The taxon long known horticulturally as Trichocereus peruvianus is treated by POWO/Kew as a synonym of Echinopsis macrogona (basionym Cereus macrogonus Salm-Dyck; accepted combination by H.Friedrich & G.D.Rowley). Trichocereus macrogonus (Salm-Dyck) Riccob. and Echinopsis peruviana are also synonyms of Echinopsis macrogona. A 2012 revision sank both T. peruvianus and T. pachanoi into T. macrogonus, but pachanoi has since been treated again as the separate species Echinopsis pachanoi.

Native range
Echinopsis macrogona is native to Bolivia and Peru, with the suggestion in the literature that its original native distribution may be only the high valleys of Peru and perhaps northwestern Bolivia. [https://en.wikipedia.org/wiki/Echinopsis_macrogona]
Conservation
Echinopsis macrogona carries an IUCN Red List status of Least Concern (criteria 3.1), and as a cactus is covered under CITES Appendix II. [https://en.wikipedia.org/wiki/Echinopsis_macrogona; https://www.kew.org/sites/default/files/2019-09/CITESandCacti_full.pdf]
