A genus of about 450 species, primarily of the temperate Northern Hemisphere. Mast et al. (2004) show that Dodecatheon is nested within Primula, and is closely related to (and derived from) Primula subgenus Auriculastrum, apparently via a relatively simple alteration of the corolla for buzz-pollination.
