Found in Antioquia department of Colombia on the northern slope of the Cordillera Central at elevations of 200 to 800 meters as a medium sized, hot to warm growing epiphyte with simple, cane-like, basally terete, laterally compressed above stems carrying 10, all along the stem, alternate, articulate, suberect, elliptic, acuminate, margin entire leaves that blooms on a terminal, erect, racmose at first flowering, new racemes produced successively from the old, distichous, peduncle to 8" [20 cm] long, laterally compressed, enveloped completely by tubular, scarious sheaths, rachis 2" [5 cm] long, to 10" [25 cm] long overall, successively single, few flowered inflorescence with nearly as long as the ovary, elliptic, conduplicate, subacute, imbricating, persistent on rachis after flowering floral bracts and carrying resupinate, creamy yellow flowers with the apex tinged pink.

"Epidendrum corymborkiphyllum belongs to the GROUP Alberti which is characterized by the sympodial habit, laterally compressed to ancipitose or somewhat fusiform-thickened stems, inflorescence apical or apical and lateral racemose, with distichous, more or less imbricating bracts on peduncle, producing one flower at a time, and the SUBGROUP Allenii which is characterized by stems with numerous leaves, apical inflorescence (rarely lateral), peduncle elongate, bare, non-bract bearing, two-winged, rachis short, covered by rounded, usually imbricating, bracts. The species is recognized by the creamy yellow flowers, apex tinged pink, sepals oblong apex rounded, .54 to .56" [13.5 to 14 mm] long, petals obtrullate, margin entire, lip cordiform with a pair of small sub-spherical calli. Epidendrum tropidioides Garay has green flowers, sepals narrowly lanceolate, apex acute, .88 to 1,04" [22 to 26 mm] long, petals narrowly rhombic, margin erose, lip obovate, base cuneate, with a pair of prominent, laminar calli. Epidendrum lagenomorphum Hágsater & Dodson has green flowers, sepals .5 to .516" [12.5 to 12.9 mm] long, petals narrowly oblanceolate, lip sub-orbicular, base cuneate. Epidendrum adnatum Ames & C.Schweinf. has green flowers, sepals hyaline, tinged with purple, sepals .36 to .48" [9 to 12 mm] long, oblanceolate, apex acute, petals linear-filiform, lip ovate, apex acute, and a pair of prominent calli. Epidendrum gentry Dodson shares the size of the flowers, obtrullate petals, and the prominent clinandrium-hood, but the lip is wide-ovate somewhat rhombic, base cuneate, and that species has the stems somewhat fusiform-thickened in the middle, and leaves distributed only along the apical half of the stem."
