Cover illustration: Haworthia comptoniana is one of the most admired of succulents. Who could resist its tightly compressed rosette with leaves seemingly made of shiny, green, striated quartz? It is rare in habitat, being found at only one or two localities in the Willowmore District of South Africa. For many years it was also exceedingly scarce in cultivation, largely because it seldom offsets. Now seed-raised plants are seen in many collections. We had asked the artist, Gerhard Marx of South Africa, for a painting of a "showy haworthia". Here he has skillfully captured the beauty of H. comptoniana as he saw it in habitat.
