The research paper "Transfer of Dodecatheon to Primula (Primulaceae)" by Austin Mast and James Reveal in Brittonia 59(1):79-82. 2007, transferred the species of the Genus Dodecatheon into the Genus Primula. This was a controversial move for gardeners, especially those in the North American Rock Garden Society (NARGS) whose symbol is a Dodecatheon. One of the coauthors, James Reveal, wrote about the results of this paper in an article in the Rock Garden Quarterly (the NARGS journal). He explained that previous research by Austin Mast into the evolutionary history of Primula showed that Dodecatheon falls within the Auriculastrum Subgenus (which includes the well known Section Auricula) and is closest to Section Suffrutescens, which has only one member, Primula suffrutescens.

However, this transfer of Dodecatheon isn't universally accepted in the scientific community. The Flora of North America acknowledges this, but keeps Dodecatheon separate while indicating the new names in synonymy. At present I don't include Dodecatheon species in my Species Gallery, though I will likely do so in the future.
