"Epidendrum dendromacroophorum belongs to the GROUP Pleuranthium , characterized by the caespitose habit, canelike and elongate stems, several short, lateral inflorescences, and the SUBGROUP Dendrobii which has several flowers per raceme, and a short or reduced clinandrium-hood. The species is characterized by the long lateral inflorescences with 4 to 6 flowers helicoidally disposed along the rachis, the very long ovary, 1 to 1.68" [25 to 42 mm] long, cymbiform floral bracts, and the cordiform, apiculate lip. Epidendrum dendrobii Rchb.f. has smaller flowers, and shorter inflorescences and ovaries, a reniform, emarginate lip and oblanceolate petals with the apex rounded. Epidendrum aggregatum Lindl., non Roxb. ex Steud. has sub-sessile inflorescences with small flowers, sepals ca. .28 to .32" [7 to 8 mm] long, and a .24" [6 mm] long ovary. Epidendrum phragmidoides Hágsater, which grows sympatrically in the type locality, has much shorter stems, sub-sessile, single flowered inflorescences, a short .24" [6 mm] ovary thickened along the apical half, tubular, imbricating floral bracts and the lip is somewhat 3-lobed, the base truncate, the clinandrium-hood semi-tubular, much longer than the body of the column."
