Abstract

The high Andean forests harbor great and unique biodiversity. Here, we report a new species of Epidendrum from
Peru. Epidendrum alejandrinae is described, illustrated and compared with the morphologically similar Epidendrum
ochoae, Epidendrum pachydiscum and Epidendrum aida-alvareziae. We performed a systematic review of herbarium
information on the species reported for the Region of Huancavelica and compared the morphological features of the
closest species to rule out possible matches. The new species is characterized by a short, foliate aggregate stems, an
apical pendulous inflorescence formed from the stem, green resupinate flowers opening in succession, the petals and
sepals semi-extended, a 3-lobed lip, lateral lobes obliquely ovoid, median lobe broadly cuneate, bicallose, and four,
obovoid, laterally compressed pollinia. The novelty represents an important record for the flora associated with the
high Andean forest dominated by Polylepis and Gynoxys in central Peru.
