Common Name The Smooth Pleurothallis [refers to the spathe]

Flower Size .2" [5 mm]

Found in Colombia, Ecuador and Peru at elevations 1600 to 3800 meters as a small to large sized, cool to cold growing, densely caespitose epiphyte with slender to stout, erect ramicauls with a loose tubular sheath near the middle and 2 to 3 loose, imbricating others at the base and carrying a single, apical, erect, thickly coriaceous, elliptical, subacute to obtuse, cuneate below into the sessile base leaf that blooms in the spring on a few to many, more or less secund, arising through a broad, foliaceous spathe from an annulus adjacent to the abscission layer, 4 to 12" [10 to 30 cm] long including the .8 to 2" [2 to 5 cm] long peduncle, densely, simultaneously many flowered inflorescence with an infundibular, shorter, to as long as the ovary floral bract.

"Similar to P cassidis in many ways but differs in the dorsal sepal that is concave and three veined. The lateral sepals are more or less reflexed near the middle. The petals are broad, rounded apically and three veined. The fleshy lip is broadly oblong to ovate, more or less dilated below the middle with erect sides. The apex is broadly obtuse with the tip not decurved. The center of the lip is shallowly concave between a pair of rounded calli below the middle that are more or less continuous with the curved basal carina above the basal cavity. A third callus is sometimes present medially above the apex." Luer 1998
