The species is recognized by the short plants, 28.4" [72 cm] tall including the inflorescence, the petals linear-filiform, the sepals dorsally muricate and reddish purple, ventrally green to greenish brown, .38 to .392" [9.5 to 9.8 mm] long, lateral lobes of the lip rectangular-dolabriform with the lateral margin erose, and the lip with a purple splotch covering the disc including the calli. Epidendrum sodiroi (syn. E. goodspeedianum A.D.Hawkes) has taller plants, 40 to 120" [100 to 300 cm] tall, and the lip only slightly 3-lobed with the margin fimbriate. Epidendrum calothyrsus Schltr. has even taller plants to 160" [400 cm high], the lip immaculate, incipiently 3-lobed with the lateral lobes semi-orbicular-quadrate and the margin denticulate."
