Ephedra torreyana
Ephedra torreyana, with common names Torrey's jointfir or Torrey's Mormon tea, is a species of "Ephedra" that is native to the deserts and scrublands of the Southwestern United States (Nevada, Utah, Colorado, Arizona, New Mexico, Texas) and to the State of Chihuahua and northern Mexico. It was originally described by Sereno Watson in 1879 and placed in section "Alatae", "tribe" "Habrolepides" by Otto Stapf in 1889. In 1996 Robert A. Price left "E. torreyana" in section "Alatae" without recognizing a tribe.
