Common Name The Aborted Pleurothallis [refers to the absent column foot]

Flower Size .2" [5 mm]

Found in Nariño department of Colombia in cloud forests at elevations around 1950 meters as a miniature to small sized, densely caespitose, cold growing epiphyte with slender, erect ramicauls enveloped by a close tubular sheath below the middle and 2 to 3 others at the base and carrying a single, apical, erect, coriaceous, narrowly linear-ovate, acute, cuneate below into the sessile base leaf that blooms in the fall on a lateral, arising through a spathe at the base of the leaffascile of slender, .16 to .2" [4 to 5 mm] long, successively single flowered inflorescence and has tubular, shorter than the ovary floral bracts.

"Differs from all in the subgenus by the very small a membraneous, vestigal lip that clings to the undersurface of the much larger, cylindrical column and simply attached to the base. Resembling manys species of Lepanthes, the lip is attached to the base of the terete column without a foo." Luer 1998t
