"Characterized by the comparitively large habit with narrowly elliptical, petiolate leaves and a long, secund inflorescence of flowers, several of which are open simultaneously. The dark purple flowers are long-pubescent within. The obtuse petals and lip are small. Most characteristic are the small, erect, subquadrate lobes of the lip. THe anterior corner of the truncate apex is slightly proplonged. A prominent pair of lamellae occupy the middle third of the lip and a small pair of adjacent lamellae are present at the base."

Similar to P canae, P segoviensis and P pilostoma but differs in the narrow and convex synsepals and the lobes of the lip are small and longer than broad.
