Scientific taxonomy article
Accepted name and source opinion
Kew POWO accepts Echinopsis pachanoi with the author citation (Britton & Rose) H.Friedrich & G.D.Rowley; its native range is South Ecuador to Peru.1 Kew records the native range from southern Ecuador to Peru; documented introduced regions are not presented as native range.
Placement and production lineage
The production lineage is species → Echinopsis → Trichocereeae; the Cactaceae family context remains higher in the ancestry chain. This source owns only the existing species node and its direct genus relationship; it creates no family, order, subfamily or tribe nodes. A tall branching columnar body, rib profile, areoles, spination, flowers and provenance should be evaluated together; juvenile proportions should not be confused with mature plants.
Identification cannot be reduced to one product photograph, flower colour or body proportions altered by cultivation. Ribs, areoles, spines, flowers, growth form and reliable provenance should be evaluated together.
Synonymy and canonical boundary
Kew represents 10 nomenclatural source records in 10 unique name+author synonym rows. Kew lists 10 synonyms; historical Trichocereus and Cereus combinations support search and literature retrieval but are not separately accepted species routes. Homotypic and heterotypic names support search and literature retrieval but are not separately accepted species routes.
Editorial content is limited to botanical identity and high-level toxicity, legal and safety cautions; it contains no preparation, consumption, extraction, dosage or procurement guidance.
Range and conservation
The native range is recorded as South Ecuador to Peru.1 Nursery origin and commercial inventory are not evidence about wild populations.
The sourced conservation target is LC; the former live value was empty.2 The official IUCN-linked target is LC, replacing the former empty live value; the correction belongs only to the botanical conservation field.
Editorial ownership boundary
Product copy, price, stock, SKU, images, variants, categories, common names, slugs and the product-to-botanical link are not changed by this taxonomy-only source. Live toxicity, difficulty and light enums remain unchanged; watering, temperature and soil metrics are omitted from the curated payload and carried forward from live data. The accepted epithet may be populated as “pachanoi”, while empty subfamily and tribe fields are not guessed.
