Abstract
Although the dwarf mistletoes (Arceuthobium spp., Viscaceae) are widespread and common parasites of Pinaceae in the United States and Mexico, only five species are known from Central America: Arceuthobium aureum ssp. aureum, A. globosum ssp. grandicaule, A. guatemalense, A. hawksworthii and A. hondurense. Some of these taxa are considered to be among the rarest dwarf mistletoes in the Western Hemisphere. Another species, A. nigrum, has been reported from western Guatemala and Chiapas. As discussed below, we now have morphological and molecular evidence that show a close relationship between the Chiapan population with A. hondurense from Honduras.
