Trichocereus santaensis, also known as Echinopsis santaensis, is a rare Trichocereus species from the Santa Valley in Peru. It was described by Backeberg and Rauh, and its status is currently not really clear. There should be some DNA testing to investigate whether or not it deserves to be treated as a correct species and the issue is a complicated one. T. santaensis has many different regional forms, some of which get very close to other Peruvian species. Sometimes, plants have traits of more than one species and without DNA testing, it is hard to distinguish them reliably.
On this page I want to show some of the unique and beautiful populations in Peru.
Some forms are very close to Trichocereus peruvianus or Trichocereus pachanoi, while there certainly are very unique populations that might actually be a separate and correct species. For example, the forms from Ichoca, Chanca or Huata are the ones that we want to see tested via DNA testing.
