Research draft, second pass
A second pass drafted this model: the structure a model of this thing needs, and what is known about it in the world. The line under this one says how the second half was obtained - researched against sources, or recalled without web access, in which case nothing here was read anywhere and every claim is a lead to verify.

Purpose and description
Enable an AI agent to recognise Trigonella foenum-graecum, assess the condition of its plants and identifiable harvested parts, and determine whether propagation, harvest, storage or referral for use assessment is justified.
Trigonella foenum-graecum L. is an annual diploid (2n = 16) Fabaceae crop whose hard, angular seeds and aromatic leaves are the commercial fenugreek commodity, chemically marked by the steroidal sapogenin diosgenin, the alkaloid trigonelline, and the sotolon-driven maple/celery odour of the seed.
It can be Compare leaves, flowers and pods with authenticated botanical references and retain a provisional determination when evidence is incomplete.; Track development and organ-specific symptoms to request targeted inspection or cultivation advice.; Select traceable seed for a documented germination trial and record resulting seedlings.; Assess leaf or pod harvest readiness against the intended material and an explicit harvest criterion.; Separate harvested material by identity confidence, maturity and observed damage, and request moisture or contamination testing.; Route a proposed food, sprouting, feed or medicinal use to the appropriate assessment using the actual plant part and processing history..
Distinguishing features
Check the combination of trifoliolate leaves and obovate or oblong leaflets with teeth toward the upper margins; clover-like foliage alone does not establish identity. [PROSEA](https://prosea.prota4u.org/view.aspx?id=601)
Look for one or two pale yellow or white flowers in leaf axils; record flower placement as well as colour when testing a clover or other trifoliolate-legume identification. [Kew](https://powo.science.kew.org/taxon/urn%3Alsid%3Aipni.org%3Anames%3A523957-1/general-information)
Inspect mature fruits for long, narrow, straight to sickle-shaped pods ending in a conspicuous beak; document pod shape and beak separately when comparing other legumes. [PROSEA](https://prosea.prota4u.org/view.aspx?id=601)
Require a regional botanical key or authenticated reference to resolve similar Trigonella specimens; a common name, aromatic sample or vegetative photograph alone remains a provisional identification.

Characteristics
- Identification support
- unassessed | provisional | supported | conflicting; record determiner, method and evidence Controls whether the agent can attribute observations or harvested material to this species.
- Observed botanical material
- whole plant | shoot | leaf | flower | pod | seed | mixed parts Determines which identity tests and condition assessments are available.
- Leaflet configuration
- leaflet count, shape and margin description; observation unavailable permitted Provides vegetative identification evidence without treating trifoliolate foliage as conclusive.
- Flower arrangement and colour
- flowers per leaf axil; observed corolla colour Adds reproductive evidence to distinguish superficially similar foliage.
- Pod and beak dimensions
- mm; record pod length, width and beak length with maturity and sample size Makes diagnostic fruit evidence comparable without assuming one universal size threshold.
- Developmental stage
- ungerminated seed | seedling | vegetative | flowering | pod filling | mature pods | senescent; stages may coexist Separates expected seasonal change from damage and supports harvest timing.
- Accession and parent material
- links to cultivar or accession records, source seed and parent plants; unknown allowed Preserves identity through sowing, selection and harvest.
- Plant injury and symptoms
- affected organ, symptom, extent and observation date; suspected cause recorded separately Supports investigation without converting yellowing, wilting or lesions into an unsupported diagnosis.
- Seed germination performance
- % germinated and % normal seedlings, with protocol, duration, sample size and test date Supports propagation decisions using tested performance rather than appearance alone.
- Harvested seed moisture
- % water by mass; specify wet or dry basis, method and sampling date Supports drying and storage assessment when a suitable target specification is available.
- Material integrity
- intact | damaged | visibly mouldy | insect affected | mixed | unassessed; record observed proportions Separates material suitable for further assessment from material requiring isolation or investigation.
- Proposed use and supporting assessment
- propagation | leaf food | seed food | sprouting | feed | medicinal processing | research; link applicable assessment Prevents botanical identity or successful germination from being treated as approval for every use.

