Found in Imbabura and Napo provinces of Ecuador at elevations of 3200 to 3700 meters as a medium sized, cold growing, caespitose epiphyte with slender, erect ramicauls enveloped by a long tubular sheath below the middle and 2 to 3 shorter ones at the base and carrying a single, apical, coriaceous, deflexed, cordate-ovate, acute, more or less concave below into the deeply cordate, sessile base leaf that blooms in the summer and fall on a reclining to suberect, arising through a conduplicate spathe, a fascile of short, successively single flowered inflorescence with thin, as long as to less than half the pedicel floral bracts.

Part of the Pleurothallis cardiostola/Pleurothallis lilijae complex. Distinguished by the relatively large, yellow flower with the dorsal sepals nearly glabrou and only three veined, relatively narrow, widely expanded petals and a more or less flat, triangular lip that is only slightly channeled medially."
