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 appendiculatum is found throughout California, although never east of the Sierra Nevada, and into southern Oregon. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
