Discussion

Claytonia rosea is morphologically distinct from C. lanceolata based on early cytological and ecological study of the two species by D. K. Halleck and D. Wiens (1966) and the author’s review of type material.

Claytonia czukczorum was included by S. L. Welsh (1974) and E. Hultén (1968) as a variety of C. tuberosa. Based upon the author’s study of type material, it is grouped with C. multiscapa.
