On the cover: The distinctive flower of Epiphyllum baueri Dorsch, a new species published in this issue. As epiphyllums are rather large and conspicuous plants, new species are now rarely discovered, the last one (E. laui) being published in 1990. E. baueri is distinguished by its reflexed tepals and clustered fascicle of stamens that closely surround the style. Photo: Ralf Bauer.
