"Epidendrum chinchaoënse belongs to the GROUP Elleanthoides SUBGROUP Rhombochilum recognized by the branching habit, small fleshy leaves and a short 3 to 4 flowered, nutant inflorescence on a short thick peduncle. The species is recognized by the long, coriaceous leaves to 2.24" [5.6 cm] long, relatively small flowers, lateral sepals .32" [8 mm] long, falcate, acuminate, and the linear-filiform petals. Epidendrum tolimense Lindl. has shorter, ovate-lanceolate leaves to 1.48" [3.7 cm] long, .4 to .44" [10 to 11 mm] long sepals, apiculate, sub-orbicular to ovate-sub-cordate lip when spread, and the wide nectary. Epidendrum rhodanthum Hágsater & Dodson also has 4 pollinia, the flowers white and old rose colored, the lip is proportionately wider, and the nectary narrow. Epidendrum chrysanthum Hágsater & Dodson has smaller flowers, sepals being about .18" [4.5 mm] long, and only has 2 pollinia. Epidendrum rhombochilum L.O.Williams has .28 to .32" [7 to 8 mm] long sepals, also has two pollinia, each with a slit along one side. Most species in this group are found in Ecuador and neighboring areas of Colombia and Peru. Epidendrum guacamayense Hágsater & Dodson belongs to the SUBGROUP Guacamayense with branching inflorescences with long, hair-thin peduncles." Hagsater etal 2009
