A shrub endemic to Ecuador, where it is known only from the 1933 type collection. The type locale is the Río Pastaza valley, near the town of Río Negro, and between the Parque Nacional Llanganates and the Parque Nacional Sangay. May be a synonym of another species, because the holotype was apparently destroyed in the Berlin herbarium during the Second World War. No specimens of this species are housed in Ecuadorean museums. Apart from habitat destruction, no specific threats are known.
