Flower Size 1" [2.5 cm]

Found in Costa Rica, Panama and Colombia as a miniature sized, hot to warm growing epiphytic herb at elevations of sealevel to 1000 meters with close set, ovoid, smooth psuedobulbs carrying a single, apical, erect, coriaceous, elliptic, obtuse, basally clasping leaf that blooms in the later spring through summer and is different in that it has a basal, 2" [5 cm] long, few flowered, erect to lateral inflorescences with fragrant flowers .

Said to be a synonym of E laterale and seems to be very similar but differs in the non pinched opening at the lip base and column foot, if it is a synonym then E laterale takes precedence.
