Common Name The Incompatible Pleurothallis [refers to its strange morphological features]

Flower Size .2" [5 mm]

Found in Valle de Cauca department of Colombia at elevations around 2400 meters as a small sized, cold growing, caespitose epiphyte with slender, erect ramicauls enveloped by a thin, tubular sheath below the middle and 2 to 3 others at the base and carrying a single, apical, erect, coriaceous, ovate, acute, slightly acuminate, long-mucronate, broadly cuneate to rounded below into the sessile base leaf that blooms in the late fall and early winter on 1 to a few, arising through a slender spathe at the base of the leaf, erect, lax, 1.6 to 2" [4 to 5 cm] long including the .8 to 1.2" [2 to 3 cm] long peduncle, simultaneously few flowered inflorescence with an infundibular, shorter than the ovary floral bract.

"The combination of morphological features of the flower of this species seems contradictory, failing to indicate a close relationship with any other species of Pleurothallis. The habit is compatible with either subgenus Pleurothallis section Pleurothallis or subgenus Specklinia section Acuminatae. It is characterized by a long, slender ramicaul with thin, close sheaths and an ovate leaf. The loose, few-flowered raceme is a little shorter than the leaf. The dorsal sepal is obtuse and concave. The lateral sepals are fully connate into a flat, oblong synsepal, which excludes section Acuminatae. The petals are spathulate, a common character seen in many subdivisions of the genus. The more or less truncate lip with incurved sides and intramural calli suggest subgenus Crocodilanthe, but the habit and elongate column are incompatible. The lip also suggests section Truncatae of Pleurothallis where it seems most closely allied with a few, unusual species: P. leopardian , P. divaricans , P. tanyrhina , and P. truncata .
