Found in central Ecuador on the northern side of Mt Tunguragua on the eastern slope of the Andes at elevations of 1800 to 2200 meters as a giant sized, cool to cold growing epiphyte with simple, cane-like, erect, laterally compressed above stems carrying numerous, all along the stem, alternate, coriaceous, elliptic-lanceolate, acute, narrow, unequally bilobed, margin entire leaves that blooms in the late fall on a terminal, with a prominent, conduplicate, acute spathe, on a mature stem, peduncle enveloped completely by the spathe, laterally compressed, 2.4” [6 cm] long, paniculate, arching, 15.6” [39 cm] long overall, simultaneously about 150 flowered inflorescence with much shorter than the ovary, minute, triangular, acute floral bracts and carrying resupinate yellowish green flowers.

"Epidendrum orthoclinium belongs to the GROUP Ferreyae [See Plate 1572 - 2016] , with simple, cane-like stems, a prominent acute spathe, a paniculate inflorescence, and resupinate flowers; the species is recognized by the short, upright clinandrium, the shallowly three-lobed lip, midlobe cuneate and widened at the apical half to form a spathulate, suborbicular, apiculate plate, and the linear-oblanceolate, acute petals. Epidendrum baezense has narrower leaves, the petals wider and rounded, the midlobe of the lip square and emarginate. Epidendrum excisum Lindl. has oblong, blunt, bilobed leaves, two rounded spathes, the lip deeply three-lobed; it is found at about the same altitude in the area. Epidendrum llaviucoense Hágsater & Dodson, though vegetatively somewhat similar, with larger, obtuse, leaves, has a nodding, racemose inflorescence with two large, non-conduplicate, acute spathes, the floral segments wider, the lip subreniform with a small, bilobed apicallobe."
