Assessor(s): Oleas, N. & Pitman, N.
Reviewer(s): Valencia, R., Pitman, N., Léon-Yánez, S. & Jørgensen, P.M. (Ecuador Plants Red List Authority)
Justification:
A terrestrial herb endemic to Ecuador. Despite intensive searches in 1998–1999, this species is still restricted to the Pastaza river valley in the province of Tungurahua. Subpopulations are found from the Bascún stream on the slopes of Tungurahua volcano to the Río Negro on the Baños-Puyo road. The species inhabits disturbed areas like roadsides, pastures and cliffs, where it forms clumps of fewer than 100 individuals. Some subpopulations have been affected by the widening of the Baños-Puyo road. Another potential threat is commercial exploitation as ornamental plants, though it is unknown if the bulbs sold internationally are wild or cultivated in origin. Not confirmed to occur in Ecuador's protected areas network, but potentially present in the high portion of the Parque Nacional Sangay. This species was listed as Rare in 1997. Habitat destruction is the only known threat to the species.
