See http://www.calflora.org/cgi-bin/species_query.cgi?where-calrecnum=13225. Note that Calflora follows Jepson in not recognizing any of the former subspecies (search http://ucjeps.berkeley.edu/interchange/index.html for any of the subspecies to see their opinion). If you're concerned about a Jepson bias here, note that FNA and ITIS also don't recognize the subspecies. FNA seems to continue to use Dodecatheon, but notes that a switch to Primula is a relatively recent thing, and note that ITIS also supports the switch to Primula.
