Found in Costa Rica, Panama and Colombia at elevations around 300 to 1000 meters as a medium to large sized, hot to warm growing epiphyte with terete at the base, compressed above stems enveloped in youth by amply loose, appressed sheaths and carrying 2 to 3, approximate, jointed, oblong to elliptic-oblong, coriaceous, bilobed apically, obliquely ascending leaves that blooms in the spring on a terminal, complanate, alate, to 9.2" [to 23 cm] long, to 13 flowered inflorescence subtended by conduplicate sheaths with decurrent keels.

"Epidendrum circinatum belongs to lhe GROUP Spathiger characterized by the sympodial habit, coriaceous leaves, racemose, distichous inflorescence and fleshy green to purplish f1owers, and the SUBGROUP Circinatum which has large, secund f1owers. The species is recognized by the large plants, its broadly laterally compressed stems, the wide, elliptic to obovate-elliptic, rounded, emarginate leaves, successive, non-resupinate f1owers, the sepals and petals strongly coiled backwards, and the paniculate, obovate to obscurely 3-lobed lip inflexed at an angle of 90° with respect to the axis of the column. It is similar to E. vexillium Hágsater, which has spreading sepals and petals, and a subrectangular to suborbicular lip, wider towards the base. Epidendrum galeochilum Hágsater is vegetatively similar but has a c1eeply concave lip, reminiscent of a pipe." Hagsater etal

CAUTION !!! the reference below of Misas 2006 puting this species in Colombia is incorrect, please continue to E vexillium which is the correct species for the Colombian citations.
