Justification
A terrestrial herb endemic to Ecuador, where it is known from a single historical collection from some time before 1854. The species is named after the city of Quito but was discovered near the city of Ibarra. Not known to occur in Ecuador’s protected areas network and possibly Extinct due to disorganized growth around Ibarra. No specimens of this species are housed in Ecuadorean museums. Apart from habitat destruction, no specific threats are known.
