The species is recognized by its thin, delicate stems borne singly from near the top of the previous one, the nodding, 2 to 3 flowered raceme, flowers pale green, the apex of the column reddish, the ovary thin, petals narrowly oblanceolate, 1-veined, the lateral lobes suborbicular and the trapezoidal midlobe deeply emarginate, mucronate. Epidendrum karstenii has still smaller flowers, the sepals .24" [6 mm] long, and a cylindrical inflorescence with numerous simultaneous flowers." Hagsater etal 1999
