The Aloineae, a tribe of several hundred species of succulent plants of the lily family, are ideal subjects for the study of karotypes and chromosome irregularities. This book brings together the major findings of a half-century of study of the Aloineae, with regard to polyploidy, aneuploidy, deletions, duplications, inversions, and translocations in the group. The possible evolutionary effects of ecological relationships, natural hybridization, and morphological changes during growth are also assessed. Illustrations include maps, diagrams, photographs, photomicrographs, and electron micrographs.

The Illustrated Handbook of Succulent Plants represents the first comprehensive taxonomic treatment of succulents in thirty years. It covers over 9000 taxa of all succulents except Cactaceae. The Crassulaceae (stonecrop family) volume presents the first complete treatment of the family for many decades. The family is a very diverse group, and plants range from tiny insignificant annual herbs to perennial shrubs and trees. Many of the species have attractive flowers. The entire family consists of 33 genera and 23 hybrid genera with a total of 1410 species and 305 infraspecific taxa. The largest genus is Sedum (stonecrop, wallpepper) with 428 species. Other large genera are Aeonium (36), Crassula (195), Dudleya (47), Echeveria (139), Kalanchoe (144), Rhodiola (58), Sempervivum (63), and Tylecodon (46). A key to all genera is included. The descriptions of all accepted taxa are supplemented with typification and distribution data, full synonymy, literature references and 341 colour photos.

Found in a variety of forms, cacti and other succulents have elicited widespread interest and tremendous popularity worldwide. Although the subject of a certain amount of debate, about 10,000 species are recognized as belonging to the succulent group. Of these, an estimated 2,000 are threatened with global extinction in the wild and many more are regionally or nationally threatened mainly due to habitat destruction and collection for international trade.This Action Plan brings together from around the world current information on population status, threats and conservation of this particularly important group of plants. Prepared with conservationists, scientists, governments, protected area managers and grant-awarding bodies in mind, it suggests priorities for action and encourages collaboration among interested parties at all levels.
