Comprehensive compendium of all flowers, shrubs and trees which are threatened with extinction. It is divided into various habitat groups, and the plants within these groups are covered on an individual basis. The information provided for each plant includes a general description of the plant and its propagation process, its geographical area of occurrence and, most importantly, an update on the species' status and the reasons for its perilous situation, as well as steps that need to be taken to redress this situation, if possible. References to conservation projects are made throughout, with particular emphasis on progress in Europe.
