"Epidendrum baryanthum belongs to the GROUP Ferreyae which is characterized by the sympodial, caespitose habit, canelike stems with numerous leaves, apical inflorescence subtended by 1 to 2 large spathes, and a nutant, heavy racemose to paniculate inflorescence with numerous large, fleshy, attractive flowers. The new species is recognized by the large sub-orbicular lip in outline, the margins revolute, with the mid-lobe short, wide and deeply emarginate, thus bi-lobed, formed by two semicircular small lobes strongly revolute, not evident in natural position; sepals .48 to . 64" [12 to 16 mm] long, petals are oblanceolate, sub-acute, .088 to -12" [2.2to 3.0 mm] wide. It is similar to Epidendrum ferreyrae Hágsater & Ric.Fernández, which has a clearly 3-lobed lip with the lateral lobes dolabriform and the mid-lobe subtriangular, narrow; sepals .6 to .72" [15 to 18 mm] long, column .4" [10 mm] long. Epidendrum lesteri Hágsater & Dodson has 3-lobed, margin erose-crenate; lateral lobes sub-reniform; mid-lobe rectangular, comparatively large, the apex truncate, somewhat bilobed, short-apiculate; sepals .64" [16 mm] long, petals oblanceolate, apically rounded, .08" [2 mm] wide. Epidendrum orthoclinium Hágsater & Dodson, has a 3-lobed lip, the lateral lobes semi-circular, margin dentate, mid-lobe spatulate; sepals .44 to .48" [11 to 12 mm] long, petals oblanceolate, narrow, acute, .048" [1.2 mm] wide, column arched upwards at the clinandrium."
