"Epidendrum pseudogramineum belongs to the GROUP Macrostachyum SUBGROUP Stenophyton, which is characterized by the branching habit, distichous inflorescence and ovate to cordiform, entire, ecallose lip. This species has been confused with E . gramineum Lindl. = E 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. Epidendrum stenophyton Schltr. is similar in habit, but has larger flowers, the sepals being .28" [7 mm] long."
