Found in Rio de Janiero, Minas Gerais and Sao Paulo states of Brazil on rocks at elevations around 1000 meters as a small sized, warm to cool growing lithophyte with fusiform, laterally compressed, sulcate, 4 to 5 internoded pseudobulbs enveloped in youth by deciduous, imbricating sheaths and carrying usually 3, apical, erect, subcoriaceous, elliptic-elongate, apiculate, dorsally keeled, dark green leaves that blooms in the late spring on a terminal, erect, to 8" [to 20 cm] long, to 20 flowered inflorescence arising through a short spathe and carrying non-resupinate flowers.
Cited as a synonym of P vespa , I have kept it separate because Marcos Campacci is adammant that it is a different species.
