Epidendrum cylindrostachys is an epiphytic orchid native to the mountainous rainforest of Colombia and Peru, at altitudes near 2.5 km.

Spathium because the terminal inflorescence erupts through two narrow, ancipitous spathes.

[3] The closely spaced slender stems grow little more than 1 dm tall and are covered from the base by thin, imbricating sheaths.

The inflorescence is a cylindric raceme bearing many small resupinate purple-spotted flowers subtended by very short linear-acute floral bracts.

The fleshy central lobe is lanceolate and obtuse to retuse at the apex.
