Thelesperma megapotamicum is a perennial species of flowering plant in the aster family known by the common name wild tea[1] and rayless greenthread. It is native to sections of the Americas, including the central United States, where it grows in many types of habitat.

Description

[edit]

It is a perennial herb producing a slender, branching stem 30 to 60 centimeters tall or more. The leaves are narrow, mostly compound with linear or threadlike segments measuring a few centimeters long. The inflorescence bears several flower heads each in a cuplike involucre of phyllaries with purple-tinged, pointed lobes with white edges. The head contains many yellow or orange disc florets, and sometimes one or more yellow ray florets, although these may be absent.

Human uses

[edit]

Native American groups such as the Hopi and Navajo use this plant to make herbal teas, as a medicinal remedy and a yellow dye.[2] The Hopi name for this plant is hohoysi. The plant can be boiled whole until the water turns a rusty color and used as a tea. In addition, the Hopi people also add the plant, along with water, into large glass jars and place in the sun to make sun tea.[3]

It is known as izeets'ósé in Apache.
