Discussion
Phoradendron juniperinum is often classified as having two subspecies, subspp. juniperinum and libocedri. Subspecies juniperinum is found throughout the species' range as globose infections on various species of Juniperus. The larger, pendent parasites of Calocedrus from California have been recognized as subsp. libocedri. J. Kuijt (2003) argued that this habit could be a host response because intermediate morphologies are known; the two taxa are not recognized here.
