Found in Pichincha Ecuador at elevations around 2600 meters as a small sized, cold growing epiphyte with ascending, slender ramicauls enveloped 2 ribbed, tubular sheaths with minutely papillose margins and carrying a single, apical, suberect to subpendent, coriaceous, ovate, acute, cuneate below into the petiolate base leaf that blooms in the late summer and early fall on a pendent, sublax, distichous, to 1.6 to 2.4" [4 to 6 cm] long including the broadly flattened, .8" [2 cm] long peduncle, simultaneously several flowered inflorescence near the apex of the ramicaul with broadly ovate, acute floral bracts.

Similar to S piperina but it has elliptical, subacute to obtuse leaves and a concave synsepal that is much deeper than this species which also has erect, oversized dorsal sepals.
