Found in El Oro province of Ecuador in forests at elevations around 1800 meters as a small sized, cool growing caespitose epiphyte with slender, erect ramicauls enveloped by a close tubular sheath on the lower third and 2 others at the base and carrying a single, apical, erect, coriaceous, narrowly ovate, acute, acuminate, rounded to subcordate below into the sesille base leaf that blooms in the spring and summer on a fascile, arising and enveloped by a spathe of .12 to .2" [3 to 5 mm] long, successively single, few flowered inflorescence with thin, tubular floral bract.
Similar to P ruberrima vegetatively but instead of narrower, the narrowly ovate, seven veined dorsal sepal is about as wide as the synsepal. Instead of broadly concave, the narrowly ovate synsepal is slightly convex with lightly recurved sides. The papillose lip is ovate, obtuse and longer than broad and the conspicuous central callus seen in P ruberrima is absent. P persimilis is superficially similar is found in the same locality. It has a shorter peduncle, a three veined dorsal sepal and a proportionally longer lip ." Luer 2005
