Flower Size 1/4" [6 mm]

Found as a terrestrial or an epiphyte in Ecuador at elevations of 600 to 3000 meters and is a small sized, highly variable plant of climates and terrain. Grows best cold to warm. This species has an erect, slender ramicaul enveloped basally by 2 to 3 sheaths and carries a single, apical, cordate, acute leaf and blooms in the winter on a very short, successively flowered inflorescence carrying a single flower held close to the leaf base.

Similar to P grandiflora but has much smaller flowers [about 1/4 the size] and have a three veined dorsal sepal, petals that lie more or less parrelllel to the lip and the sides of the lip pare deflexed above the middle as the apex humps up.

P deflexa is similar to P siphoglossa, P linguifera, P millei, P grandiflora and P sarcochila in the large sized flowers.
