Name

Thelesperma Less.

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.[2] It also appears that many of the species contain a very similar chromatographic profile, and thus may contain very similar profiles of flavenoids.[3] The genus is closely related to parts of Coreopsis and to certain North American Bidens species (including Bidens coronata and Bidens comosa).[4] Thelesperma species are native to western North America, South America, and Mexico.[1]
