Summary Juniperus pinchotii Sudw. was analyzed for areas of population differentiation and possible hybridization with other species of Juniperus, utilizing both morphological and chemical (terpenoid) characters. The volatile terpenoids of the foliage were analyzed by gas chromatography. Numerical methods included: analysis of variance; SNK tests; contour mapping of individual characters; differential systematics; and numerical taxonomy. Juniperus pinchotii appears to be a somewhat variable taxon with some quite divergent populations in the trans‐Pecos region of west Texas where it is morphologically similar to J. monosperma Sarg. No evidence of introgression was detected but some hybridization with J. monosperma in the Palo Duro Canyon of the Texas Panhandle was confirmed.
