Enable an agent to recognise Coriandrum sativum, assess its condition and developmental stage, and choose justified cultivation, harvest, propagation or material-handling actions.
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. Unreviewed either way.

Purpose and description
Enable an agent to recognise Coriandrum sativum, assess its condition and developmental stage, and choose justified cultivation, harvest, propagation or material-handling actions.
It can be Identify a specimen or retain an unresolved determination and request the missing diagnostic evidence.; Sow a traceable propagule lot and assess emergence using a defined counting unit.; Adjust cultivation using observed plant response and locally supported guidance.; Select leaf harvesting or continued reproductive growth according to the intended output.; Collect and separate fruits by maturity, retaining source and handling history.; Route harvested organs to storage, further assessment or processing according to documented condition and intended use..
Distinguishing features
Inspect leaves at multiple stem positions: broad, toothed or incised lower divisions and finely divided upper leaves provide a stronger identification test than one parsley-like leaf. [Flora of China](https://www.iplant.cn/foc/pdf/Apiaceae.pdf)
Inspect flowers where available: compound umbels with white or rose-pink petals and enlarged outer petals contribute to separating candidates with similar foliage. [Flora of China](https://www.iplant.cn/foc/pdf/Apiaceae.pdf)
Inspect mature fruits: a globose, hard fruit with evident fine ribs that does not readily separate at maturity is a stronger discriminator than the culinary label 'seed'. [Flora of China](https://www.iplant.cn/foc/pdf/Apiaceae.pdf)
Resolve 'cilantro' or 'coriander' through a scientific determination and specimen or lot provenance; a common name alone does not establish membership in the accepted species Coriandrum sativum L. [Kew Plants of the World Online](https://powo.science.kew.org/taxon/840760-1)

- Clinical efficacy, patient-specific allergy assessment and medical treatment.
- Commercial contracts, certification schemes and jurisdiction-specific food compliance.
Characteristics
- Identification support
- label-only; morphology-supported; expert-determined; conflicting; unresolved Determines whether species-specific actions are justified.
- Cultivar or accession origin
- Named cultivar, accession, supplier lot or parent population, with evidence or unknown Supports interpretation of growth and harvest differences without assuming cultivar traits.
- Organ and material form
- Whole living plant; cut shoot; leaf; root; flower; immature fruit; mature fruit; separated mericarp; botanical seed; mixed or unresolved Prevents leaf quality, spice maturity and propagation assessments from being conflated.
- Developmental stage
- Germinating; seedling; vegetative; bolting; flowering; fruit developing; fruit mature; senescent; dead; mixed Connects the observed plant to available leaf-harvest and reproductive actions.
- Leaf form by position
- Lower, middle or upper position; observed division pattern; photograph or specimen reference Makes identification sensitive to developmental variation.
- Bolting onset
- Days from documented emergence to a stated bolting criterion; observation interval Allows local comparison of the useful leaf-production period.
- Harvestable foliage
- Grams fresh mass per plant or defined area, with sampling and quality criteria Supports harvest decisions using usable foliage rather than plant height alone.
- Organ condition
- Observed turgor, discoloration, lesions, feeding damage, decay and affected proportion by organ Separates visible symptoms from an unconfirmed cause.
- Fruit maturation
- Observed colour, firmness, attachment and within-sample maturity distribution Supports choosing when to collect fruit and which maturity classes to separate.
- Propagule germination
- Percent germinated, denominator, propagule unit, test conditions and elapsed days Prevents a spice label or fruit appearance from being treated as proof of planting performance.
- Postharvest exposure
- Hours since harvest; temperature history in degrees Celsius; moisture result with method and basis where relevant Provides evidence for condition assessment of fresh foliage and dry fruits.

