A shrub endemic to Ecuador, where it is known from a single collection in Puente de Chimbo, Guayas province, recorded by L. Sodiro more than 100 years ago. If the species is not extinct, additional collections may occur in the dry forest of the Bosque Protector Cerro Blanco, Capeira and other remnants. Considered Critically Endangered due to the drastic alteration of its habitat since its discovery. No specimens of this species are housed in Ecuadorean museums. Apart from habitat destruction, no specific threats are known.
