Common Name The Double Pleurothallis [refers to the similarity to the dorsal sepal and the synsepal]

Flower Size .3 " [1 cm]

Found in Norte de Santander Colombia at elevations of 1730 to 2200 meters as a mini-miniature to small sized, cool to cold growing epiphyte with slender, erect, sharply ancipitous above the middle ramicauls with a tubular sheath below the middle and 2 to 3 others at the base and carrying a single, erect, rigid, coriaceous, ovate, acute, externally carinate, rounded and subcordate below into the sessile base leaf that blooms in the later spring and again in mid fall on a fascile of filiform, .4 to 1" [1 to 2.5 cm] long, successively single, few flowered inflorescence arising through a reclining spathe above the base of the leaf.

Luer states that this species is unique in the genus for the winged column which the photo above has, he also states that P duplex has a pair of triangular lobes towards the base of the lip which the photo has as well. What does not match Luer's description in the photo is the flower color and the location of the plant, Luer has the colors as light yellow for the petals and sepals and the lip as white, he states that this species is endemic to Norte de Santander on the easrtern side of the eastern cordillera. This plant was photographed in the Valley de Sibundoy which is hundreds of miles south of Norte de Santander but it is still the eastern side of the eastern cordillera. Anyone?
