A leading hypothesis for the pachanot's origin is the material Robert Field's father received from Harry Blossfeld in 1935; Blossfeld sold 12 shares in his collecting expedition to finance it, and supporters including Field received a large volume of live cactus that resembles the pachanot, which could explain its abundance in the USA, Europe, and Australia. DNA analysis is proposed to confirm or reject this. [Pachanoi or Pachanot? (Keeper Trout, Trout's Notes)]
An alternative origin hypothesis is that a collector such as Paul C. Hutchison or Harry Johnson Jr. collected or produced a naturally occurring pachanoi x bridgesii hybrid from Bolivia, whose wild parent population may have been extirpated during 1970s Bolivian government efforts to reduce urban stands of mescaline-containing cacti. [Pachanoi or Pachanot? (Keeper Trout, Trout's Notes)]
Clone genealogy
The pachanot appears to be propagated entirely vegetatively (a single clone) despite freely flowering and readily hybridizing. [Pachanoi or Pachanot? (Keeper Trout, Trout's Notes)]
