Common Name The Antenna Bearing Pleurothallis [refers to the erect petals]
Flower Size .2" [5 mm]
Found in Colombia, Ecuador, Peru and Bolivia at elevations of 2400 to 3350 meters as a small to medium sized, cold growing, repent epiphyte with slender, occasionally proliferating, ascending to erect ramciauls enveloped by a tubular sheath above the middle, another below the middle and another at the base and carrying a single, apical, erect, coriaceous, elliptical-ovate, acute, broadly cuneate below into the sessile base leaf that blooms in the spring and summer on 1 to 2, erect, strict, arising through a spathe, subcongested, secund, 2.8 to 11.2" [7 to 28 cm] long, simultaneously many flowered, racemose inflorescence with an oblique, acute, shorter to as long as the pedicel floral bract.
This species is easily recognized by the usually repent rhizome, the long erect ramicauls with a sheath above the middle and another below the middle, and 1 to 2, densely flowerwed racemes of yellow to green flowers with very narrow petals that are as long as the sepals and protrude from either side. The lip is three-lobed and has incurved lateral lobes that vary in length and width.
