New and noteworthy species of the genus Epidendrum (Orchidaceae, Laeliinae) from the Área de Conservación Privada La Pampa del Burro, Amazonas, Peru

Abstract

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 (Epidendrum echinatiantherum sp. nov., E. imazaense sp. nov., E. parvireflexilobum sp. nov., E. rosulatum sp. nov., and E. ochrostachyum sp. 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). Epidendrum enantilobum is here considered a synonym of Epidendrum brachyblastum. The type locality of Epidendrum cryptorhachis, 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.
