"Epidendrum pogonochilum belongs to the 2000 GROUP Nanum SUBGROUP Renzii which is recognized by the branching, Dichaea-like plants, short inflorescences with two pairs of opposite flowers, 1 to 2 small spathes, and a prominent vesicle along the pedicellate ovary. The species is recognized by the pale green flowers with the apical half of the lip wine-red colored, the lip .32 x .24" [8 x 6 mm], ovate somewhat narrowed in the middle and abruptly recurved, margin minutely erose, and the oblong petals, the nectary forms a vesicle wider than the pedicellate ovary. It is very similar to Epidendrum renzii Garay & Dunsterv., which has green to pale greenish brown flowers with purple dots of the dorsal surface of the sepals, lip .14 to .22" x .14 to .16" [3.5 to 5.5 x 3.5 to 4.5 mm], oblong-elliptic, the margins rounded, apex truncate, petals oblanceolate, and the nectary forms a very prominent, scrotum-like vesicle which is about three times higher than the pedicellate ovary, forming a triangle, but narrow, not wider than the pedicel."
