The Liliaceae are represented in Peru by 15 genera (excluding Alstroemeria y Bomarea) and approximately 29 species of herbaceous plants (Brako & Zarucchi, 1993; Ulloa Ulloa et al., 2004). The family includes three genera endemic to Peru: Diamena, Diora and Trichlora. Here we recognize 11 endemic species in five genera. We assigned IUCN threat categories to six species. Half of the endemic species are known from a single locality. Endemic taxa occupy the Dry Subtropical Coastal, and Mesoandean regions, between 600 and 3600 m elevation. Only one endemic species has been found to date in a Peruvian protected area.
