Found in Costa Rica and Panama at elevations around 1500 to 2200 meters as a small sized, cool to cold, shortly repent to caespitose growing epiphyte with stout, erect ramcauls enveloped by 6 to 8, loose, tubular sheaths and carrying a single, apical, erect, thickly coriaceous, narrowly elliptical to narrowly ovate, acute, cuneate below into the conduplicate, sessile base leaf that blooms in the late fall and winter on a fascile of pubescent, arising through a spathe at the apex of the ramicaul, .8 to 1.6" [2 to 4 cm] long, successively single, few flowered inflorescence with inflated, shorter than the ovary floral bracts and carrying cleistogamous flowers that never open.
"A few flowers are borne simultaneously in a fascile from the deep cleft of the conduplicate base of the lead. Similar to Echinosepala aspasicensis and Echinosepala uncinata but the lip differs in the acute apex with incurved sides and in the broad, transvbersely rugose callus that occupies most of the disc."
