Purpose and description
Enable an agent to identify Apium graveolens, assess documented plants and populations, and choose evidence-supported cultivation, monitoring or conservation actions.
Apium graveolens L. is a species of aromatic herbaceous plant in the family Apiaceae, usually biennial, that includes cultivated celery, celeriac and leaf celery.
It can be Resolve a specimen or accession to the species and retain identification uncertainty.; Associate celery and celeriac accessions with their documented cultivated form.; Track bolting, flowering and fruit maturation to support a stated cultivation or seed-production objective.; Compare observed site conditions and plant symptoms before selecting a cultivation adjustment.; Monitor wild or escaped populations for recruitment, persistence and habitat change.; Refer uncertain identification or insufficient conservation evidence for specialist review before collection or removal..
Distinguishing features
Resolve the full binomial Apium graveolens L.; the epithet graveolens alone does not distinguish it from Anethum graveolens. The accepted name dates to 1753. [Kew POWO](https://powo.science.kew.org/taxon/urn%3Alsid%3Aipni.org%3Anames%3A838067-1)
Check pinnately compound leaves, grooved petioles and small white flowers in compound umbels together; these support identification but require a regional key to exclude related Apiaceae. [Naturalis](https://useful-plants.linnaeus.naturalis.nl/linnaeus_ng/app/views/species/taxon.php?epi=202&id=127885)
Where mature fruit is available, compare its broadly ovoid outline and approximately 1.5 mm length with a botanical description rather than relying on culinary smell. [Kew botanical description](https://powo.science.kew.org/taxon/urn%3Alsid%3Aipni.org%3Anames%3A838067-1/general-information)
Distinguish petiole-selected celery from celeriac within the species; cultivated organ enlargement does not by itself establish a separate species. [NC State Extension](https://plants.ces.ncsu.edu/plants/apium-graveolens/)
Distinguish an identified living plant or population from a detached bunch, storage organ or packet labelled celery, whose species attribution needs its own provenance.

Characteristics
- Taxonomic identity
- Apium graveolens L., 1753; species; Apiaceae Anchors recognition to a botanical taxon rather than a market name. [Kew POWO](https://powo.science.kew.org/taxon/urn%3Alsid%3Aipni.org%3Anames%3A838067-1)
- External taxonomy mapping
- NCBI Taxonomy 4045; GBIF identifier with checklist, version and retrieval date Connects sequence and occurrence evidence while preserving the taxonomic source used. [NCBI Taxonomy](https://www.ncbi.nlm.nih.gov/Taxonomy/Browser/wwwtax.cgi?id=4045&mode=Info)
- Biological record level
- species concept | population | individual | accession | observation Prevents a species assessment from being assigned to an individual plant or seed accession.
- Cultivated form and accession
- wild or unspecified form; documented celery or celeriac form; other documented selection; cultivar and accession identifiers Makes organ development and cultivation observations interpretable without splitting the registry species.
- Diagnostic organ observations
- leaf division and petiole grooves as descriptors; flower colour; fruit length in mm; dated photographs or voucher Supports auditable identification using several organs instead of a common name.
- Developmental stage
- seed | germinating | seedling | vegetative | bolting | flowering | fruiting | senescent | dead Separates vegetative harvest objectives from reproductive development and seed collection.
- Habitat conditions
- soil moisture with method; electrical conductivity in dS/m with sampling method; temperature in °C; inundation duration in days Allows site suitability and stress hypotheses to be tested against conditions experienced by the recorded plants.
- Occurrence establishment status
- native | introduced | cultivated | escaped | naturalized | uncertain; geographic area and evidence date Separates planted presence from evidence of a self-maintaining population.
- Conservation assessment
- assessment authority, category, geographic scope, assessment year and source; unverified when incomplete Prevents global status, regional rarity and crop abundance from being treated as interchangeable.

Drafted structure
Bundle to layer to finding to question, as the second pass will find it: 5 bundles · 9 layers · 16 findings · 29 questions.
Species identity and recognition Establish which botanical entity the celery name denotes and how an observation supports identification.
Common names, cultivated forms and similar Apiaceae can otherwise produce false species assignments.
Accepted name and crosswalks
Anchor the registry entry to a sourced species concept.
