Epidendrum hookerianum belongs to the GROUP Amphyglottis SUBGROUP Glossaspis which is recognized by the caespitose habit, simple stems, leaves oblong-lanceolate, coriaceous, bilobed and elongate peduncle of the erect, racemose inflorescence, the flowers non-resupinate, the callus simple, elongate, fleshy, sulcate towards the base. The species is recognized by the sepals and petals being very narrow, the lateral lobes are semi-ovate, deeply fimbriate towards the apex of the outer margin, and the mid-lobe is linear-lanceolate, the margin sub-dentate and has a mid-rib running down the middle. Epidendrum vinosum Schltr. has pale wine-colored flowers, sepals and petals .68" [17 mm] long, oblong, apex obtuse to sub-truncate, the lip reminiscent of a three-corner hat, the lateral lobes retrorse, and with a large white callus, covering most of the mid-lobe. E blepharoclinium has relatively large flowers, pink-purple flowers (rarely white, as per photograph published by Fiske), with a large complicated white callus; sepals and petals .84 to 1.04" [21 to 26 mm] long, both equally wide, .15" [4 mm]; the mid-lobe rhombic, about as wide as it is long. Epidendrum glossaspis Rchb.f. also has pink purple flowers, with the large, simple, white callus, flowers large, sepals 1.04 to .132" [26 to 33 mm] long, straight, the petals straight, linear-triangular, .04" [1 mm] wide at the base, and the lip formed by 3, sub-parallel lobes, the lateral lobes about half as long as the entire lip, sub-rhombic, acuminate. It very much resembles Epidendrum mainauanum, which is superficially similar, with flowers entirely white, sepals .88" [22 mm] long, and has shorter subquadrate lateral lobes that are only about ¼ the length of the entire lip."
