The book edited by the Hedbergs is a remarkable achievement from various points of view. It conveys more to the (interested?) reader than its title would suggest. The authors have penetrated so deeply into the botanical aspects of the endeavours towards the conservation of nature, that in this respect it may be called a book of the utmost importance. Many of those who are not familiar with the subject are not likely to expect this of a A.E.T.F.A.T. publication. More than 50 botanists have contributed towards this book. From nearly all African countries south of the Sahara (they constitute a total of more than 40) data have been collected about particular flora-elements as well as the vegetation of every single country. The reader is also well informed about the achievements concerning the conservation and protection of the vegetation, and about what remains to be done in this particular field.
