Conspectus of the genus Douglasia (Primulaceae) with comments on Douglasia alaskana , an Alaska–Yukon alpine endemic

The endemic North American genus Douglasia has been considered dubiously distinct from its widespread Asiatic relative Androsace, differing primarily in flower color and growth habit. The distinctive nature of Douglasia is reaffirmed here, and the definition of the genus is amplified with additional...
