"Characterized by a stout ramicaul and an inflated, spotted spathe at the base of the thickly coriaceous leaf. The sepals are very thick and pubescent externally with a long pubescent ovary. The petals are obovate with a thin carina above the lower margin reminiscent of Masdevallia. The lip is more or less standard for the subgenus with a pair of calli on the middle third within the forward margins of low, lateral lobes and a minutely biauriculate base." Luer 2004

"The type states Oaxaca Mexico? without collection data as the type location, most likely in error." Luer & Toscano 2015
