The Malpighiaceae are represented in Peru by 21 genera and over 145 species (Brako & Zarucchi, 1993; Ulloa Ulloa et al., 2004), mostly lianas and vines. Here we recognize 26 endemic taxa in 12 genera. These endemics are found mainly in the Humid Lowland Amazonian Forests and Very Humid Montane Forests regions, between 120 and 2600 m elevation. We applied IUCN categories and criteria to 21 taxa. Four taxa have been recorded within Peru's protected areas system.
