A terrestrial herb endemic to Ecuador. One of the dozens of species collected by L. Sodiro near Quito at the beginning of the twentieth century that has never been collected again. The only known population, reported by Sodiro in "sandy fields near Quito," is likely extinct due to urban growth. One of the only arguments in favor of not classifying the species as extinct is its weedy appearance, which may have contributed to the lack of recent collections. The type was apparently destroyed in the Berlin herbarium during the Second World War, but a photograph is held by the Field Museum. No specimens of this species are housed in Ecuadorian museums. Habitat destruction is the only known threat to the species.
Date last seen: early 20th century
