Fourteen species of the genus Epidendrum, recently collected in the Área de Conservación Privada La Pampa del Burro (ACPPB), five of them new to science (Epidendrumechinatiantherumsp. nov., E.imazaensesp. nov., E.parvireflexilobumsp. nov., E.rosulatumsp. nov., and E.ochrostachyumsp. nov.), are described and illustrated. The other species include a new record for Peru (E.acrobatesii) and four for the department of Amazonas (E.brachyblastum, E.forcipatum, E.mavrodactylon, and E.tridens). Epidendrumenantilobum is here considered a synonym of Epidendrumbrachyblastum. The type locality of Epidendrumcryptorhachis, originally stated as Ecuador, Guayabamba, is corrected to indicate that it refers to the valley of Guayabamba, Rodríguez de Mendoza, Amazonas, Peru. Our results show the need to continue conducting botanical exploration in the ACPPB as a baseline for subsequent studies, including a full inventory of the orchid diversity.
