Found in Colombia, Ecuador and Bolivia at elevations around 1800 to 3000 meters as a small to medium sized, cool to cold growing, densely caespitose epiphyte with slender, erect, fasciculate ramicauls enveloped by a tubular sheath near the middle and 2 to 3, imbricating sheaths at the base at the base and carrying a single, apical, erect, coriaceous, elliptical-oblong, obtuse, cuneate below into the petiolate base leaf that blooms in the fall on 2 to 3, slender, arising through a slender spathe from an annulus just below the abscission layer, congested, more or less distichous, on a 6 to 10" [15 to 25 cm] long including the 1.2" [3 cm] long peduncle, simultaneously many flowered inflorescence with an infundibular, as long to shorter than the ovary floral bract.

Similar to P velaticaulis, the flowers differing mostly in details of the lip. L rhodotantha has an oblong lip with a pair of erect, central calli. The basal cavity is narrow and transverse. The lip of P velaticalis is ovate with intramarginal calli and the basal cavity is more or less rounded." Luer 1998
