Ephedra can escape me, but I can’t escape Ephedra

Taking a short trip to the American southwest, I have discovered my study shrub occurs quite commonly. Although I normally examine Ephedra californica in the Mojave and San Joaquin deserts in my travels, I have found it i the Chihuahuan Desert, Sonoran Desert, Great Basin Desert, and Colorado Plateau.
