Found in Amazonas province of Peru at elevations of 3150 meters as a medium sized, cold growing epiphyte with simple, cane-like, terete, straight stems carrying all along the stem, more than 10, narrowly lanceolate,obtuse, thin, subcoriaceous, apical margin erose leaves that blooms in the fall on a terminal, arising through 1 to 2, prominent, tubular basally, open above, acute spathes, paniculate, bottom 2 branches short, 1.2 to 2.4" [3 to 6 cm] long, arcuate, each branch above compact, central branch 4.8 to 6" [12 to 15 cm] long, rachis terete, naked, 5.6 to 8.8" [14 to 22 cm] long, overall, simultaneously 50 to 70 flowered inflorescence with very short, filiform, floral bracts and carrying resupinate flowers without fragrance or color data.

"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."
