Epidendrum curimarcense (Orchidaceae), a new species from Central Peru

A new species of Epidendrum from Peru, Epidendrum curimarcense, is described, illustrated and compared with the similar species Epidendrum ampelospathum. The new finding represents an important record for the flora associated with Polylepis forests of central Peru. The species has stems produced from a middle internode of the previous cane-like stem, a spathe, an elongate peduncle with several similar spaced bracts, flowers opening in succession, petals narrower than the sepals, a 3-lobed lip which is bicallose with rounded sub-equal lobes, and 4 obovoid, laterally compressed pollinia.
