Purpose and description
Enable an agent to recognise Citrus × aurantiifolia, assess a plant or accession attributed to it, and choose cultivation, propagation or harvest actions supported by identification and condition evidence.
Citrus × aurantiifolia is a cultivated evergreen citrus hybrid in the family Rutaceae, derived from citron and Citrus micrantha ancestry and grown for its small, acidic fruits commonly called Key or Mexican limes.
It can be Compare a labelled lime plant with authenticated references and record a provisional or supported identification.; Select and trace candidate propagation material after checking scion identity, provenance and health evidence.; Adjust watering, drainage, nutrition or exposure protection using measured conditions and plant responses.; Inspect symptomatic tissues and request targeted diagnostic testing before assigning a cause.; Assess fruit cohorts for harvest against recorded culinary or processing requirements..
Distinguishing features
Check whether an authoritative identification supports Citrus × aurantiifolia; a label saying only 'lime' does not distinguish it from other lime taxa.
Compare mature fruit size, shape, rind thickness and seed count against authenticated Citrus × aurantiifolia and Persian lime references; use a combination of characters rather than a single fruit.
Examine petiole wings and leaf form against authenticated references to separate it from makrut lime and other citrus with more conspicuously winged petioles.
Combine shoot thorniness, leaf measurements, flower characters and fruit characters; juvenile growth or a thornless selection can make a single-character identification unreliable.
Trace the sampled shoot to its position above or below any graft union so rootstock leaves or fruit are not used to identify the Citrus × aurantiifolia scion.

- Other citrus taxa marketed as limes, including Persian lime and makrut lime
- Independent taxonomic models for rootstock species
- Orchard business operations, land ownership and irrigation equipment
- Postharvest fruit lots, juice processing and essential-oil products
- Standalone models of citrus pathogens, pests and plant-protection products
Characteristics
- Taxonomic identification
- confirmed against a cited reference | provisional | conflicting | unidentified Controls whether taxon-specific conclusions and propagation decisions are justified.
- Accession and cultivar attribution
- Linked accession, cultivar designation, supplier and supporting record Separates within-taxon variation from misidentification and preserves propagation provenance.
- Scion-rootstock configuration
- own-rooted | grafted with identified rootstock | grafted with unknown rootstock | unknown Changes interpretation of vigour, stress responses and shoots suitable for propagation.
- Leaf and petiole dimensions
- Leaf blade length and width, petiole length and wing width in mm; sampled shoot position Provides comparable identification evidence while exposing variation between scion and rootstock growth.
- Shoot thorniness
- Thorns per sampled shoot length and thorn length in mm, with shoot age Supports identification and handling decisions without treating thornlessness as automatic exclusion.
- Fruit diagnostic profile
- Longitudinal and equatorial diameter in mm, mass in g, rind thickness in mm and seeds per fruit Helps compare the accession with other lime taxa and evaluate fruit development.
- Phenological state
- vegetative flush | flowering | fruit set | fruit enlargement | harvestable fruit; multiple states may coexist Makes observations and cultivation actions specific to the organs currently developing.
- Root-zone conditions
- Substrate pH, electrical conductivity in dS/m with method, and moisture or water potential with method Supports investigation of water, drainage, salinity and nutrient problems.
- Temperature exposure
- Minimum and maximum temperature in °C, exposure duration in hours and measurement location Connects observed damage and growth interruption to actual exposure rather than a regional climate label.
- Health evidence
- no symptoms observed | symptoms recorded | diagnostic result available | cause unresolved Separates visual observations from confirmed causes when choosing treatment or propagation material.
- Fruit maturity and juice profile
- Rind colour by stated scale, juice yield by stated basis, soluble solids in °Brix and titratable acidity by stated method Allows harvest decisions to reflect intended use rather than rind colour alone.

Drafted structure
Bundle to layer to finding to question, as the second pass will find it: 6 bundles · 11 layers · 17 findings · 27 questions.
Lime identity and provenance Establishes what the registered name covers and whether a particular plant belongs to it.
Common lime names, horticultural labels and grafted plants can conceal different biological identities.
Taxon boundary
Connects the registry name to an explicit taxonomic interpretation.
Name and reference alignment
Record the authority and evidence used to interpret Citrus × aurantiifolia without assuming every commercial lime name is equivalent.
