Common Name The Saw Heart Pleurothallis [refers to the serrulate margins of the petals and sepals]

Flower Size .4" [1 cm]

Found in Narino [Antioquia?] Colombia at elevations around 1800 to 2900 meters as a small to medium sized, cool to cold growing epiphyte with slender, erect ramicauls enveloped by a close tubular sheath on the lower third and 1 to 2 others at the base and carrying a single, apical, erect, coriaceous, oblong-ovate, subacute, acuminate, deeply cordate below into the sessile base leaf that blooms in the spring and fall on a .08 to .16" [2 to 4 mm] long peduncle, successively single, few flowered inflorescence arising through and concealed mostly by a spathe and has a thin, tubular floral bract.

This species is similar to and mostly intermediate between P grandiflora and P linguifera and differs mainly in the ciliate-scabrous sepals and petals. It also is similar to P adonis and P linguifera in the elongate lip with recurved sides but from these it differs in the ciliate scabrous lip.

CAUTION The species in the photo above fits Luer's description and drawing in most respects. The leaf shape here is narrowly ovate and Luer describes his plants as having oblong-ovate leaves, the other discrepancy is that the orchid in the photo above was encountered in Antioquia about 300 miles to the north of its range according to Luer.
