Common Name The Jupiter Pleurothallis [refers to the large flower]

Flower Size .8" [2 cm]

Found in central Ecuador on the western slopes of the Andes at elevations around 2800 to 3300 meters as a miniature to medium sized, cold growing epiphyte or terrestrial on steep banks with slender, sub-erect ramicauls enveloped by a closely adpressed tubular sheath below the middle and 1 to 2 others at the base and carrying a single, apical, more or less spreading, thickly coriaceous, oblong-ovate, sub-acute to obtuse, shortly acuminate, sessile, cordate to deeply cordate base leaf that blooms in the summer and fall on a fascile of .1 to .15" [2 to 4 mm] long, successive, large single flowers arising through a spathe

Similar to P grandiflora but differs in the more robust, thicker leaves, a narrower, multi-veined dorsal sepal, a broad, ciliate-pubescent petals and a verrucose, fringed lip with the sides revolute above the middle and the apex curved as in P deflexa.

CAUTION I am not totally convinced that this is P juptier so please use with caution. Most different from Luer's description is the lip apex that curves down instead of up.
