TYPE Drawing by Carl Luer

Common Name The Little Skull Pleurothallis [refers to the synsepal]

Flower Size .2" [5 mm]

Found in Cauica and Norte de Santander departments of Colombia and Carchi and Imbabura provinces of northern Ecuador at elevations of 2000 to 3100 meters as a small to medium sized, cold growing, caespitose epiphyte with slender, erect, coriaceous, narrowly elliptical, acute, cuneate below into the petiolate base leaf that blooms in the winter and spring on a pendant, arising through a spathe below the base of the leaf, slender, [3 to 4 cm] long, few flowered, racemose inflorescence and has ainfundibular, longer than the pedicel floral bract.

"Similar to P bicornis but differs in the lip that is acutely deflexed upon itself near the middle and the margins are entire. The flowers of P calvariola are smaller than those of the plant described as P silvestris but otherwise appear the same and therefore it is considered to be a synonym of P calvariola." Luer 1999
