Trichocereus litoralis is definitely closely related to Trichocereus chiloensis and the current taxonomy is treating it as a variety or subspecies to it. Trichocereus litoralis always was a problematic species because there are so many intermediate forms between Trichocereus chiloensis and Trichocereus litoralis that it is extremely difficult to draw the line somewhere. While some treat it as part of Trichocereus chiloensis, some others disagree and treat it as a separate species. Personally, I think that the whole group of plants surrounding Trichocereus chiloensis is very variable and we should simply respect that plants can be related to each other and at the same time, look a little bit different. The species is also very closely related to Trichocereus skottsbergii, which I also regard as a variety of Trichocereus chiloensis/Echinopsis chiloensis.

Have a look at this beautiful picture of Trichocereus litoralis growing along the coast line in Chile.
The flower of Trichocereus litoralis is extremely beautiful and can be used in hybrid breeding. Unfortunately, those plants take very long until they reach adulthood.
