"Epidendrum flexuoecallosum belongs to the GROUP Lanium which is characterized by rhizomatous plants, the stems cane-like to pseudobublous, leaves generally aggregate towards the apex, flowers non-resupinate, more or less pubescent, pollinia 2 or 4. The species is recognized by the 1 to 2,6" [2.5 to 6.5 cm] long stems with 3 to 6 leaves distributed throughout, the leaves elliptic-lanceolate, acute, a paniculate inflorescence with the peduncle and rachis nearly straight, spreading, linear petals with the margin densely ciliate, and an ecallose lip, with two short cunicula at the base of the blade.
