Overview

Morphological variation of ponderosa pine, growing north of Mexico, is described. A map shows distributions of five putative races that are analyzed and discussed. Characteristics of branches, shoots, and needles were measured for 10 of fewer trees growing on 147 plots located at 1,500-ft elevation intervals along latitudinal transects.
