Post-Pleistocene geographic variation in Juniperus communis in North America
Adams RP and Nguyen S. 2007. Post-Pleistocene geographic variation in Juniperus communis in North America. Phytologia. 89(1):43-57
From the Abstract: "Plants of Juniperus communis L. var. communis, J. C. var. depressa Pursh., J. C. var. megistocarpa Fern. & St. John, J. C. var. saxatilis Pall. were sampled and DNA fingerprinting (RAPDs, Random Amplified Polymorphic DNAs) was performed. Based on 100 RAPD bands, J. communis var. communis and J. c. var. saxatilis from the eastern hemisphere were clearly separated from J. communis in North America. Populations referred to as var. saxatilis from the Pacific northwest did not show alliances with authenitic var. saxatilis from Europe. However, plants with short, curved leaves, and having a white stomatal band about twice as wide as the green margins are allied with J. c. var. jackii Rehdr."
