Members of the iceplant family, Aizoaceae, are appreciated by many people and disliked by some. Farmers value the plants for their browsing stock, hobbyists like to grow and flower mainly the "stone plants" of the family, and tourists enjoy the mass flowering of millions of annuals after good rains in the south western part of South Africa. Only taxonomists show some reservation against members of the Aizoaceae because of the size of the family and the confused and entangled systematics of many groups. For all groups of users, this book will offer some improvements. A worldwide web has been knitted among hundreds of interested people resulting in the pro duction of this lexicon. As a consequence of the expanded collaboration over five continents, innumerable new results can be presented here, including many new delimitations of genera as well as new combinations and names of species. All conclusions are based on thousands of days spent on field work, thousands of original literature references inspected, thousands of herbarium sheets studied, thousands of scanning electron microscopic pictures compared, thousands of photographs taken, and thousands of taxonomic decisions made. As a result of all united efforts, an up-to-date survey of the state of the art can be presented, forming the basis for further research in the family and providing a challenge to every reader to add his special knowledge towards an improved second edition.

About 15 years after the first edition of the Handbook of Aizoaceae, a wealth of changes can be reported for the family Aizoaceae, and this second edition brings a completely new survey over all taxonomic units from subfamilies down to species and subspecies; each critically examined. Of the presently known 2956 species, 1594 have been accepted and are described here, arranged in 147 genera. Six genera have been newly described since 2001, namely Brianhuntleya, Hammeria, Knersia, Phiambolia, Ruschiella, and Volkeranthus, and only one has been placed newly into synonymy (Caulipsilon). All synonymous genus names are treated with the valid genus names. Preliminary molecular studies are referred to, for which different groups of markers at different levels like species, genera, subgenera, and further ranks have been used. The basic division into four subfamilies is supported by more recent studies, yet with some genera being shifted. Furthermore, the geographical distribution of each genus is shown on one map each: either worldwide, or restricted to Southern Africa. For these latter, the main rainfall seasons are delimited by blue lines in order to offer also parameters for cultivation. This second edition provides a comprehensive list of the latest taxonomy including the updated relevant plant data. Following an introduction to the leaf-succulent family Aizoaceae, including keys to the subfamilies and genera, all genera with keys to the subgenera and succulent species are described in detail.
