"Epidendrum nasturtichilum belongs to the GROUP Nanum , which is characterized by the Dichaea-like horizontal or pendulous stems, the inflorescence produced by pairs of opposite flowers without spathes, but with prominent floral bracts. The new species is recognized by the pale green flowers, sepals .36 to .38" [9.0-9.5 mm] long, petals .308" x .24" [7.7 x 0.6 mm], linear, falcate, the shallowly 3-lobed lip, which is overall somewhat peltate with a triangular mid-lobe with lateral lobes hemi-elliptic, having 3 radiating, arched, thickened veins on each lip lobe with an undulate margin, extended at the apex of each vein, and the ovary ventrally inflated along the apical ¾. Epidendrum nanosimplex has green flowers but the lip and apex of the column white, sepals .16 to .24" [4.0 to 6.0 mm] long, petals .14 to .176 x .04" [3.5 to 4.5 x 1.0 mm], narrowly oblanceolate, lip entire without thickened veins and an entire margin, ovary with a short, thickened vesicle. Epidendrum nanum C.Schweinf. has sepals .38 to .44" [9.5 to 11 mm] long, petals .368 x .04" [9.1 x 1.0 mm], linear, a lip clearly 3-lobed, the lateral lobes semi-ovate with the margin entire. Epidendrum integrinanum Hágsater is vegetatively similar but has 6 to 8 flowers, sepals .372 to .384" [9.3 to 9.6 mm] long, petals .36 x .024" [9.0 x 0.6 mm], oblique but not falcate, and a sub-entire lip, longer than wide, margin entire, lateral lobes much reduced."
