Abstract

Morphological and molecular analyses of Honduran dwarf mistletoe (Arceuthobium hondurense Hawksworth & Wiens) and Hawksworth's dwarf mistletoe (A. hawksworthii Wiens & C. G. Shaw bis) indicate these taxa are closely related but can be distinguished based on a few morphological differences. They can also be distinguished by their phenology and host range. Because there are only a few morphological differences between these dwarf mistletoes and because the DNA sequences that have been examined for them are nearly identical, Hawksworth's dwarf mistletoe is reclassified as a subspecies of Honduran dwarf mistletoe: Arceuthobium hondurense subsp. hawksworthii (Wiens & C. G. Shaw bis) Mathiasen. It is principally parasitic on Pinus caribaea but also on P. tecunumaii.
