Thelesperma
Also called Greenthreads
Thelesperma, commonly known as greenthreads, is a genus of annual or perennial herbs and subshrubs found in the Americas. Members of this genus are closely related to some species of Coreopsis and Bidens. The genus is considered to be within the family Asteraceae.
The genus is found from Alberta, (Canada) to north and west Mexico and from Argentina to Uruguay.
Members of the genus are used by a number of the southwestern Native American peoples as an herbal tea. 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.
