The species is recognized by the narrowly lanceolate leaves 2 to 5.6" x .52 to .96" [5 to 14 x 1.3 to 2.4 cm], short inflorescence 2 to 5.6" [5 to 14 cm] long with the rachis straight to slightly flexuous, basically distichous, the flowers secund, the 6 to 15 flowers generally greenish purple or greenish yellow, with the lip sometimes reddish towards the base, large lateral sepals .64 to 32" x .72 to .32" [16 to 18 x 6 to 8 mm], the apex of the floral segments acuminate, petals linear, single veined, oblique, and the lip narrowly triangular with the base cordate.

Epidendrum rostrigerum Rchb.f. has oblong elliptic leaves 1.6 to 3.6 x .8 to 1.2" [4 to 9 x 2 to 3 cm], the inflorescence with a straight rachis has up to 22 flowers similar in color but smaller, sepals .36 to .44" [9 to 1 mm] long, the apex of the anther surpassing the apex of the column, and the lip lunate, nearly semi-orbicular. Epidendrum macrostachyum Lindl. has elongate, pyramidal inflorescences ca. 6.4 to 12" [16 to 30 cm] long, flower the color of ripe olives, black-brown, sepals .44 to .46" x .2 to .24" 11.0-11.5 x 5-6 mm, the apices of the floral segments obtuse, petals oblong, and the lip widely cordiform."
