COVER: In conjunction with the enclosed paper on Sclerocactus by Kinney and Heil, our cover displays one of the most beautiful of cacti, S.polyancistrus (Engelm. & Big.) Britt. & Rose, native to California and Nevada, its delicately interlaced, multicolored spines and large magenta flowers are its outstanding features. Unfortunately, it is also one of the most difficult cactus species to cultivate and is rarely found in collections. Rob Skillin of Bakersfield, California, photographed this fine specimen in the El Paso Mountains of that state.
