Botanical and organ identity
Separate source taxon identification from recognition of the harvested organ.
Source plant and cladode
Establish the plant relationship and evidence that the material is a cladode.
- What observations or source records establish the plant's taxon, and with what confidence? provenance

What it is Filled
Nopal is a flattened stem segment, or cladode, of a prickly-pear cactus of the genus Opuntia, especially Opuntia ficus-indica, commonly eaten as a vegetable when young and tender.
In scope
- Regional, botanical and commercial usage relevant to identifying a cactus pad as nopal is in scope.
- Cladode identity and its relationship to the source plant are in scope.
- Pad maturity, dimensions, tenderness and tissue condition are in scope.
- Spine and glochid presence and removal state are in scope.
- Harvest provenance, storage history and preparation state are in scope.
- Evidence supporting a proposed food, planting or other use of the pad is in scope.
Out of scope
- Complete taxonomy and life cycle of the source cactus species
- Prickly pear fruit as a separate harvested organ
- Cultivation enterprises and plantation management
- Recipes and prepared dishes containing nopal
- Extracts, supplements and therapeutic efficacy claims
- Complete livestock diets incorporating cactus material
Why it exists Filled
Enable an agent to identify nopal, assess its physical condition and preparation state, and determine suitable handling or use from documented identity and provenance.
Distinguishing features Filled
- Assign this record to cactus pad material rather than to a whole cactus or a mixed prepared dish.
- Establish cladode identity rather than treating a flat green organ as sufficient identification.
- Distinguish a stem pad from the cactus fruit by organ identity and attachment evidence.
- Record source species independently: the common name alone does not establish a species determination.
- Distinguish intact pad material from powders, extracts and mixed dishes whose processing requires neighbouring models.
What robots and AI may and may not do Filled
Must not
- Recommend nopal as a cure for diabetes or other diseases without clinical evidence.
- Help introduce Opuntia into regions where it is a declared invasive weed.
- Collect wild pads from protected land without permission.
- Misrepresent the cultural significance of nopal in Mexican heritage.
Only with a human decision
- Planting or moving viable pads in a region where Opuntia is regulated as invasive requires human oversight.
May
- Identify nopal pads and describe their documented food uses and preparation state.
- Describe hazards associated with spines and glochids without giving preparation instructions.
- Record pad provenance, source plant identity and cultivated or wild origin.
Moral aspects Filled
- Nopal is central to Mexican food culture and national symbolism.
- Opuntia has become a damaging invader in some countries.
Who is affected
- People who eat it
- Farmers and growers
- Ecosystems where it is invasive
Owners Filled
Steward
Growers or land managers are responsible for attached pads within their remit, and harvesters, suppliers or holders are responsible for harvested pads in their custody.
Master systems
- Harvest, inventory and food traceability records document harvested pads where available.
- Herbarium and biodiversity occurrence databases can document source plant identity and provenance.
