"Epidendrum incognitum belongs to the GROUP Saxicola characterized by the pseudobulbous stems, caespitose or scandent habit, the prominent spathaceous bract apically rounded, few-flowered, the erect inflorescence, the flowers purple or yellow, and the surface of the vegetative structures often rugose. The new species is recognized by the reddish brown flowers with the disc yellow, leaves 2.4 to 4.8" [6 to 12 cm] long, petals .52" [13 mm] long, oblanceolate, lip widely cordiform apex truncate, ovary not forming any thickened vesicle, and the yellow column wings nearly parallel to the divaricate calli. It is similar to Epidendrum harmsianum which has sulphuryellow flowers, shorter leaves, 1.4 to 2.4" [3.5 to 6.0 cm] long, petals .64" [14 mm] long, oblanceolate, and lip transversely ovate-oblong. Epidendrum milpoënse Hágsater & E.Santiago has green flowers, petals .64 to .69" [16 to 17.5 mm] long, rhombic-spatulate, lip with 3 parallel ribs on the disc, ovary vesiculate, and column wings short, straight. Epidendrum microcattleyioides D.E.Benn. & Christenson has smaller yellow flowers, petals .44" [11 mm] long, obovate, and the lip reniform, widely emarginate. Epidendrum saxicola Kraenzl. has purple colored flowers, the lip white, petals .6 to .72" [15 to 18 mm] long, oblanceolate, and the lip sub-orbicular and obscurely pentagonal. Epidendrum magnisaxicola Hágsater, Edquén & E.Santiago has large flowers, sepals .96 to 1" [24 to 25 mm] long, pale greenish yellow, the sepals tinged brown, oblanceolate petals 1 x .16" [25 x 4 mm], lip .53 to .44" [13.5 x 11 mm], entire, ovate-rhombic, base truncate, revolute in natural position."
