"Epidendrum microcarpum is part of the GROUP Macrostachyum SUBGROUP Macrostachyum characterized by the erect, branching, cane-like stems giving rise to an erect to arching, many flowered inflorescence without a spathe the very fleshy lip that is folded and embracing the column and a pubescent to papillose nectary in front of the stigmatic cavity. The species is closely related to E. chondrochilum Schltr., but is recognized by its 9 to 12 simultaneous much smaller flowers, sepals .26" [6.5 mm] long, petals linear and the lip triangular when spread. Epidendrum palaciosii Hágsater & Dodson has many more flowers, with the .28 to .32" [7 to 8 mm] long sepals muriculate outside, and the petals oblanceolate. E. chondrochilum Schltr., has many larger successive flowers. Epidendrum dermatanthum Krzl. has petals nearly as wide as the sepals. Epidendrum oxycalyx Hágsater & Dodson has larger flowers, the sepals 15-23 mm long, acuminate sepals and petals, and a cordiform-triangular lip. Epidendrum pachyneuron Schltr. has .06" [15 mm] long sepals, and short leaves, 1.2 to 1.6" x .4 to .56" [30 to 40 x 10 to 14 mm]. Epidendrum platybracteatum Hágsater, from northwestern Colombia has a compact inflorescence and large, wide floral bracts." Hagsater etal 2001
