Observation for Taraxacum cordilleranum in BC, Canada. Provide citation to paper that describes the species. Photo identification confirmed by the paper’s author.
As an aside: It drives me crazy that an important paper like the new Taraxacum research you link to in the observation is only available for an exorbitant fee ($40 for a 17-page article) to non-subscribers or those lacking institutional connections. This precludes its wider dispersal to the general scientific and citizen science community.
