A shrub endemic to Ecuador, where it is known only from the type specimen, collected near Naranjito, Guayas province, in 1945. Probably locally extinct there, but new studies should be carried out in the several dry vegetation remnants of the area now protected by bosques protectores and private reserves. No specimens of this species are housed in Ecuadorean museums. Apart from habitat destruction, no specific threats are known.
