" Epidendrum tolimense 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 tall overall size, the flowers yellow or yellow-green with 4 pollinia, .4 to .44" [10 to 11 mm] long sepals, apiculate, suborbicular to ovate-subcordate lip when spread, and the wide nectary. It is also the only species of this group in Central America. Epidendrum rhodanthum Hágsater & Dodson also has 4 pollinia, is somewhat smaller, sepals being .38" [8.5 mm] long, the flowers white and old rose colored, the lip is proportionately wider, and the nectary narrow. Epidendrum chrysanthum Hágsater & Dodson is smaller still, 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 with a slit along one side. Most species in this group are found in Ecuador and neighboring areas of Colombia and Peru .