Drafted structure
Bundle to layer to finding to question, as the second pass will find it: 5 bundles · 9 layers · 16 findings · 31 questions.
Fenugreek identity Evidence that an observed plant or harvested part belongs to Trigonella foenum-graecum.
The registry supplies a name without a definition, while trifoliolate foliage and common-name labels provide incomplete identification.
Vegetative and floral evidence
Joint assessment of leaflet characters and axillary flowers.
Combined botanical determination
Record observed characters, their agreement with a cited botanical treatment and any competing identification.
- Do leaflet number, shape and margins, together with flower placement and colour, support Trigonella foenum-graecum under the selected botanical reference? definition
- Which determiner, photographs, voucher or authenticated comparison supports the identification? provenance
- Which similar local Trigonella or other trifoliolate legume remains unresolved because a diagnostic organ is missing? boundary
Pod and detached-material evidence
Reproductive identification and identity continuity after harvest.
Fruit-supported material identity
Record pod form and dimensions where available, and the evidence connecting detached leaves or seeds to an identified plant.
- What are the mature pod's curvature, width, length and beak length, and how many pods were examined? measurement
- Can these detached leaves or seeds be traced to an identified plant or authenticated reference sample? provenance
- Does fragmentation or mixing require additional authentication before a species determination can be accepted? action
Development and harvest The plant's developmental trajectory and readiness for the intended leaf or seed harvest.
A fenugreek plant can supply different organs, so maturity must be judged against the intended harvest rather than one generic readiness state.
Phenology and condition
Observed development alongside organ-specific signs of stress or injury.
Stage-aware condition assessment
Distinguish recorded developmental change from symptoms requiring investigation, without assigning an unverified cause.
- Which plants or shoots are vegetative, flowering, filling pods or senescent at this observation? measurement
- Are yellowing, wilting, lesions or pod damage consistent with the recorded stage, or is their cause unresolved? boundary
- Which additional inspection or test would distinguish the suspected causes before intervention? action
Organ-specific harvest
Separate readiness criteria for leaf material and mature seed.
Harvest purpose and readiness
Connect the intended harvested organ to observed maturity, condition and the consequences of removing it.
- Is this plant being retained for leaves, mature seed, propagation material or observation? definition
- Which observed leaf condition or pod and seed maturity indicators satisfy the selected harvest criterion? measurement
- Would the proposed leaf or shoot removal conflict with retaining this plant for seed production or identification? action
Seed continuity and propagation The relationship between fenugreek parent material, stored seed and resulting seedlings.
Seeds require both identity continuity and demonstrated propagation performance; neither follows from a fenugreek label alone.
Accession and harvest lineage
Origin and mixing history of seed intended to represent this species or a named cultivar.
Traceable seed origin
Preserve the distinction between supported species identity, claimed cultivar identity and unknown or mixed parentage.
- Which source seed, parent plants, accession or cultivar claim does this harvest descend from? provenance
- Were separately identified plants or harvests mixed, and what identity resolution remains justified? boundary
Stored seed performance
Observed seed integrity and measured germination after handling and storage.
Propagation readiness
Connect storage and treatment history to a dated germination assessment without inferring viability from colour or smell.
- What drying, storage, heat exposure or other treatment has this seed undergone? provenance
- What proportion germinated and produced normal seedlings under the recorded test conditions? measurement
- Does the evidence support sowing, retesting or excluding this material from propagation? action
Harvested material and use Condition and proposed destination of identifiable fenugreek leaves, pods and seeds.
Leaf food, seed food, sprouting and medicinal processing require different evidence; species identification cannot settle their suitability.
Part-specific material condition
Condition observations interpreted for the actual harvested organ and treatment history.
Material condition evidence
Record leaf deterioration, seed moisture, damage and foreign material using an explicit sampling basis.
- Is the material fresh leaf, dried leaf, intact pod or separated seed, and what processing has occurred? definition
- What deterioration, insect damage, visible mould or foreign material was observed, and in what fraction of the sample? measurement
- Which intended-use specification determines whether drying, testing or isolation is appropriate? action
Intended-use assessment
Link botanical material to the evidence required for its proposed destination.
Use-specific decision boundary
Record intended use and assessment status separately from identity. Fenugreek safety guidance distinguishes food amounts from larger exposures and notes allergy and pregnancy concerns. [NCCIH](https://www.nccih.nih.gov/health/fenugreek)
- Is the proposed destination sowing, culinary use, sprouting, feed, medicinal processing or research? definition
- Which external assessment addresses the actual plant part, preparation, exposure and intended recipient? boundary
- What unresolved identity, contamination or use-specific assessment prevents a suitability decision? action
Evidence and external alignment What the world already says about this thing, gathered so the model can be checked against it.
A model that cannot be lined up against existing standards, identifiers and practice cannot be adopted by anyone who already uses them.

