Accepted name and source opinion
Kew POWO accepts Ariocarpus fissuratus with the author citation (Engelm.) K.Schum.; its native range is southwestern and southern Texas to northeastern Mexico, with Jalisco included by POWO in desert or dry-shrubland context.1 IPNI remains separate evidence for nomenclatural publication and basionym details.2 The accepted combination is the 1894 Natürlichen Pflanzenfamilien record; IPNI gives the 10 July 1894 date and detailed collation. The sources agree on the 1894 combination; IPNI supplies more detailed collation. 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. A broad flattened body, fissured-looking triangular tubercles and woolly grooves create a cryptic, soil-level habit.
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 14 synonyms: two homotypic names plus heterotypic names around lloydii, pailanus, intermedius and minor. 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. bravoanus, A. kotschoubeyanus, A. agavioides and selections such as “Godzilla” are not species synonyms. 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
The body can blend into rocky calcareous ground; the broad range does not imply identical microhabitat. POWO records the native range as southwestern and southern Texas to northeastern Mexico, with Jalisco included by POWO.1 This does not describe commercial production, and nursery availability is not evidence that wild populations are secure.
The IUCN-linked target is LC; the former live value was VU.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.
