Common Name or Meaning Barthelemy's Pleurothallis [French botanist and co-collector of species]
Flower Size .2" [5 mm]
Found in French Guyana at elevations around 100 meters as a mini-miniature sized, hot growing, shortly repent epiphyte with slender, erect to suberect ramicauls with a close tubular sheath below the middle and 2 to 3 others at the base and carrying a single, erect, thickly coriaceous, narrowly elliptical, acute, narrowly cuneate below into the sessile base leaf and blooms in the winter on short, congested, erect, to .4" [1 cm] long including the .04 to .2" [1 to 5 mm] long peduncle, few flowered inflorescence arising through a spathe at the leaf base.
Luer combined this species, P purpurescens and P nanella into P erebatensis, I have split them apart as the plants and flowers really are quite different. He compared it to P lojae but differs in the prominent mentum at the base oof the lateal sepals and a lip widest above the middle with much smaller crests and clawed below the middle.
