Found in Norte de Santander departments of Colombia in cloud forests at elevations around 2100 meters as a miniature to small sized, cold growing, caespitose epiphyte with slender, erect ramicauls with a tubular sheath below the middle and 2 others at the base and carrying a single, apical, erect to suberect, coriaceous, narrowly linear with revolute sides, acute, shallowly cordate below into the sessile base leaf that blooms in the later spring on a fascile of .08 to .12" [2 to 3 mm] long, concealed within the spathe, successively single flowered inflorescence with infundibular, shorter than the ovary floral bracts.
This species and P subtilis are very similar vegetatively and differ only in the flowers with P calamifolia having thick petals, especially at the obtuse apex and the lip is proportionally larger, non-verrucose and concave at the end unlike P sutilis which has thin, acute petals and the lip is verrucose and not concave but sharply deflexed apically.
