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 multiscapa has been the source of taxonomic differences of opinion. Local floras have treated the synonymous C. flava as a distinct species (e.g., R. D. Dorn 1977) while one regional flora (C. L. Hitchcock et al. 1955–1969, vol. 2) united it with C. lanceolata. It is treated here as a distinct species based on the electrophoretic and field work of J. S. Shelly (1998) and the author’s examination of type material.
