Discussion | The distinction between Erythranthe latidens and E. inflatula sometimes seems arbitrary, perhaps because of gene exchange where they are sympatric in northwestern California. Erythranthe latidens in Oregon is known only from southern Harney County. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
Mimulus acutidens Greene is heterotypic with the South American M. acutidens Reiche, which is a later homonym. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
