Schindleria (Phytolaccaceae) is a small genus of only three species from Peru and Bolivia. Routine identification of recent Peruvian collections has revealed a new species. Schindleria tomentosa Ricketson is described and illustrated, and its conservation status (CRB1D) and phylogenetic relationships are discussed. In addition, three synonyms are lectotypified (Rivina densiflora Kuntze var. flavida Kuntze, S. weberbaueri O. C. Schmidt, and S. glabra H. Walter), and a fourth synonym (Villamilla rosea) is deemed illegitimate.
