Accepted name and source opinion
Kew POWO accepts Ariocarpus agavioides with the author citation (Castañeda) E.S.Anderson; its native range is Mexico, from Tamaulipas to San Luis Potosí in desert or dry-shrubland context.1 IPNI remains separate evidence for nomenclatural publication and basionym details.2 POWO displays E.S.Anderson and volume 99; IPNI displays E.F.Anderson, volume 49 and the original spelling “agavoides”. The author initials, volume and original-spelling difference remain source-separated. The difference stays source-attributed in metadata rather than being collapsed into an invented reconciliation.
Placement and identification
Ariocarpus is an accepted genus in the Cactoideae–Cacteae context of Cactaceae.3 The species node owns only its direct Ariocarpus parent; order, family, subfamily and tribe nodes are not recreated. Long narrow agave-like tubercles, a small body and flowers emerging from the centre create a distinctive morphology.
Identification cannot rely on flower colour or one product photograph. Tubercles, epidermis, areoles, spines, flowers, fruits, the thickened root and reliable provenance should be evaluated together. Grafting, heavy feeding, low light and warm winters can alter body proportions without automatically changing scientific identity.
Synonymy and canonical boundary
Kew lists 6 synonyms: two homotypic names plus four heterotypic subordinate-rank names around pulcher and sanluisensis. Homotypic names share one nomenclatural type, while heterotypic names can be based on different historical types. They support search and literature retrieval but do not create separately accepted species routes.
A. kotschoubeyanus remains separately accepted; the former subordinate placement does not merge the species. Related species, commercial clones, colour selections and product labels are excluded unless the maintained source treats them as synonyms. This prevents SEO pressure from merging species or publishing former subordinate ranks as new canonical routes.
Range and conservation
Its narrow northeastern Mexican range and dry-shrubland context remain separate from nursery inventory. POWO records the native range as Mexico, from Tamaulipas to San Luis Potosí.1 This does not describe commercial production, and nursery availability is not evidence that wild populations are secure.
The IUCN-linked target is EN; the former live value was CR.4 The correction belongs only to the botanical conservation field, not product eligibility, legal trade or inventory.
Production ownership
The source defines only the target taxonomy node and linked botanical editorial fields. Product copy, price, stock, SKU, images, variants, categories, common names, slugs and the product-to-botanical link remain protected. A placeholder botanical image is not replaced in this batch.
