The Loranthaceae are represented in Peru by 11 genera and 63 species (Brako & Zarucchi, 1993; Ulloa Ulloa et al., 2004), mostly shrubs. Here we recognize 14 endemic species in five genera. These endemics grow in a variety of different regions, including Mesoandean, Humid and Dry Puna, and Humid Montane Forest, between 1400 and 4200 m elevation. We applied IUCN categories and criteria to 11 species. Five of these species have been found within the Peruvian protected areas system.
