Abstracto
The taxonomically difficult genus Polylepis (Rosaceae) contains several problematic species complexes, including one around P. sericea. We here reevaluate species boundaries in this complex based on morphological characters and climatic niches. We recognize five species within the P. sericea complex, based primarily on leaf characters: P. albicans (northwestern Peru), P. argentea (central Peru) described here, P. canoi (southeastern Peru to central Bolivia), P. ochreata (Ecuador to southernmost Colombia), and P. sericea (Venezuela to central Colombia). We provide full synonymy, diagnostic notes, lists of selected specimens examined, and a key to the species of the complex.
Descripción
This work would not have been possible without the work of all the plant collectors and herbarium curators (AAU, COL, CUZ, F, GOET, MERF, MO, NY, US, USM, VEN, and Z/ZH) who made specimens (physical or digital) available for study. We thank Katya Romoleroux and one anonymous reviewer who have improved the manuscript with their suggestions and helpful comments. HRQM thanks Vladimir Camel, Wendy Navarro, and Fressia Ames for their support during field work. We thank the Servicio Nacional Forestal y de Fauna Silvestre for providing research authorizations under the R.D.G. No 233-2015, No 237-2015, No 037-2017-SERFOR/DGGSPFFS. TEBEs work was funded by FONDECYTCONCYTEC (No227-2014-FONDECYT). HRQMs work was possible thanks to grant CONCYTEC, Project 149-2015-FONDECYT-DE.
