Flower Size .2" [5mm]

Found in Napo province of Ecuador at elevations around 1850 meters as a small to medium sized, cool growing, caespitose epiphyte with erect, stout ramicauls enveloped by a close, tubular sheath below the middle and 2 to 3 others at the base and carrying a single, apical, erect, coriaceous, narrowly elliptical, acute, narrowly cuneate below into the sessile base leaf that blooms in the summer on a fascile of 1 to 2, arising through a fugaceous spathe, .4" [1 cm] long, 1 to loosely 2 flowered, racemose inflorescence with an infundibular, shorter to as long as the pedicel floral bract.

Characterized by the long, stout ramicaul, narrowly elliptical, acute leaf that blooms at the base of the leaf on a fascile of old inflorescence from which the single flower often followed by a second ona very short raceme. The flower is pendent and resupinate. The synsepal is cucullate above the middle sepal and parellel petals. The lip is suborbicular with the basal lobes surrounding the column, A pair of hor-like calli protrude from the disc at the base. Similar to P hartwegii but this one differs with longer and more slender calli and the apex of the lip is rounded." Luer 1999
