Discussion

Some differences of opinion exist regarding the relationships of Claytonia lanceolata and C. rosea. The work of D. K. Halleck and D. Wiens (1966) and J. S. Shelly et al. (1998) provides ample justification for their recognition as distinct species.

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.
