Thelesperma is a genus of flowering plants in the aster family, Asteraceae. Members of the genus are used by a number of the southwestern Native American tribes as a tea, as such it is sometimes called "Navajo Tea," "Hopi Tea," etc. T. megapotamicum contains luteolin. It also appears that many of the species contain a very similar chromatographic profile, and thus may contain very similar profiles of flavenoids. The genus is closely related to parts of Coreopsis and to certain North American Bidens species (including Bidens coronata and Bidens comosa). Thelesperma species are native to western North America, South America, and Mexico.
