Flower Size .4" [1 cm]
Found in San Martin department of Peru at elevations around 3200 meters as a small sized, cold growing, caespitose epiphyte with stout, erect ramicauls most likely enveloped by a tubular sheath below the middle 2 to 3 others at the base and carrying a single, coriaceous, elliptical, obtuse, cuneate below into the sessile base leaf that blooms in the winter on an erect, peduncle 4" [10 cm] long, arising through a broad spathe .8" [2 cm] long, rachis 7.6" [18 cm] long, strict, erect, loose, distichous, simultaneously many flowered inflorescence, with the tubular, oblique floral bract longer than the pedicel and carrying flowers without color notes.
"Distinguished by the large, elliptical, sessile leaf far surpassed by a strict, distichous, simultaneous many flowered raceme. The flowers are large and gaping with the sepals long-pubescent within. The petals are narrowly acute and the lip is narrowly obtuse at the apex and unguiculate at the base with erect sides at the middle. Most similar to P scabrata but differs in having sepals pubescent within, entire petals and a lip without calli or basal lobules." Luer 2000
