A shrub endemic to Ecuador's southern Andes. Discovered in the early nineteenth century and rediscovered 150 years later, in 1982, on a dry, eroded ridge 5–7 km west of Santa Isabel, Azuay province. Although the collector mentions that the species was dominant in the area, there have been no new collections since. Additional populations may occur in the Parque Nacional Cajas. There is a dubious report from a forest in Manabí, which needs confirmation. No specimens of this species are housed in Ecuadorean museums. Apart from habitat destruction, no specific threats are known.
