Abstract
A critical review of the Peruvian and Bolivian species of Acalypha L. (Euphorbiaceae) is presented. As a result 41 species (42 taxa) are accepted, 31 from Peru and 28 from Bolivia, and 94 names are considered synonyms. A new species is described and illustrated, A. psamofila, based on Bolivian material. Comprehensive nomenclatural information is supplied and 36 lectotypes and one neotype are designated. An identification key is also provided, as well as original illustrations of six species and distribution maps of all the accepted species.
