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 bejariense ranges in east-central Texas from Hunt and Lamar counties in the north, southward to Fort Bend and Harris counties, and westward to Travis and Wilson counties; the species is also known from Acadia and Rapides parishes in Louisiana, and Nevada County in Arkansas. L. F. McDermott reduced Trifolium bejariense to T. carolinianum forma bejariense (Moricand) McDermott. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
