Mormon tea ephedra viridis
Ephedra viridis, known by the common names green Mormon tea, green ephedra, and Indian tea, is a species of Ephedra. It is indigenous to the Western United States, where it is a member of varied scrub, woodland, desert, and open habitats. It grows at 900–2,300 metres (3,000–7,500 ft) elevations.

Description
The Ephedra viridis shrub is woody below, topped with many dense clusters of erect bright green twigs. They may yellow somewhat with age.
Nodes along the twigs are marked by the tiny pairs of vestigial leaves, which start out reddish but soon dry to brown or black. Since the leaves are no longer functional, the stems are green and photosynthetic.
Male plants produce pollen cones at the nodes, each under a centimeter long with protruding yellowish sporangiophores. Female plants produce seed cones which are slightly larger and contain two seeds each.
Uses
The drug ephedrine, an antidepressant and decongestant, is made from this and other Ephedra species. A tea can be made by boiling the stems, explaining the common name "green Mormon tea".
