"Epidendrum pucunoense belongs to the GROUP Alpicolum characterized by the simple, cane-like stems, long, narrow 1 to 3 spathaceous bracts, fox-tail-like inflorescence and numerous flowers with fleshy lip. The species is recognized by the small flowers, the sepals prominently midveined when dry, the large orbicular lateral lobes of the lip, larger in surface than the midlobe, and the emarginate, entire, prominent clinandrium, the leaves are narrowly elliptic and acute. It is close to Epidendrum zosterifolium which has sepals .2 to .28" [5 to 7 mm] long, greenish white f1owers, with the middle near the apex of sepals and lip deep green, lateral lobes of the lip small and erose, the prominent funnel-shaped, bilobed, erose clinandrium, a strong, daytime, spicy fragrance, leaves oblong, bilobed."
