"Epidendrum campylostele belongs to the GROUP Elleanthoides SUBGROUP Guacamayense, characterized by the thin, branching stems, long, linear, grassy leaves, filiform peduncle and rachis of the inflorescence. The new species is recognized by the relatively intermediate flowers for the group: sepals .24 to .036" [6 to .9 mm] long, the incurved column arching upwards, and the falcate lateral sepals. Epidendrum elleanthoides has smaller flowers, the sepals .148 to .44" [3.7 to 4.4 mm] long, lip transversely ovate, and bicarinate callus.Epidendrum guacamayense Hágsater & Dodson , has the inflorescence 1.4 to 5.2" [3.5 to 13 cm] long, rachis zig-zag, sepals -28 to .3" [7.0 to 7.5 mm] long, the ecallose lip completely embracing and covering the column. Epidendrum montispichinchense Hágsater & Dodson has a short, thick, straight column, forming a wide cavity with the lip, sepals are .256 to .276" [6.4 to 6.8 mm] long, the apical margin of the leaves is entire. Epidendrum elleanthodiceras Hágsater & E. Santiago has larger flowers with sepals .4" [10 mm] long, acute teeth at the apex of the long, thin, arched, column, unlike any oiher species of the group, and a triangular lip; Epidendrum hesperium Hágsater & E. Santiago has a generally simple, racemose inflorescence witn up to 15 flowers, shorter sepals and does not form a foot-like bud with a prominent heel." Hagsater etal 2004
