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. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
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. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
