"Epidendrum ornis belongs to the GROUP Arbuscula SUBGROUP Incomptum which is characterized by the erect habit with successive lateral growths produced from the middle of the previous growth, few leaves aggregate towards the apex of the stems, roots generally only from the base of the primordial stem, and with fleshy yellowish to green to violet-green to black flowers with short ovaries, the lip entire to 3- lobed. The species is recognized by the bifoliate stems, leaves ovate-lanceolate, inflorescence with up to 12 ochre-yellow flowers, lateral sepals falcate, .52" [13 mm] long, petals linear-oblanceolate, narrow,.08" [2 mm] wide, and lip clearly 3-lobed, the lateral lobes spreading, obliquely dolabriform, mid-lobe oblong, apically expanded and bilobed. It is reminiscent of Epidendrum tamaënse from the Eastern Andes in Venezuela and neighboring Colombia*, which has 2 to 4 elliptic leaves, up to 17, green to olive-green flowers with purple veins on the lip, lateral sepals oblique, .6 to .84" [15 to 21 mm] long, petals narrowly obtrullate, .28 to .32" [7.0 to 7.8 mm] wide, and the lateral lobes of the lip orbicular. Epidendrum macuchiense Hágsater & E.Santiago, from the western slope of the Andes in Ecuador has 4 lanceolate leaves, green flowers, lateral sepals .4" [10 mm] long, oblique, petals linear-oblanceolate, .04" [1 mm] wide, lip with transversely elliptic to sub-orbicular lateral lobes, and the mid-lobe sub-quadrate-cuneate. Epidendrum boekei Hágsater, from the estern Andes in southern Peru, has narrowly elliptic leaves, 5 to 7, green to greenish yellow flowers, lateral sepals oblique, .48" [12 mm] long, petals oblanceolate, .12 to .24" [3 to 6 mm] wide, and the lateral lobes of the lip obovate, mid-lobe sub-quadrate."
