Eleven taxa of dwarf mistletoes (Arceuthobium spp., Viscaceae) are known to occur in the Siskiyou-Klamath Mountain Region of southern Oregon and northern California, making this the region of greatest species diversity of these parasitic flowering plants in the United States. Two species, Arceuthobium monticola and A. siskiyouense, are endemic to this region. This large diversity of dwarf mistletoes is probably a result of the wide variety of coniferous hosts that are available for colonization in the region. Twenty-one of the 22 taxa of Pinaceae occurring in the region are parasitized by one or more dwarf mistletoes to some extent.
