Found in Cajamarca department of Peru at elevations around 2700 meters as a small sized, cold growing, caespitose epiphyte with erect, slender ramicauls enveloped by 3 imbricating, loose, tubular sheaths and carrying a single, apical, erect, coriaceous, oblong-spathulate, narrowing below into the petiolate base leaf that blooms in the fall on an erect, arising through a small spathe, subsecund, flexuous, to 9.2" [23 cm] long, laxly many flowered inflorescence with ovate-lanceolate floral bracts and carrying brown colored flowers.

This species and S cuencana are both said to be synonyms of S tricardium by many authors but Luer keeps them separate. All three are related to S argentata.
