Well, KK339 is a clone that's been propagated from cuttings of one unique individual trichocereus pachanoi in horticulture. KK338 has not to my knowledge been distributed as cutting material very widely and Karel Knižes' collection numbers often refers to different plants in a specific area and not material from one geneticaly identical clone. I've seen so many different seedgrown types of KK338, KK339 and KK242. In europe most of the KK242 are a type of very glaucous T. Cuzcoensis.
A very good idea to put together a list. Here are some clones circulating europe, thought they might be available in Aus too?
Trichocereus Pachanoi/Bridgesii "super silver blue form" a very glaucus thin pach/bridge cross sold as cuttings.
Trichocereus Bridgesii "Hotel" Not very much info on this.
Trichocereus Pachanoi "Kimnach"
Trichocereus Pachanoi "Lima Flower Market" Collected by MT, maybe the same material as Ogun?
