--><p>Subspecies tsugense has the broadest host range among all subspecies of <i>Arceuthobium campylopodum</i>. F. G. Hawksworth and D. Wiens (1996) considered <i></i>subsp.<i> tsugense</i> to be a distinct species with two subspecies, subspp. tsugense and mertensianae. Two additional subspecies have been named: subsp. amabilae and subsp. contortae. Although the authors of these subspecies presented evidence of quantitative character variation and differences in phenology and host preferences, all variants are here considered host races of <i></i>subsp.<i> tsugense</i> (and could be treated taxonomically as forms if so desired). The principal hosts of <i></i>subsp.<i> tsugense</i> are <i>Abies amabilis</i>, <i>A. lasiocarpa</i>, <i>A. procera</i>, <i>Pinus contorta</i>, <i>Tsuga heterophylla</i>, and <i>T. mertensiana</i>. Secondary to rare hosts include <i>Abies grandis</i>, <i>Picea breweriana</i>, <i>Picea engelmannii</i>, <i>Picea sitchensis</i>, <i>Pinus albicaulis</i>, <i>Pinus monticola</i>, and <i>Pseudotsuga</i> mertensiana.</p>
