On the cover: Many interesting plants inhabit the arroyos of Mexico’s Sierra La Paila foothills north of Estación Marte, Coahuila. This fat and healthyLophophora williamsii (the maligned Peyote cactus) is obviously at home here. It thrives wedged into the smallest of crevices on fantastically shaped rocks, where it is well adapted to the colors and shapes of its surroundings. More strange succulents can be found in this area, including Grusonia bradtiana, various ocotillos, Epithelantha bokei, and many more. There’s even an echeveria, E. strictiflora, that can survive the hot dry climate—but only in the shade of bushes and rocks high up in the arroyos. Julia Etter and Martin Kristen captured our cover image. More about this, the friendliest of cacti, can be found beginning on page 222, Martin Terry’s second installment on his adventures collecting tissue samples from peyote populations throughout its range.
