Cover illustration: Britton and Rose named several cactus genera after cities: Matucana, Mila (an anagram for Lima) and Oroya, for La Oroya, all towns in Peru. Matucana and Oroya are closely related within the Borzicactus/Cleistocactus alliance, Oroya differing in its short-tubed, non-zygomorphic flower. The several described species seem questionably distinct from the type, O. peruviana, photographed here by John Trager of the Huntington. It is easily cultivated, doing best when well-watered and fertilized; as a sparsely spined, high-altitude species, it also needs cool conditions and some afternoon shade.
