Common Name The Dainty Pleurothallis
Flower Size .2" [6 mm]
Found in Nariño department of Colombia and Pichincha, Esmeraldas and Imbaburra provinces of Ecuador at elevations around 400 to 1800 meters as a miniature to small sized, hot to cool growing, caespitose epiphyte with very slender, erect to suberect ramicauls enveloped by a thin, tubular sheath below the middle and another at the base and carrying a single, apical, erect, thinly coriaceous, ovate, acute, rounded to subcordate, sessile base leaf that blooms at most any time of the year on a delicate, flexible, 2.4 to 3.2" [6 to 8 cm] long, loose, several flowered, racemose inflorescence arising from a spathe at the base of the leaf.
"Distinguished by the very delicate raceme of fragile, little flowers that hangs over the edge of the thin, ovate leaf. The acute sepals are found in various colors with or without spots . The petals are usually narrowly linear, but occasionally slightly broader "leaves" sic [petals?] with an additional, incomplete vein are seen. The basal lobes of the tiny lip flanks the column."
