Discussion | Orthocarpus tenuifolius is one of the plants first collected by Meriwether Lewis during the Corps of Discovery Expedition. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
Orthocarpus luteus can be distinguished by its golden yellow corollas, with minutely hooked tips on adaxial lips. The Ontario population is not native. The Blackfeet used the leaves of O. luteus to dye skins, hair, and feathers red to reddish brown (A. Johnston 1987). (Discussion copyrighted by Flora of North America; reprinted with permission.) |