Failure modes and hazards
Reported by the breadth pass; each item needs checking against its source before it becomes normative.
- Allergen: seed protein can cause IgE-mediated allergy and occupational asthma in spice workers; cross-reactivity with peanut and other legumes is documented
- Maple-syrup odour of sweat, urine and breast milk after ingestion - a nuisance and a diagnostic confounder for maple-syrup urine disease in neonates of mothers taking fenugreek
- Hypoglycaemia when seed or extract is stacked with antidiabetic drugs; also possible potentiation of anticoagulants (coumarin content is modest but clinically discussed)
- Uterine stimulant / traditional emmenagogue use - pregnancy caution in pharmacopoeial and EMA texts; high-dose late-pregnancy use is a recognised risk discussion, not a settled teratogen
- Adulteration of ground seed with cheaper legumes, cereals or dyes; kasuri methi lots mixed with T. corniculata or other Trigonella
- 2011 German/French EHEC (E. coli O104:H4) outbreak epidemiologically linked to fenugreek sprouting seed imported from Egypt - sprouting seed is a high-risk ready-to-eat vector for enteric pathogens
- Bitter, astringent off-flavour and hard seed coat if under-roasted or poorly debittered flour is used in food
- Lodging, powdery mildew and Fusarium wilt in dense irrigated stands; hardseededness reducing field emergence

Regional variation
Reported by the breadth pass; each item needs checking against its source before it becomes normative.
- India/Pakistan/Bangladesh: methi (seed) and methi saag / kasuri methi (leaf); major commercial production in Rajasthan, Gujarat, Madhya Pradesh; culinary default is the spice seed and dried leaf
- Ethiopia and Eritrea: abish; seed is a berbere constituent and a household spice, also a forage
- Arabic-speaking Near East and North Africa: hulba / helba / hilbeh - seed paste as a condiment (Yemeni hilbeh, Egyptian fenugreek breads) and a postnatal galactagogue
- Iran: shanbalileh - fresh leaves in ghormeh and kuku; seed less dominant than leaf
- Mediterranean / Balkans: historically 'Greek hay' (foenum-graecum) as forage and veterinary galactagogue more than as a table spice
- Alpine Europe: 'fenugreek' in cheese (e.g. Schabziger) is usually Trigonella caerulea (blue fenugreek), not T. foenum-graecum - a naming trap in German, French and Italian trade
- China: hu lu ba (葫芦巴) as a traditional Chinese medicine seed more than a kitchen spice
- North America / EU retail: sold as a spice and as a lactation dietary supplement; food-safety focus is on sprouting seed after the 2011 outbreak

Neighbouring kinds and how to tell them apart
Reported by the breadth pass; each item needs checking against its source before it becomes normative.
- Trigonella caerulea (blue fenugreek, Schabzigerklee) - Different species used as a cheese/herb in the Alps; flowers blue rather than pale yellow/white, seed smaller and less rhomboid; sotolon profile differs. Do not treat Alpine 'fenugreek' cheese herb as T. foenum-graecum without a botanical voucher or ITS/barcode.
- Trigonella corniculata (and some 'kasuri methi' lots) - Often the true source of fine dried-leaf kasuri methi; pods horned (corniculate) rather than the straight to slightly curved beak of T. foenum-graecum; confirm on fruit shape or a named cultivar, not on the trade name 'kasuri'.
- Melilotus spp. (sweet clover) and Medicago spp. (medics) - Same family, trifoliolate leaves; Melilotus has a strong coumarin (new-mown-hay) odour and elongated racemes; fenugreek has a characteristic bitter-maple seed odour (sotolon) and beaked pods. TLC/GC of sotolon vs coumarin separates processed herb.
- Trigonella hamosa and other wild Trigonella - Wild relatives with hooked pods and smaller seed; not the cultivated spice chemotype. Separate by pod curvature, seed size and, if needed, a checklist determination against Kew/POWO.
- Maple flavouring / sotolon-containing foods (and maple-syrup urine disease) - The same odour molecule (3-hydroxy-4,5-dimethylfuran-2(5H)-one) is not unique to fenugreek; dietary history plus, in neonates, amino-acid screening distinguishes fenugreek ingestion from MSUD.
- Other galactagogue herbs (fennel, blessed thistle, goat's rue / Galega) - Goat's rue is Galega officinalis (also Fabaceae) and is a different toxicological profile (galegine); fennel is Apiaceae seed. Label Latin binomial and fruit morphology separate them in mixed lactation teas.