Bundle to layer to finding to question, as the second pass will find it: 5 bundles · 10 layers · 10 findings · 20 questions.
Coriander identity Establish what supports identifying the observed material as Coriandrum sativum.
Common names and detached foliage can conceal species uncertainty.
Taxon and origin
Connect the determination to the registered species and its evidence.
Supported species determination
Record the identification basis separately from a supplier name or culinary label.
- What determination connects this specimen or lot to Coriandrum sativum? definition
- Which observer, voucher, supplier record or diagnostic examination supports that determination? provenance
Diagnostic organ combination
Evaluate the organs actually available for recognition.
Recognition with incomplete material
Retain missing and conflicting characters instead of upgrading a partial match into certainty.
- What leaf-position, flower and fruit observations support or contradict the identification? measurement
- Which plausible lookalike remains unresolved, and what additional organ or examination would distinguish it? boundary
Organs and use target Distinguish the biological material from the output sought.
Leaf herbs, spice fruits and planting material require different judgments within the same species.
Organ resolution
Describe material precisely enough to interpret observations.
Culinary seed versus botanical unit
The spice is the fruit; record whether material labelled seed is whole fruit, a separated component or unresolved material. [Flora of China](https://www.iplant.cn/foc/pdf/Apiaceae.pdf)
- Which organ and physical unit does this material actually contain? definition
- Are counts and measurements based on whole fruits, mericarps, botanical seeds or mass? measurement
Production intent
Make the desired output explicit before evaluating suitability.
Leaf or reproductive output
Record whether the present objective is foliage, roots, spice fruit, planting material or another specified output.
- Which organ and quality attributes define success for this specimen or stand? definition
- Would the proposed harvest prevent the intended later reproductive or root harvest? action
Growth and bolting Track the transition from foliage production to reproduction.
The same developmental change has different consequences for leaf production and fruit production.
Developmental observations
Anchor stage assignments in dated observations.
Observed reproductive transition
Record bolting, flowering and fruit development independently of calendar-based predictions.
- Which observed stem, bud, flower or fruit features establish the present stage? measurement
- When did each transition occur relative to sowing or emergence, and what proportion of the stand has transitioned? measurement
Environment and harvest window
Connect local growing conditions to the intended harvest.
Bolting response and next action
Hot, humid weather can promote bolting; local stage observations should guide leaf-harvest or fruit-production decisions. [University of Maryland Extension](https://extension.umd.edu/resource/cilantrocoriander)
- What temperature, light, moisture and cultivar evidence accompanies the observed bolting response? provenance
- Does the current objective support harvesting foliage now, establishing a replacement sowing or allowing flowering? action
Plant condition and harvest Assess living coriander by affected organs and the consequences of removal.
A usable leaf harvest and a plant capable of completing fruit production are different outcomes.
Foliage and root condition
Record symptoms relevant to continued growth and the target organ.
Symptoms without assumed diagnosis
Document wilting, discoloration, lesions or damage with stage and exposure history; keep proposed causes provisional.
- Which leaves, stems or roots are affected, how severely, and how has the condition changed? measurement
- What evidence distinguishes developmental change from water stress, injury or a confirmed pest or disease? boundary
Organ removal and recovery
Evaluate harvesting against remaining growth and reproductive capacity.
Harvest consequence
Record what a cut or whole-plant harvest removes and verify subsequent growth rather than assuming a repeat yield.
- How much foliage, which growing points and whether the root system would remain after harvest? measurement
- Does observed recovery from previous cuts support another foliage harvest or continuation to fruit? action
Fruit, propagation and postharvest Assess mature reproductive material and detached organs for their next use.
Fruit maturity, germination performance and harvested-material condition are distinct forms of readiness.
Fruit readiness and germination
Separate collection decisions from evidence of planting performance.
Maturity is not viability
Record maturity observations, processing history and germination results separately.
- What maturity observations and within-lot variation support fruit collection now? measurement
- What germination test and treatment history support using this lot for sowing? provenance
Detached-organ disposition
Connect harvested foliage or fruit to condition evidence and handling requirements.
Use-specific material assessment
Assess fresh foliage and dry fruit under separate criteria, linking processing or food-safety decisions to the responsible neighbouring model.
- What harvest time, handling history and observed deterioration are documented for this organ lot? provenance
- Which evidence supports storage, further testing, processing or rejection for the stated use? action
What the second pass must settle
- Which regional diagnostic key and minimum character set reliably separate sterile or detached Coriandrum sativum from parsley and other locally plausible lookalikes?
- Which cultivar-specific temperature and photoperiod responses predict bolting under the intended growing conditions?
- What harvest intensity and interval preserve useful regrowth for the selected cultivar and production system?
- Which fruit maturity criteria and germination protocols are validated for whole fruits versus separated propagule units?
- What organ-specific storage conditions, quality limits and testing requirements are validated for the intended fresh-herb, spice or propagation use?
