Part Shade Hot Warm Spring

Common Name The Curled Epidendrum

Flower Size .6 to 7/8" [1.4 to 2.2 cm]

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.

"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 backwadls, 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

NOTE!!! 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.
