Common Name The Rigid Pleurothallis
Flower Size .4" [1 cm]
Found in Peru at elevations of 1200 to 1500 meters as a small sized, cool growing epiphyte with erect ramicauls enveloped by 2 to 3, close, tubular, evanescent sheaths and carrying a single, apical, erect, ovate to ovate-elliptic, rounded to obtuse, broadly cuneate below into the channeled, petiolate base leaf that blooms on an abbreviated, arising through a prominent, conduplicate spathe, successively single, few to many flowered inflorescence with thin, tubualr, much shorter than the pedicel floralbract.
Differs from the similar and often synomonous P hitchcockii in the purple striping on all parts, divergent lateral sepal apices, the much wider distance between the 2 calli on the lip, the recurved apex of the lip and the much lower wing-like side lobes of the lip
CAUTION this species is almost always cited as a synonym of P hitchcockii but if this determination is correct then they are quite different. I await better references to decide if it is separate or not.
