Abstract
A new species of Epidendrum from the northern Peruvian department of Amazonas belonging to the Incomptum group is described and illustrated. Epidendrum olorteguii is similar to E. tamaense but is easily distinguished by having the flowers green to yellow or rarely ivory white, the sepals lanceolate to oblong-lanceolate, acuminate, the petals narrowly elliptic, acuminate, and the lip trilobed, with lateral lobes prominent, transversely sub-rectangular, basal corners narrowly rounded, distal corner widely rounded and the mid-lobe with two obliquely triangular lobes, the sides involute, the apex with a short, thickened, narrowly triangular, reflexed apiculus. Information on its distribution, habitat, phenology, and conservation status are provided. On the other hand, E. olorteguii is also compared with three morphologically similar species, E. incomptum, E. tamaense and E. ornis.
