Common Name Alvaro Mejia's Pleurothallis [Colombian orchid grower]

Flower Size .4" [1 cm]

Found in Antioquia department on the central cordillera of Colombia near Medellin as a small sized, cool to cold growing, caespitose to shortly repent epiphyte at elevations around 2000 meters with stout, erect ramicauls enveloped basally by 2 to 3 tubular sheaths with another below the middle carrying an erect, coriaceous, ovate, acute, lightly acuminate leaf with a sessile base and broadly cuneate that blooms in the spring in cultivation on an erect-arching, subtended by a reclining spathe loose, distichous, 5.5 to 6" [14 to 20 cm] long, simultaneously opening, several flowered inflorescence with infundibular, thin, much shorter than the pedicel floral bracts.

"Distinguished by the large, sessile, ovate leaf borne by a well developed ramicaul and a loose raceme of relatively large flowers. The color varies from yellow to purple. It is similar to P supervacanea both vegetatively and florally but is distinguished by the broader, narrowly obtuse sepalas, broader petals and an ovate lip with a pair of small, central calli instead of intrmarginal calli of the lateral lobes and without the transverse callus above the base." Luer 1998
