"Epidendrum pirrense belongs to the GROUP Pseudepidendrum SUBGROUP Paniculatum which has caespitose plants, cane-like stems, apical inflorescence, the petals filiform and the lip mostly 4-lobed, pollinia unequal, bird-wing-type. This species has small flowers on an inflorescence with a long thin peduncle, the sepals .2 to .24" [5 to 6 mm] long. It is very similar to E. parviflorum which has smaller leaves, a shorter, thicker peduncle with very similar flowers. Epidendrum poeppigii Hágsater is also similar but has successive flowers, and the leaves about half as wide, the peduncle of the inflorescence thicker and shorter." Hagsater etal 2001
