"Epidendrum sucumbiense belongs to the GROUP Pseudepidendrum SUBGROUP Paniculatum , recognized by the caespitose habit, cane-like stems, paniculate inflorescence, filiform petals, four-lobed lip and bird-wing type pollinia. This species has green and white colored 4 simultaneous flowers, with two prominent, triangular, laminar calli, and 6.3-6.8 mm long sepalsIt is similar to Epidendrum parviflorum whose sepals are smaller, .16 to .2" [4 to 5 mm] long. Epidendrum poeppigii Hágsater has longer leaves, 3.6 to 6.8" [9 to 17 cm] long. Epidendrum agoyanense Hágsater & Dodson has a somewhat similar habit, but leaves are wider, 1 to 1.4" [2.5 to 3.5 cm] wide, flowers are larger with sepals .36 to .44" [9 to 11 mm] long and the apical lobes much reduced. Epidendrum yungasense Rolfe has flowers about the same size but much thinner, the column slender, and the lip is spotted with purple." Hagsater etal 2001
