Larch dwarf mistletoe not found on alpine larch

Abstract

Reports of larch dwarf mistletoe parasitizing alpine larch are based on two collections of this host/parasite combination made by J.R. Weir in Montana during the early 1900s. Examination of host material from these collections indicates that the host is western larch, not alpine larch as previously reported. Attempts to locate larch dwarf mistletoe on alpine larch were unsuccessful, leaving no valid reports of larch dwarf mistletoe on alpine larch.
