Found in Vaupes department of Colombia in forests at elevations around 100 meters as a small sized, hot growing terrestrial with erect, cane-like stems carrying towards the apex, plicate, oblong-elliptic, acuminate, delicate, with 7 prominent nerves, petiolate base leaves that blooms in the fall on a terminal, raceme to 4” [10 cm] long, rachis 1.6 to 2” [4 to 5 cm] long, pubescent, densely many-flowered inflorescence, with ovate-lanceolate, acute, pubescent on both surfaces, longer than the ovary floral bracts and carrying white flowers with a red gymnostemium.

"This species appears to be related to P. guianensis (Schltr.) C. Schweinf. & Correll, but its hypochile is obtriangular, with a basal, oblong, pubescent callus and two prominent lamellae running to the base of epichile. The hypochile of P. guianensis is round-obovate in outline. The basal section of the lip is ventrally pubescent either side of the axis and the margins lightly ciliate; the middle nerve ventrally is gently sulcate for most of its length, dorsally quite strongly sulcate for the full length; lateral lobes obtuse to rounded" Szlach. & Baranow 2013
