Discussion | Trifolium ciliolatum is relatively widespread in California and is found in scattered sites in Baja California, Oregon, and Washington. Trifolium ciliatum Nuttall (1848), which pertains here, is a later homonym of T. ciliatum E. D. Clarke (1813). (Discussion copyrighted by Flora of North America; reprinted with permission.) |
Trifolium kingii is widely distributed throughout Utah (S. L. Welsh et al. 2008), is found in Mesa County southward to Dolores County in Colorado, and is found rarely in eastern Nevada. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