- Which taxonomic reference defines Citrus × aurantiifolia for this model, and which spelling variants or synonyms does it recognise? definition
- Which evidence separates this accession from Persian lime and other plants sold under the same local lime name? boundary
Accession history
Tracks the horticultural identity and physical origin of the plant being assessed.
Propagule and graft origin
Keep cultivar attribution, propagation source and rootstock identity distinct from the taxon name.
- Where did the seed, cutting or budwood originate, and what supports its cultivar or accession label? provenance
- Is the observed shoot part of the attributed scion, an own-rooted plant or growth from below a graft union? boundary
Diagnostic lime characters Organises comparable evidence from shoots, leaves, flowers and fruit.
Identification requires a character combination that accounts for developmental and horticultural variation.
Vegetative characters
Examines leaves, petioles and thorns on traceable shoots.
Leaf, petiole and thorn profile
Record measurements and images with shoot maturity and graft position so unlike tissues are not compared.
- What are the leaf dimensions, petiole-wing dimensions and thorn lengths on representative mature scion shoots? measurement
- Do discrepancies from authenticated reference material reflect juvenile growth, cultivar variation, rootstock growth or unresolved identity? boundary
Flowers and fruit
Adds reproductive characters when vegetative evidence is insufficient.
Reproductive identification profile
Compare flowers and multiple developmentally comparable fruit with authenticated material.
- What flower characters, fruit dimensions, rind thicknesses and seed counts are documented for the sampled plant? measurement
- Does the combined reproductive profile support Citrus × aurantiifolia over Persian lime, or is specialist identification still needed? boundary
Growth and fruiting cycle Tracks vegetative flushes, flowering and identifiable fruit cohorts.
A tree can carry organs at different stages, so a single whole-tree maturity label is insufficient for care or harvest.
Flush and flowering
Relates shoot development and flowering to observed local conditions.
Seasonal development record
Record actual flush and flowering events rather than assigning a universal citrus calendar.
- When do vegetative flushes and flowering occur at this site, and how much of the canopy is involved? measurement
- Which local observations support the timing of pruning or other interventions around flowering and new growth? action
Fruit cohort development
Follows fruit from set through retention, enlargement and harvest assessment.
Fruit set and retention
Associate changes in fruit number and size with a defined flowering cohort and management history.
- How many fruit persist from a recorded flowering cohort, and how do their dimensions change over time? measurement
- What observations distinguish expected fruit shedding from a loss event requiring investigation? action
Cultivation and plant health Connects exposure, root-zone conditions and symptoms to evidence-based care.
Lime scions, rootstocks and growing conditions must be considered together when interpreting poor growth or damage.
Exposure and root zone
Records temperature, water conditions and substrate evidence relevant to the actual planting configuration.
Site fit and stress response
Assess site suitability using measured exposures and responses of the identified scion-rootstock combination.
- What temperature extremes, drainage conditions, moisture readings and salinity measurements coincide with growth interruption or damage? measurement
- Which watering, drainage or exposure-protection change is supported for this plant and rootstock by the available evidence? action
Symptoms and diagnosis
Separates visible damage from confirmed pest, pathogen or physiological causes.
Diagnostic and propagation status
Link symptoms and laboratory results to sampled tissues and use them to assess candidate propagation material.
- Which scion or rootstock tissues show symptoms, and what dated diagnostic evidence supports the suspected cause? provenance
- What inspection or testing remains necessary before this plant supplies budwood, cuttings or other propagation material? action
Harvest and use readiness Evaluates fruit on the plant against a stated intended use.
Harvest readiness depends on internal fruit properties and use requirements as well as visible rind condition.
Fruit quality assessment
Measures a representative fruit sample from a defined cohort.
Juice and rind readiness
Keep juice yield, acidity, soluble solids and rind observations associated with their sampling and measurement methods.
- What juice yield, titratable acidity, soluble solids and rind condition does the sampled fruit cohort exhibit? measurement
- Which documented requirements define readiness for the intended fresh-fruit, juice or rind use? definition
Harvest decision and handoff
Turns readiness evidence into a harvest decision and preserves origin when fruit becomes a separate lot.
Cohort selection and traceability
Identify which fruit to pick and transfer plant identity and relevant treatment history to the harvested-lot record.
- Which fruit should be harvested or left to develop, based on sampled quality and the stated use? action
- Which accession, harvest date and relevant treatment records must accompany the fruit when responsibility passes to a postharvest model? boundary
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.
