Found in Tungurahua and Napo provinces of Ecuador on the eastern slopes of the Andes in very wet montane forest along rivers at elevations of 600 to 2400 meters as a miniature sized, warm to cold, pendant growing epiphyte with laterally compressed stems arising from near the middle to near the apex of the previous mature stem and completely enveloped by imbricating, evanescent leaf-bearing sheaths and carrying articulate, narrowly lanceolate, acuminate, succulent leaves that blooms in the late spring and early summer on a terminal, peduncle provided with a bract intermediate in size and shape between the leaves and the floral bracts, racemose, sucessively single, 6 to 7 flowered inflorescence triangular, acuminate, dorsally carinate, progressively smaller floral bracts and carrying resupinate, clear green flowers with the lip and the apex of the column white.

"Epidendrum nanosimplex belongs to GROUP Nanum SUBGROUP Nanoecallosum characterized by the dichaea-like pendant stems with pairs of apposing flowers on an inflorescence without spathaceous bracts and has prominent floral bracts and a simple, entire lip. The species can be recognized by the simple, entire lip, the vesicle of the ovary occupying about 1/3 of the ovary, and the entire clinandrium which slightly covers the anther. Epidendrum dichaeoides Carnevali & G. Romero has 1 to 2 flowers, but longer .24 to .36" [6 to 9 mm] sepals, and wider petals .08 to .082" [2 to 2.5 mm] clearly distinguish it. Other species in this group have a 3-lobed lip." Hagsater etal 1999