Accepted Apium graveolens concept
Kew accepts Apium graveolens L., first published in 1753; NCBI maps the species to 4045. [Kew POWO](https://powo.science.kew.org/taxon/urn%3Alsid%3Aipni.org%3Anames%3A838067-1), [NCBI Taxonomy](https://www.ncbi.nlm.nih.gov/Taxonomy/Browser/wwwtax.cgi?id=4045&mode=Info)
- Which taxonomic treatment and version define the Apium graveolens concept used here? provenance
- Which GBIF checklist identifier matches this concept, and are alternative identifiers synonyms or dataset-specific records? boundary
Diagnostic evidence
Assess leaf, petiole, flower and fruit evidence against relevant alternatives.
Multi-organ identification
Pinnate leaves, grooved petioles and compound umbels provide a recognition checklist whose diagnostic strength must be tested with a regional flora. [Naturalis](https://useful-plants.linnaeus.naturalis.nl/linnaeus_ng/app/views/species/taxon.php?epi=202&id=127885)
- Which leaf, petiole, flower and mature-fruit characters were actually observed on this plant? measurement
- Which locally occurring Apium, Helosciadium or other similar Apiaceae have been excluded using a botanical key? boundary
- Is the available evidence sufficient for identification, or is a flowering or fruiting voucher needed? action
Cultivated forms and biological units Represent variation within the species while keeping plants, populations and products distinct.
Celery and celeriac differ in selected organs, while observations and decisions apply at different biological levels.
Cultivated form provenance
Record named selections and their evidence without assuming horticultural labels are accepted botanical ranks.
Celery and celeriac assignment
Celery and celeriac are documented cultivated forms associated with Apium graveolens; preserve both the supplied name and the taxonomic interpretation. [NC State Extension](https://plants.ces.ncsu.edu/plants/apium-graveolens/)
- Is the accession documented as petiole celery, celeriac, leaf celery, a wild collection or an unspecified form? definition
- Which supplier record, accession passport or taxonomic treatment supports its cultivar or group name? provenance
Plant, population and product boundaries
Identify the subject to which each observation belongs.
Biological subject and harvest links
A living celery plant, its population and a harvested celery product require separate records connected by provenance.
- Does this observation describe one plant, a field population, a seed accession or the species as a whole? boundary
- If material was harvested, which plant or accession supplied it and which organ was removed? provenance
Development and cultivation state Track development and condition in relation to the intended use of living plants.
Vegetative celery production and reproductive seed production require different interpretations of bolting and maturity.
Phenology and reproduction
Record the observed life cycle rather than infer stage from calendar age.
Vegetative to reproductive transition
Kew describes the species as biennial; actual bolting, flowering and fruiting dates must be recorded for each accession and environment. [Kew POWO](https://powo.science.kew.org/taxon/urn%3Alsid%3Aipni.org%3Anames%3A838067-1)
- When did germination, bolting, flowering and mature fruit first occur for this accession? measurement
- What floral sexual expression and pollinator observations are documented, without assuming separate male and female plants? measurement
- Does the current stage support vegetative harvest, continued growth or collection of mature propagules? action
Organ condition and growing environment
Relate organ development and symptoms to measured growing conditions.
Form-specific condition assessment
Assess petiole, leaf and storage-organ development relative to the documented cultivated form and production objective.
- Which organs show abnormal growth, discoloration, wilting or lesions, and how widespread are those symptoms? measurement
- What moisture, temperature, salinity and management observations support the proposed explanation? provenance
- Which cultivation adjustment is justified by the evidence, and what observation will determine whether it helped? action
Range, populations and conservation Interpret occurrences in their geographic, ecological and assessment context.
A widespread cultivated vegetable can coexist with wild populations whose provenance and conservation needs differ.
Range and establishment
Separate native distribution from cultivation and subsequent establishment.
Geographically qualified occurrence
Kew gives the native range as Macaronesia to North Africa and Europe to the western Himalaya; individual locality status still requires evidence. [Kew POWO](https://powo.science.kew.org/taxon/urn%3Alsid%3Aipni.org%3Anames%3A838067-1)
- Which regional flora or occurrence history supports native, introduced or cultivated status at this locality? provenance
- Are seedlings and repeated generations present independently of planting or discarded cultivated material? measurement
- What substrate moisture, salinity and disturbance characterize the occupied microsite? measurement
Population status and intervention
Connect conservation decisions to dated assessments and local population evidence.
Assessment scope and local condition
Keep conservation category provisional until the original assessment, year and geographic scope are verified; evaluate local recruitment and threats separately.
- What is the original IUCN assessment category and year, and which regional assessments also apply? provenance
- What do repeated counts, recruitment observations and habitat changes show about this wild population? measurement
- Does the evidence support monitoring, seed conservation, habitat management or control of an introduced population? action
