A terrestrial herb endemic to Ecuador, and one of the famous species discovered on Cerro El Centinela by A. Gentry and C. Dodson in the 1970s and 1980s. The pessimistic name of the species is due to the fact that El Centinela forest was destroyed after the collections were made and the species has not been collected since. Known from four collections on El Centinela, located east of the Río Palenque private reserve, at km 12 of the Patricia Pilar-Flor de Mayo road. No specimens of this species are housed in Ecuadorean museums. Apart from habitat destruction, no specific threats are known.
