Other: The genus name, “Wyethia”, honors Nathaniel Wyeth (1802-1856), a Massachusetts businessman who led two overland expeditions to Oregon in 1832 and 1834. The botanist Thomas Nutall and the ornithologist John Kirk Townsend accompanied the 2nd expedition, during which Nutall named this plant for Wyeth. The species name,”scabra”, means “rough” referring to the texture of the leaves which feel like sandpaper.
This family is the most advanced and complex of the dicots. The family is rich in oils and resins and is found in every part of the world, but is infrequent in the tropical rainforest. Aquatic or semi-aquatic species are also uncommon.
