The Genus Lewisia (Kew magazine monograph)

The main concern in this work is with the nineteen species of the genus Lewisia, although hybrids and cultivars of garden origin are also included. The author is well known for his books on bulbous plants and his monographs of Iris, Crocus and Hellebores. This is the first major published revision of the genus since 1966. The last few years have seen an increase in the popularity of lewisias, particularly with those gardeners who specialize in alpines.
