Common Name or Meaning The Two Callous Pleurothallis [refers to the lip]

Flower Size .2" [5mm]

Found in Carchi province of Ecuador at elevations around 1800 meters as a miniature sized, cool growing epiphyte with slender, erect, ramicauls with an inflated tubular sheath near the middle and 2 to 3 others at the base and carrying an erect, single, coriaceous, elliptical-ovate, acute, cuneate below into the petiolate base leaf that blooms in the summer on a dense fascile, arising through a fugaceous spathe at the base of the leaf, of numerous, .4" [1 cm] long, simultaneously opening 1 to 2 flowered inflorescence with thin, infundibulbar, acute, acuminate, deeply concave, just shorter than the pedicel floral bracts.

"Similar in habit to P ruscifolia but the flowers of P bicallosa are somewhat larger but with the same sepals and petal shape. The lip is subquadrate and larger than the lip of P ruscifolia and a well developed apiculum decurves abruptly from the broad anterior margin. The base is not at all deflexed as seen in P ruscifolia. Most distinctive is the pair of erect, subacute calli on the center of the disc." Luer 1998
