"Epidendrum macuchiense belongs to GROUP Arbuscula SUBGROUP Incomptum which is characterized by the successive lateral growths produced from the middle of the previous growth, few leaves aggregate towards the apex of the stems, a short apical inflorescence with fleshy greenish to violet-green flowers with short ovaries, the lip entire to 3-lobed. The species is recognized by the green flowers, the deeply 3-lobed lip, twice as wide as it is long, .346 x .66" [8.6 x 16.1 mm], the lateral lobes semi-orbicular, and the quadrate-cuneate, emarginate mid-lobe, and the thin, linear-oblanceolate petals .43 x .04" [10.8 x 1 mm]. It resembles Epidendrum homoion Hágsater & Dodson, has a very similar shaped lip .56 to .64" x 1.04 to 1.12" [14 to 16 x 26 to 28 mm], but has obtrullate petals which are much wider .34 x ,24 to .26" [8.5 x 6.0 to 6.5 mm]; the sepals and petals are green and the lip olive-green to purplish green. Epidendrum boekei Hágsater also has a 3-lobed lip, but it is nearly as long as it is wide, .44 to .56 x .56 to .72" [11 to 14 x 14 to 18 mm], the lateral lobes are slightly retrorse, petals narrowly oblanceolate, apex rounded .46 x .12 to .24" [11.5 x 3 to 6 mm], and the calli are narrower and divergent. Epidendrum oenochromum Hágsater & Dodson has burgundy-red colored flowers, the lip is proportionately wider than long, .4 x .56" [10 x 16 mm], but the lateral lobes are orbicular, and petals oblong, .468 x .088" [11.7 x 2.2 mm]."
