On the cover: Framed by the remains of a cylindropuntia, Dudleya anthonyifinds home well-hidden in thick brush in the Socorro Canyon, Baja California Norte, Mexico. The strikingly farinose leaves and unusual size (38 cm across) attracted the attention of the photographers, Julia Etter and Martin Kristen, during the early stage of flowering in May. This special issue of the journal is dedicated to Dudleya, a large genus in the Crassula family. Plants of this genus occur in a well-defined area between southern Oregon and the southern tip of the Baja peninsula, extending east only as far as Arizona. Most of the species have a small area of distribution and are known to hybridize readily (but, unlike the other North American Crassulaceae, only with other dudleyas). Their variability and hybridization make this genus difficult for taxonomic classification, Reid Moran, well-known expert on this genus, admits that more intensive study must to be conducted in order to clarify Dudleya nomenclature. People interested in Dudleya soon find out that there are not many publications available, and quality illustrations of plants in their natural habitat are scarce. We hope our approach, with a strong focus on habitat, travel and horticulture makes for a compelling introduction to these fascinating plants.
