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 Gentiana plants, record identification confidence and condition, and judge suitable observation, cultivation or conservation actions.
Gentiana is a genus of herbaceous flowering plants in the family Gentianaceae, including annual and perennial species, many distinguished by conspicuous tubular or funnel-shaped flowers.
It can be Guide non-destructive photography and measurement for botanical identification.; Compare a determination with a regional key and flag unresolved alternatives.; Track flowering, fruiting and population observations across dated visits.; Assess cultivation conditions against evidence for the identified species or accession.; Plan documented propagation trials with taxon-specific treatments.; Check identification, conservation constraints and permissions before collection or movement..
Distinguishing features
Interpret Gentiana as a botanical genus name; the common name gentian alone does not establish membership.
Require identification against a relevant botanical key using a combination of leaf, calyx, corolla and reproductive characters rather than flower colour alone.
Examine corolla folds or appendages between lobes where the applicable key uses them to distinguish Gentiana from Gentianella or Gentianopsis.
Check accepted names and synonyms before treating historically labelled gentians as members of Gentiana.
Separate a verified genus assignment from a species determination: evidence sufficient for Gentiana may be insufficient for a species or hybrid name.

Characteristics
- Taxonomic determination
- Assigned taxon linked to a taxonomic reference, determiner and determination date Names and genus boundaries depend on the reference used.
- Identification confidence
- Unassessed; tentative genus; verified genus; tentative species; verified species Prevents uncertain identification from supporting species-specific actions.
- Corolla and calyx characters
- Observed shape, lobe counts, interlobular structures, colour and calyx form; unknown when not visible Reproductive structures provide evidence for distinguishing related gentians.
- Plant and flower dimensions
- Plant height in cm; leaf, calyx and corolla dimensions in mm, with developmental stage Measurements support comparisons with identification keys.
- Root-zone conditions
- Substrate pH, moisture measurement with method, and temperature in °C Suitability must be assessed for the identified taxon rather than assumed for the genus.
- Phenological stage
- Vegetative; budding; flowering; fruiting; seed release; senescent; dormant; uncertain Determines which identification, monitoring and propagation actions are timely.
- Origin and establishment
- Wild origin documented; cultivated origin documented; uncertain origin; establishment status separately recorded Distinguishes occurrence evidence from horticultural presence.
- Collection constraints
- Links to applicable taxon, locality, land-access and collection requirements Determines whether sampling, seed collection or removal is permissible.

Drafted structure
Bundle to layer to finding to question, as the second pass will find it: 5 bundles · 9 layers · 16 findings · 28 questions.
Gentiana identity Establish what Gentiana denotes and whether the observed plant belongs to it.
Common names, historical classifications and incomplete specimens can produce misleading assignments.
Taxonomic circumscription
Anchor genus membership and names to an explicit taxonomic treatment.
Accepted name and membership
Record a supported determination while retaining the original label and unresolved alternatives.
- Which taxonomic treatment defines Gentiana and accepts the assigned name? provenance
- Does the recorded name currently belong to Gentiana under that treatment, or to a neighbouring genus? boundary
Diagnostic evidence
Connect genus and species determinations to observable botanical characters.
Gentian character combination
Use the applicable key to specify which vegetative and reproductive observations distinguish candidate taxa.
- Which leaf, calyx, corolla-lobe and interlobular characters does the relevant key require? definition
- Which required structures have been photographed or measured, and which remain unavailable? measurement
- What evidence excludes Gentianella, Gentianopsis or other locally plausible alternatives? boundary
Habitat and origin Describe the environmental setting and provenance of the plant or population.
A genus-level label cannot establish native occurrence or a single preferred growing environment.
Occurrence provenance
Distinguish documented wild occurrences from planted or uncertain records.
Locality and establishment
Retain evidence connecting the determination to a locality and origin.
- What dated observation, voucher or accession record supports this Gentiana occurrence? provenance
- Is the plant wild, planted or of uncertain origin, and what evidence supports its local establishment status? boundary
Microhabitat fit
Record local conditions without assigning one habitat preference to all Gentiana.
Substrate, water and exposure
Compare observed root-zone and exposure conditions with evidence for the identified taxon.
- What substrate pH, moisture regime, drainage, elevation and light exposure were observed? measurement
- Which documented requirements of this species or accession support keeping or changing those conditions? action
Seasonal life and reproduction Track development, reproductive outcomes and propagation evidence.
Flower availability affects identification, while seed maturity and germination requirements affect propagation.
Phenology and fruiting
Link seasonal observations to flowering and reproductive outcomes.
Flower-to-seed observations
Record reproductive stages without treating flowering as proof of viable seed production.
- On which dates were buds, open flowers, developing fruits and seed release observed? measurement
- What observations distinguish flower production, fruit formation and viable seed production in this plant? measurement
Propagation evidence
Keep propagation methods specific to an identified taxon and documented material.
Seed and vegetative protocols
Record seed handling and any supported vegetative methods as traceable protocols.
- Which source supports the proposed seed storage, pretreatment and germination conditions for this Gentiana taxon? provenance
- What germination or establishment outcomes were measured, with treatment, duration and sample size? measurement
- Is vegetative propagation supported for this taxon and material, and under what conditions? action
Condition and stewardship Support care, monitoring and collection decisions grounded in plant condition and locality.
Gentiana care and conservation decisions require species-level evidence, seasonal context and collection constraints.
Plant condition
Assess observed symptoms against expected development and growing conditions.
Decline or seasonal change
Separate observations of damage or decline from interpretations such as dormancy or disease.
- What changes in foliage, growth, flowering or visible root condition have occurred since the previous observation? measurement
- What taxon-specific evidence distinguishes expected senescence or dormancy from harmful stress? boundary
- Which care adjustment or diagnostic observation is justified by the recorded symptoms and conditions? action
Population and collection
Connect monitoring and material collection to conservation evidence and permissions.
Collection decision
Evaluate proposed sampling, seed collection or removal for the identified taxon and site.
- Which current conservation assessment and collection requirements apply to this taxon at this locality? provenance
- Do population observations, intended collection amount and permissions support the proposed action? action
- Can photographs, measurements or existing voucher material answer the identification question without removing a plant? 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.
