A vine endemic to Ecuador's northern Andes, where it is known from two populations. Discovered in 1935–1937 by E. Asplund in the Cordillera de Huacamayos, on the way to Urcusiqua and probably inside what is now the Reserva Ecológica Antisana. The second population is close to the Colombian border, at Maldonado. The principal threats are fires, grazing and logging.
