This is the «oca» family and is represented in Peru by four genera and 105 species (Brako & Zarucchi, 1993; Ulloa Ulloa et al., 2004), mainly shrubs and herbs. Here we recognize as endemics 20 species and seven infra-specific taxa in three genera. These endemic taxa are found mainly in Very Humid Montane Forests, Very Humid Premontane Forests and Mesoandean regions, between 700 and 3600 m elevation. Twelve endemic taxa have been recorded in the Peruvian System of Protected Natural Areas.
