''Epidendrum alpicolum'', often called ''Epidendrum alpicola'', is a tropical orchid native to Bolivia, Colombia, Ecuador, Peru,〔http://data.gbif.org/species/16171832〕 and Venezuela at altitudes from 1.8—2.7 km〔herbarium sheets available at http://orchid.unibas.ch/phpMyHerbarium/5245.2/1/Epidendrum/alpicolum/Reichenbach_Heinrich_Gustav/specimen.php〕 == Description == ''Epidendrum alpicolum'' is a sympodial epiphyte with slender, flattened stems, to 0.6 m tall. The stems are covered by tubular sheathes, which bear leaves on the upper part of the stem. The distichous linear-lanceolate leaves are often bilobulate at the apex.〔Schweinfurth "Orchids of Peru Supplement", ''Fieldiana: Botany'' 33(1970)33—34 as "Epidendrum alpicola Reichb.f., Bonpl. 2:110. 1854."〕 The cylindrical, racemose,many-flowered inflorescence erupts from a solitary spathe (sometimes twin spathes) at the apex of the stem, as is typical of the subgenus ''E''. subg. ''Spathium''〔H. G. Reichenbach, "Orchides", nr. 189, in C. Müller, Ed. ''Walpers. Annales Botanices Systematicae'' 6(1861)366, as "EPIDENDRUM ALPICOLUM"〕 The lanceolate-acuminate sepals are wedge shaped at the base: the dorsal 7–12 mm long by as little as 2 mm wide; the laeral sepals slightly larger and asymmetrical at the base. The linear petals are much shorter than the petals. The trilobulate lip is adnate to the column to its apex: cordate at the base, with minute crenulations on the lateral lobes, two calosities at the base, and three or more shallow keels running down the midlobe from near the column apex.
