Discussion | D. M. Thompson (2005) observed that two forms of Diplacus layneae co-occur from the Yosemite National Park area southward; one of these is recognized here as D. graniticola. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
Diplacus rupicola is known from Inyo County. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
