On the cover: This beautiful specimen of Agave pelona was found growing on a craggy limestone ridge in the Sierra El Viejo, located in Sonora, Mexico, one of only four isolated mountain ranges where this species is known to occur. Among its many charms are long dagger-like leaf tips, an absence of teeth along the leaf margins, deep-red flowers, and the leaves’ purple blush, which appears to be genetic, rather than drought-induced. It and a companion plant at this site, Agave zebra, were observed on three recent trips (see this issue) conducted by Gregg Star, Brian Kemble, and Rob Nixon, who captured this image for our cover.
