Found in Peru at elevations around 2200 meters as a small to large sized, cold growing terrestrial in wet montane cloud forests with branching towards the apex of the mature, erect, cane-like, terete, somewhat flexuous stem with the branches shorter than the main stem and carrying numerous on the main stem, 11 to 18 on each branch, distributed throughout, alternate, distichous, coriaceous, rugose on the dorsal surface, ovate, small, subacute, prominent dorsal keel, slightly undulate margin leaves that blooms in the winter and spring on a terminal, without a spathe, occuring only once, peduncle very short, terete, thin, naked, racemose, distichous, erect, 2 to 2.4" [5 to 6 cm] long, strongly flexuous rhachis, 1.2 to 2" [3 to 5 cm] long, successively 2 to 4, 4 to 9 flowered inflorescence with longer than the ovary, smaller towards the apex, narrowly triangular, acute, crenulate and entire margin, retrose, clasping, strongly striate ventrally, floral bracts and carrying non-resupinate flowers without fragrance data.

"Epidendrum stenocalymmum belongs to the GROUP Aquaticum characterized by the branching habit, distichous inflorescence, fleshy flowers and pubescent nectaries. The new species is recognized by the small, ovate leaves, simple, erect raceme, entire, oblanceolate, unguiculate petals and the cuneate lip forming a deep sac in front of the column, so that the column is not visible. It resembles E. lindae Hágsater & Dodson which has larger, wider leaves, a branching rachis, linear petals and a terete ovary, the lip is only slightly cuneate but 3-lobed, with the lateral lobes subquadrate. Epidendrum campylorhachis Hágsater has a three-lobed lip wlth the base cuneate, narrowly oblanceolate petals and an oblique, deeply triquetrous ovary, in addition, the rachis segments are prominently incurved below each bract. The new species has reen confused with Epidendrum alsum, a Venezuelan species with larger habit and leaves, a paniculate inflorescence and somewhat 3-lobed lip, the basal lobes broadly rounded, the petals elliptic. Epidendrum bractiacuminatum Hágsater & Dodson also has a distichous inflorescence, but is much larger overall, leaves 5.2 to 7.2" [13 to 18 cm] long, floral bracts .6 to 1.6" [15-45 mm] long, sepals .48 to .68" [12 to 17 mm] long, and the lip is cordiform."
