Found from Santander, Cundinamarca, Huila and Nariño departments of Colombia, Carchi, Pichincha, Pastaza, Tungurahua, Chimborazo, Morona-Santiago and El Oro provinces of Ecuador, Huanuco, Junin, Amazonas amd Cusco departments of Peru, La Paz department of Bolivia and Merida state of Venezuela in wet montane forests or cloud forests at altitudes of 750 to 2800 meters as a caespitose, small to medium sized, warm to cold growing terrestrial or epiphytic, caespitose species with a long, thin ramicauls enveloped basally by 2 long, close, tubular, distant sheaths and carrying a single, apical, erect, lanceolate, cordate, acute, abruptly narrowing below, prominent midvein, clear green leaf that blooms in the spring and summer on an apical, short, fasciculate, pendulous, successively single, few flowered inflorescence with a small scarious spathe with the flower held dangling from near the leaf base.
The hanging flowers of this species can be quite variable in coloration and form.
"Long ramicauls bear erect, long, narrow leaves. Single large flowers are produced successively, or a few simultaneously, by long, flexible, drooping peduncles, dangling the flowers over the sides of the leaf. The dorsal sepal is multiveined, but the number of veins is inconstant and the sides of the sepals are usually recurved. The petals are acute and much shorter, either 1 or 3 veined with a lobule at the base. The obtuse lip is proportionally small and the disc varies from being merely slightly convex to thickly callous, sometimes even with an erect, conical callus." Luer 2005
Similar to P zarumae but it has a wider dorsal sepal that is about as wide as the synsepal.
