Stelis piestopus Schltr. 1921 SECTION Stelis Drawing by © Carl Luer and The Swiss Orchid Foundation at the Jany Renz Herbaria Website

Common Name The ? Stelis [refers to the flowers]

Flower Size .12" [3 mm]

Found in Cajamarca Peru at elevations around 2700 meters as a small sized, cold growing 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, subsecund, flexuous, to 9.2" [23 cm] long, laxly many flowered inflorescence arising through a small spathe with ovate-lanceolate floral bracts.

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.
