Common Name The Magdalena Pleurothallis [A river and town near where the species was first encountered]
Flower Size .2" [5 mm]
Found in Colombia and Ecuador in dense forests at elevations around 1800 to 2500 meters as a mini-miniature to small sized, cool to cold growing, caspitose epiphyte with a slender, erect ramicaul with a tubular sheath near the middle and 2 others at the base and carrying a single, apical, erect, coriaceous, narrowly elliptical, acute to subacute, narrowly cuneate below into the petiolate base leaf that blooms in the winter on an erect, arising through a spathe and an annulus below the apex of the ramicaul, strict, sublax, subsecund, 2 to 6" [5 to 15 cm] long, simultaneously several to many flowered, racemose inflorescence with an oblique, acute, as long to shorter than the ovary floral bract.
"Distinguished by the slender habit with a narrow subpetiolate base leaf about the same length as the ramicaul. The secund inflorescence of small, simultaneous flowers is often twice as long as the leaf. The sepals are free, usually light purple and glabrous, but on many specimens the external surfaces are covered by a web of hyphae, the petals are pblong and obtuse with the midvein thickened, the oblong lip is very thick with the rounded apex either smooth or lightly subverrucose and the disc is broadly channeled between a pair of perallel calli." Luer 1999
CAUTION The photo attributed to P magdalenae is closer to P bracteosa with the frilly verrucose lip so please use with caution. I await more information!
