Reviewer(s): Valencia, R., Pitman, N., Léon-Yánez, S. & Jørgensen, P.M. (Ecuador Plants Red List Authority)
Justification:
A terrestrial herb endemic to Ecuador, where it is known from two collections. The species was collected in Bolívar province at Las Palmas-Tomboloma some time before 1908, and subsequently in Pichincha province at km 21 of the Calacalí road, in 1979. Not known to occur inside Ecuador’s protected areas network, but may occur inside the Reserva Geobotánica Pululahua due to similar climatic conditions of the historical collection sites. The principal threat is the conversion of native vegetation to croplands. No specimens of this species are housed in Ecuadorian museums. Habitat destruction is the only known threat to the species.
