Justification:
|
A terrestrial herb endemic to Ecuador. For more than a decade, the species was known from a single collection. An intensive search in 1998–1999 revealed six new subpopulations. All the subpopulations recorded to date are in croplands and pastures. Each subpopulation has 500 clumped individuals in an area less than 100 m². Three populations occur inside Ecuador’s protected areas network, all in disturbed areas of the Parque Nacional Sangay. Habitat destruction is the only known threat to the species.
