"Epidendrum davilae belongs to the GROUP Diothonea SUBGROUP Diothonea and subgroup which is characterized by the branching plants, the linear lanceolate to oblong, bilobed leaves, the racemose, arching-nutant inflorescence, membranaceous, rarely fleshy flowers, the entire to 3-lobed, ecallose lip with the margin erose without or with 1-10 thin, smooth to erose keels, the column completely to obliquely united to the lip, and the anther reniform. The new species is recognized by the short, many-flowered inflorescence (up to 20 flowers), sepals dorsally papillose, petals oblong, oblique, the apex obtuse, and the lip united to the basal 2/3 of the column, deeply concave, the base truncate. Epidendrum platystele has fewer flowers, up to 13, sepals dorsally smooth, petals linear-oblong with the apex truncate, and the lip base cuneate. Epidendrum sigmodiothoeum Hágsater & E.Santiago has densely, many flowered inflorescences, but the flowers are small, sepals .22 to .264" [5.5 to 6.6 mm] long, unornamented, the lip is united to the column throughout, the column widely triangular, and the disc of the lip has a pair of very short ribs. Epidendrum gastrochilum Kraenzl. has a laxly few-flowered inflorescence with up to 5 flowers, lateral sepals .56 to .6" [14 to 15 mm] long, unornamented, and the lip entire, ovate-orbicular, the base cuneate and with 6 high laminar ribs on the disc."
