Description
A summary of the nomenclature and 22 distribution maps of subdivisions of the genus Pinus L., pine, are presented here to supplement Miscellaneous Publication 991--Geographic Distribution of the Pines of the world, with maps of 94 species. Important synonyms and lists of the species are included, and the slight changes in the classification of the subdivisions are explained. The maps of subdivisions combined from those of individual species show clearly and graphically the maximum natural range of all component species. These compiled maps of groups of related species may be useful in further researches, particularly in classification, geographical distribution, tree breeding and introduction, and evolution.
