Common Name The Little Red Pleurothallis

Flower Size .4" [1 cm]

Found in Colombia without location and Zamora-Chinchiope, Napo and Pataza provinces of Ecuador at elevations of 600 to 1400 meters as a miniature to small sized, hot to warm growing, caespitose epiphyte with slender, erect ramicauls enveloped basally by 2 to 3, closely apressed, thin, tubular sheaths and another below the middle and carrying a single, apical, horizontal, coriaceous, ovate, acute, basally sessile and cordate that blooms in the spring on a fascile of short, successive single flowered inflorescence arising through a reclining spathe and has a thin, tubular, shorter than the pedicel floral bract.

Often cited as a synonym of P phyllocardioides but distinguished by the larger, red-purple flowers with proportioanlly longer and narrower petals. The flowers are characterized by subacute sepals, narrowly linear-oblong, minutely erose petals and an ovate, obtuse to subacute lip. P phyllocardioides flowers are yellow and no yellow flower has ever been found of P erythrium." Luer 2005
