There is not a clear line between Trichocereus macrogonus and Trichocereus peruvianus but these are some plants that I received as or I consider to be Trichocereus macrogonus.
Here are the plants categorized as Trichocereus validus, Trichocereus terscheckii, Trichocereus taquimbalensis, Trichocereus tacaquirensis, and Trichocereus werdermannianus
