We provide descriptions of all species, full specimen citations, and updated keys to genus Polylepis in Ecuador and to the P. pauta and P. sericea complexes in general.enOpenAccessEudicotsMorfologíaTaxonomíaPolylepis humboldtiiP. loxensisP. longipilosaEudicotsMorfologíaTaxonomíaPolylepis humboldtiiP. loxensisP. longipilosa
