"Epidendrum obliquum belongs to the GROUP Andean SUBGROUP Soratae which is characterized by the branching habit starting on a primary stem, infundibuliform, rugose leaf-sheaths, lanceolate, aristate, acute leaves, racemose, subcapitate inflorescence on a short, thin peduncle, and the bicallose lip. The species has a reniform, emarginate lip .184 x .32" [4.6 x 8 mm] in size and a straight column. Epidendrum soratae Rchb.f. is recognlzed by the reniform, apically somewhat 3-lobed lip, and the .24 to .28" [6 to 7 mm] long sepals. Epidendrum cardenasii Hágsater has larger flowers .48 to .52" [12 to 13 mm] long sepals, the lip bilobed, widely emarginate and about as long as it is wide, the base shortly cordate and the calli are laminar and divaricate. Epidendrum bolivianum Schltr. has larger flowers, sepals .52" [13 mm] long, apically bilobed, wider leaves, .28 to .48" [7 to 12 mm] wide, the 3 lobes of the lip about equal in size. Epidendrum tetragonum Hágsater & Dodson has a rectangular, apically truncate lip, sepals .28 to .32" [7 to 8 mm] long, the lip is oblong-rectangular with two inconspicuous lobes at the base. Epidendrum cartlaginiflorum Rchb.f. has a cordiform, somewhat 3-lobed lip, apex obtuse, rounded, and the sepals are .64" [16 mm] long." Hagsater etal 2006
