The species is recognized by the intermediate size of the plants, about 20" [50 cm] tall, narrowly elliptic and short acuminate leaves, racemose inflorescence, the greenish copper sepals .6" [15 mm] long and petals, column base greenish, apical half lavender, the lip hyaline white, the calli and ribs lavender, surrounded by a darker ring, the convex lip with the lateral lobes hemi-elliptic. Epidendrum rodrigoi Hágsater endemic to Colombia, has elliptic-lanceolate leaves, 7 simultaneous, green flowers, the clearly 3-lobed lip pink, the lateral lobes dolabriform.

Epidendrum paniculatum Ruiz & Pavón has a paniculate inflorescence with green flowers, the apex of the column and lip white, the disk with numerous dark red markings, sepals .48 to 52" [12 to 13 mm] long."
