"Epidendrum incomptum belongs to the GROUP Arbuscula SUBGROUP Incomptum, which is characterized by the erect habit with successive lateral growths produced from the middle of the previous growth, few leaves aggregate towards the apex of the stems, roots produced generally only from the base of the primordial stem, inflorescences are short with fleshy yellowish to green to violet-green to black flowers with short ovaries, the lip entire to 3-lobed. The species has a dense inflorescence with up to 20 flowers; lip 3-lobed, ecallose, divaricate lateral lobes with the forward edge usually straight and a sub-quadrate, minutely apiculate mid-lobe. Epidendrum xelidorimarachinii is recognized by the acute sepals, lateral sepals elliptic, dorsal elliptic-lanceolate, petals oblanceolate, 3-veined, lip 3-lobed, slightly convex, margins entire, spreading; lateral lobes .36 to .4" x .34" [9 to 10 x 8.5 mm], semi-obovate, base widely cordate, posterior side semi-obovate, front margin straight; mid-lobe .16 x .32" [4 x 8 mm], deeply bifurcate, formed by a pair of triangular divergent lobes forming a nearly 90° angle, each triangle .16 x .1" [4.0 x 2.5 mm], apex narrowly rounded.
