The Viscaceae are represented in Peru by two genera and 69 species (Brako & Zarucchi, 1993; Ulloa Ulloa et al., 2004), all parasitic shrubs. Here we recognize 23 endemic species in the genera Dendrophthora and Phoradendron. These endemic species are found mainly in Very Humid Montane Forests and Mesoandean regions, between 2100 and 3600 m elevation. We applied IUCN categories and criteria to 18 species. Two endemic species have been recorded within Peru's protected areas system.
