Common Name Ortega's Pleurothallis [Ecuadorian co-discoverer of species current]

Flower Size .4" [1 cm]

Found in Ecuador at elevations of 1500 to 2300 meters as a small to medium sized, cool to cold growing, caespitose epiphyte with slender, erect ramicauls enveloped basally by 2 close, tubular sheaths and another on the lower third and carrying a single, apical, coriaceous, acutely deflexed, cordate-ovate, acute, basally sessile, more or less concave and deeply cordate leaf that blooms in the winter, late summer and early fall on a fascile, arising through an erect to suberect, conduplicate spathe, of successive single, few flowered inflorescence with a tubular, as long as the pedicel florla bract and holding the flower close against the leaf base

Similar to P cardiostola but differs in the broad, obtuse, glabrous sepals, the entire, glabrous, sagittate, unguiculate petals and a transversely cordate, concave lip with an obtusely, acuminate apex with a thickened margin with the inner suface being cellular-papillose.

Part of the Pleurothallis cardiostola/Pleurothallis lilijae complex.
