxa fromDodecatheon.
