Found on the Cordillera Oriental in the department of Boyaca Colombia in the edge of fragmented forests at elevations around 2600 meters as a giant sized, cold growing terrestrial with cane-like, simple, terete, thick, straight stems carrying 8 to 15, articulate, all along the upper half of the stem, lanceolate, coriaceous, obtuse, rounded, shortly bilobed, margin entire leaves that blooms in the fall on a few at once from the same cane, terminal, erect, pluri-racemose, peduncle elongate, to [87.5 cm] long, terete, thin, generally enveloped by amplexicaul bracts or enveloped by 5 tubular, acute, scarious bracts, rachis 3.4 to 7.8" [8.5 to 19.5 cm] long, compact, dense, successively 5 to 6, 19 to 45 flowered inflorescence with much shorter than the ovary, triangular, acuminate, gradually shorter towards the apex floral bracts and carrying numerous, non-resupinate, rose-magenta flowers with a pale lilac lip and an orange-yellow throat with the calli and the margin of the clinandrium white.

"Epidendrum susannae belongs to the GROUP Secundum which is recognized by the caespitose habit, numerous coriaceous leaves, and generally an elongate peduncle to a pluri-racemose inflorescence, brightly colored flowers generally pollinated by hummingbirds, and the caudicles of the pollinarium granulose, the tetrads appearing like a loose pile of roof-tiles, without any spathaceous bracts; and SUBGROUP Elongatum, recognized by the non-resupinate flowers with a complicated callus. This species is a terrestrial and has bright purple flowers, the lip pale lilac, with the throat at the base of the lip orange-yellow, and the calli white, formed by two basal, lateral calli, and the main body by a large central entire tubercle, embraced by a pair of shorter lateral tubercles. Epidendrum tricarinatum Rolfe 1917 from Huánuco, Peru, has scarlet flowers with the disc of the lip yellow, sepals .48 to .52" [12 to 13 mm] long, disc with 3 short fleshy keels, the central one longest and the lateral ones with the fleshy lobulated base spread onto the lateral lobes of the lip. Epidendrum arachnoglossum André, a common species around Bogotá, has violet-crimson flowers, a many-lobed white and orange-yellow callus, and the deeply fringed lip forms a nearly entire, orbicular lamina, the base cordate."
