Other: The genus name, “Erigeron”, is from Greek “eri” which means “early” and “geron” which means “old man” because this plant blooms early in the year and the seed's bristles resembles an old man's gray hair. The species name, “utahensis”, means “of or from Utah” in recognition that the type specimen was collected near Kanab, Utah.
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.
