"Epidendrum hutchisonii belongs to the GROUP Ferryae characterized by the sympodial, caespitose habit, the cane-like stems with numerous leaves, the apical inflorescence subtended by 1 to 2 large spathes, and the nutant, heavy, racemose to paniculate inflorescence with numerous large, fleshy, attractive flowers. The species is recognized by the narrowly lanceolate, acute leaves 3.6 to 7" x .65 to 1.28" [9 to 17.5 x 1.6 to 3.2 cm, the sepals .298 to .32" x .1 to .24" [7.0 to 8.5 x 2.5 to 6.0 mm], elliptic-oblong, abruptly narrowed and acuminate, and the lip .18 to .248" [4.5 to 6.2 x 7.0 to 8.5 mm], bicallose, the calli laminar, crescent shaped, with 1 to 3 low, rounded mid-ribs widening towards the apex. Epidendrum baryanthum Hágsater & Salas Guerr. has a large lip, sub-orbicular in outline, the margins revolute, with the mid-lobe short, wide, and deeply emarginate, thus bi-lobed, formed by two semi-orbicular small lobes, strongly revolute though not evident in natural position, the sepals .48 to .64" [12 to 16 mm] long, and the petals oblanceolate, sub-acute, 2.2-3.0 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 sub-triangular, narrow, the sepals .6 to .72" [15 to 18 mm] long, and the column .4" [10 mm] long. Epidendrum lesteri Hágsater & Dodson has a lip 3-lobed, margin erose-crenate, the lateral lobes subreniform, the mid-lobe rectangular, comparatively large, the apex truncate, somewhat bilobed, short-apiculate, the sepals .64" [16 mm] long, and the 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, the sepals .44 to .48" [11 to 12 mm] long, the petals oblanceolate, narrow, acute, .048" [1.2 mm] wide, and the column arched upwards at the clinandrium-hood."
