"Epidendrum massif-hottense belongs to the GROUP Physinga which is characterized by to the generally small, caespitose plants, the inflorescence apical and racemose producing new racemes with time and thus pluri-racemose, the successive flowers opening one at a time on an elongate peduncle with acuminate bracts, the lip entire and the ovary with a prominent vesicle. The species is recognized by leaves 1.23 to 2" x .16 to .24" [3.3 to 5.0 x 0.4 to 0.6 cm], very short bracts on the peduncle of the inflorescence, .08 to .12" [2 to 3 mm] long, much shorter than the internodes, and lip .176 x .268" [4.4 x 6.7 mm], reniform, base slightly cordate. Epidendrum polygonatum has 5 to 12 leaved stem, leaves shorter, 1.12 to 1.56" x .16 to .28" [2.8 to 3.9 x 0.4 to 0.7 cm], ovate-lanceolate, acuminate, and the zig-zag inflorescence, with the bracts of the peduncle .2 to .44" [5 to 11 mm] long, surpassing the internodes, sepals small, .6 to .2" [4 to 5 mm] long, translucent pink, lip .2 x .48" [5 x 12 mm], widely triangular-obcordiform, twice as wide as it is long. Epidendrum ceticaudatum Rinc.-González, Villanueva & E.Santiago, has arching stems 6 to 7.2" [15 to 18 cm] long, 4 leaves distributed along the apical half of stem, flowers larger, sepals .52 to .56" [13 to 14 mm] long, and lip .248 x .384" [6.2 x 9.6 mm], bell-shaped when spread. Epidendrum physodes Rchb.f. has leaves 1.4 to 2.8" x .24 to .48" [3.5 to 7 x 0.6 to 1.2 cm], flowers small, sepals .2 to .32" [5 to 8 mm] long, lip .12 to .2" x .16 to .28" [3 to 5 x 4 to 7 mm] transversely obovate."
