Common Name The Beaker Pleurothallis [refers to the lip which appears to have a spout]

Found in Cundinamarca department of Colombia and El Oro province of Ecuador at elevations around 600 to 1100 meters as a miniature sized, warm growing, caespitose epiphyte with erect, slender ramicauls enveloped by a close tubular sheath below the middle and 2 to 3 others at the base and carrying a single, apical, horizontal to spreading, thinly coriaceous, cordate-ovate, acute, shallowly cordate below into the sessile base leaf that blooms in the summer and fall on a fascile of several, arising through a reclining spathe, .24 to .4" [.6 to 1 cm] long, successively single flowered inflorescence with a shorter than the pedicel floral bract.

"Vegetatively similar to many others with small, shallowly cordate leaves but the clear-yellow, glabrous flower is distinguished by the conspicuous, obovate, obtuse, trinerved petals , an ovoid deeply concave lip and a short, thick column with a spall apical anther. The lip of flowers from Colombia are shortly acuminate while those from Ecuador are simply acute." Luer 2005
