On the cover: The Achenback Canyon trail, which is a 10-minute drive from New Mexico State University in Las Cruces, is home to plants such as this Echinomastus intertextus, including the specimen on the cover captured by Root Gorelick, plus many specimens of Mammillaria heyderi, as well as a few plants of Mammillaria meiacantha. Echinocereus chloranthus and E. fendleri can be found right where people park at the trailhead ... don't let it puncture your tires.
