Found in Colombia in the department of Antioquia on the summit of the cordillera Occidental and the department of Valle de Cauca to the south in disturbed cloud forests at elevations of 1750 to 2050 meters as a small sized, cool growing terrestrial with terete, thin, branching sub apically, erect, straight stems carrying 5 to 8, all along the stem, unequal, basal and apical leaves smaller, middle leaves largest, oblong-elliptic, rounded apically, minutely apiculate, entire margined leaves that blooms in the earlier winter through later spring on a terminal, racemose peduncle to .08 to .12" [2 to 3 mm] long, laterally compressed, rachis .38 to .4" [.9 to 1 cm] long, laterally compressed, .48" [1.3 cm] long overall, successively 4 flowered inflorescence with much shorter than the ovary, widely triangular, acute, embracing floral bracts and carrying non-resupinate green flowers.

"Epidendrum betancurii belongs to the GROUP Batesii, which is characterized by the monopodial main stem with a subapical branching habit, acute leaves, successive, essentially non-resupinate flowers, opening one at a time, deep nectary, entire to 3-lobed lip with the lateral lobes more or less fimbriate to erose. The species is recognized by the comparatively wide leaves ca. 2:1 (length:width), oblong-elliptic, the margin entire, inflorescence .48" [1.2 cm] long with 4, successive, green flowers, sepals .6" [15 mm] long, narrowly obovate, petals .52" [14 mm] long, spatulate, the lateral lobes of the lip dolabriform, the margin erose, and the mid-lobe oblong with the apical half deeply bilobed, mucronate in the sinus. Epidendrum batesii Dodson has proportionately narrower leaves, length:width = 4:1, 1 to 1.36" x .24 to .32" [2.5 to 3.4 x 0.6 to 0.8 cm], narrower petals, .68 to .76" [1.7 to 1.9 mm] wide, mid-lobe of the lip shorter, and entire, .091 to .1" [2.3 to 2.5 mm] long. Epidendrum acrobatesii Hágsater & Dodson, endemic to southern Ecuador has leaves ca. 3:1, elliptic, with the margin minutely erose-dentate, inflorescence 2" [5 cm] long, with 6 to 12 greenish yellow flowers, sepals .4 to .48" [10 to 12 mm] long, petals linear, lateral lobes of the lip nearly as long as the mid-lobe, which is apically truncate. Epidendrum farallonense Hágsater has leaves ca. 3:1, lanceolate elliptic, the margin minutely erose-dentate, the inflorescence has 3 to 9 flowers, sepals.28 to .34" [7.0 to 8.5 mm] long, petals narrowly oblanceolate .26 to .3" [6.5 to 7.5 mm] long, and the lateral lobes of the lip are dolabriform with the margin lacerate-dentate and the mid-lobe sub-rectangular, the apex emarginate."
