"Epidendrum notostachyum belongs to the GROUP Macrostachyum , which is characterized by the monopodial plants with sub-apical branching, rugose leaf sheaths, large leaves generally spreading, racemose, erect inflorescence, and fleshy flowers generally green to black (ripe olive colored), as well as yellow to pink to purple, with an entire, conduplicate, generally ecallose lip embracing the column, and the nectary pubescent to papillose in front of the stigmatic cavity and at least at the base of the lip. The species is recognized by the narrow, lanceolate leaves, 4.5-15 x 0.8-2.2 cm, floral bracts small; flowers green or greenish white, sepals dorsally papillose, anther ovoid with the apex truncate; nectary shallow, penetrating about 2/3 of the column, not the ovary. Epidendrum borealistachyum Hágsater & E.Santiago is vegetatively very similar, but the flowers lilac-white, apex of the column deep purple, nectary deep, penetrating 1/3 of the ovary.

Epidendrum chondrochilum Schltr.has wider leaves, .56 to 1.4" [1.4 to 3.5 cm] wide; floral bracts are prominent, triangular-ovate, .32 to .72" [8 TO 18 mm] long, flowers are black-brown, the color of ripe olives, sepals are dorsally glabrous. Epidendrum microrigidiflorum Hágsater has ovate-lanceolate leaves, apex acuminate, flowers are greenish yellow to cream-colored, sepals dorsally glabrous, and the lip is widely rhombic, with the base cuneate."
