Flower Size .08 " [2 mm]

Found in the Darien of Panama at elevations of 750 to 1400 meters as a miniature to small sized, warm growing epiphyte with slender, erect ramicauls with a tightly adpressed, tubular sheath below the middle and 2 to 3 others at the base and carrying a single, erect, coriaceous, ovate, acute, rounded below into the sessile base leaf that blooms in the later summer on erect, arising through a spathe at the base of the leaf, a fascile of successively single, few, filiform, 1.6 to 2" [4 to 5 cm] long including the 1 to 1.2" [2.5 to 3 cm] long, successively single, 2 to 3 [7] flowered inflorescence and has an infundibular, as long as the pedicel floral bract.

"Characterized by a few distantly flowered and successively two flowered racemes borne in a fascile, about half as long as the leaf. The bilabiate flowers, are most similar to P volcanica from Panama. The spotted sepals of P dukei are broader, three veined instead of single veined and the margins are serrulate. The three lobed lip is very similar with the acute anterior lobe and erct, roudnded basal lobes flanking the column." Luer 1998
