"Epidendrum stenophyton Schltr. belongs to the GROUP Macrostachyum SUBGROUP Stenophyton, which is characterized by tlie branching habit, distichous inflorescence and ovate to cordiform, entire, ecallose lip. The species is recognized by the branching inflorescence, larger flowers than Epidendrum pseudogramineum, the sepals being .28" [7 mm] long. than Epidendrum pseudogramineumis similar in habit and has very small flowers, and a branching inflorescence. All other species of this group have much larger flowers. This species has been confused with Epidendrum parviflorum , which, however, has wider narrowly elliptic leaves .32" [8 mm] wide, a carinate, callose lip and much narrower, filiform petals. Epidendrum dendrobioides Thunb. has larger flowers and a racemose inflorescence." Adapted from E pseudogramineum Icones 8 Plate 875 Hagsater etal 2006
