Consisting of 30 genera and 133 species, this is the only Gymnosperm family with world-wide distribution. All species are described with information on nomenclature, types, distribution, ecology, conservation, cited specimens, taxonomic notes, and distribution maps. Introductory chapters deal with history, morphology and anatomy, phylogeny and evolution, and distribution. The beautiful full-page line drawings of every species, expertly executed by the author, are a prime feature of the book.
