Book Description
The scope of this publication is limited to mappable information about where pines grow naturally at present. We have not tried to relate present distribution to the fossil record, nor have we tried to indicate the ecological and historical factors controlling species distribution. The elevations at which pines grow are mentioned only in the most general terms; this aspect of distribution is intimately related to latitude, topography, and other features of the local environment.

Book 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.
