Abstract
We present a monograph of the high Andean tree genus Polylepis (Rosaceae), based on a species concept considering morphological, climatic and biogeographic distinctness as indicators of evolutionary independence. In total, we recognize 45 species of Polylepis, grouped in five sections. Polylepis sect. Sericeae is represented by 15 species in four subsections, P. sect. Reticulatae by seven species, P. sect. Subsericantes by three species, P. sect. Australes by two species and P. sect. Incanaee by three subsections with 18 species. We describe seven new species, one from Colombia (P. frontinensis), one from Ecuador (P. simpsoniae) and five from Peru (P. acomayensis, P. fjeldsaoi, P. occidentalis, P. pilosissima and P. sacra). Three species from Peru (P. albicans, P. pallidistigma and P. serrata) are re-instated as valid species. Two taxa from Bolivia (P. incanoides and P. nana) are elevated from subspecies to species rank. The morphology, habitat, distribution, ecology and conservation status of each species are documented. We also provide an identification key to the species of the genus and general introductions on taxonomic history, morphology, evolution, ecology and conservation

MK first wishes to thank T. Mischler and J. Fjeldså for introducing him to the delights of birds associated with Polylepis forests during his school age, thus creating a fascination for these forests that has lasted since then. Early work of MK on the genus was supported by his PhD advisor H. Ellenberg, as well as S.G. Beck, P. Driesch, I. Hensen and S. Lægaard. Since then, collaborations with F. Ames, C. Aucca, M. Baader, V. Camel, A. Cierjacks, A. Domic, F. Heitkamp, D. Hertel, S.K. Herzog, S. Hohnwald, V. Horna, H. Jungkunst, A. Kühn, M. Kumar, S. & G. Miehe, H. Quispe, D. Renison, K. Romoleroux, K. Ruokolainen, M.J. Sanín, A. Schmidt-Lebuhn, C. Segovia-Sal-cedo, P. Seltmann, V.G. Solíz Neffa, S. Steudel, M. and S.P. Sylvester, J. Toivonen and K. Wesche, amongst many others, have ensured that his interest in Polylepis never had a chance to falter. TEBE thanks E.G. Urquiaga, C. Alvarez, A. Cahuana, D. Lopez and C. Medina for their support during fieldwork. Our work would have been impossible without all the plant collectors and herbarium curators (AAU, COL, CUZ, F, GOET, HUA, LOJA, MEDEL, MERF, MO, NY, QCA, US, USM, VEN and Z/ZH) who made specimens (physical or digital) available for study. We would also like to thank H. Quispe, K. Romoleroux and V. Popp for direct collaboration on the present study. We acknowledge all colleagues who contributed specimens or photographs, including, M. Cellini, G. Guzman and D. Reninson in Argentina, A. Domic, A. Fuentes, E. Gareca and J. Quisbert in Bolivia, H. Agudelo-Zamora, D. Cabrera, F. Cardona, F. Fajardo, A. Möhl, M.J. Sanin and J.M. Velez in Colombia, E. Bastidas and J. Peña in Ecuador; C. Aucca, W. Arque, A. Bustamante, J. Chambi, C. Florencio, M. Marca, W.
