Enable an agent to recognise a botanical seed cone, assess its development and seed-retention state, and choose appropriate observation, collection or processing 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 a botanical seed cone, assess its development and seed-retention state, and choose appropriate observation, collection or processing actions.
A cone, interpreted here as a physical object of conical form, has a base and a lateral surface that narrows to an apex, with a circular base in the common circular-cone case.
It can be Compare cone anatomy with taxon-specific identification evidence.; Photograph and measure a cone while recording attachment and opening state.; Monitor development and seed release through repeated observations.; Select collection timing using a supported maturity criterion for the identified taxon.; Assess and, where appropriate, extract retained seeds under a documented protocol.; Preserve a reference cone and link it to its parent plant and any extracted seed lot..
Distinguishing features
Establish botanical origin and reproductive anatomy; a tapered silhouette alone does not identify a seed cone.
Distinguish seed-bearing structures from pollen-bearing structures; both male and female cones occur in conifers. [Kew: monkey puzzle tree](https://www.kew.org/plants/monkey-puzzle-tree).
Do not require woody overlapping scales: juniper's berry-like structures are fleshy female cones. [Kew: What is a seed?](https://www.kew.org/read-and-watch/what-is-a-seed).
Allow reduced architecture: some conifers have seed cones reduced to a single seed and associated supporting structures. [Kew: Podocarpaceae](https://powo.science.kew.org/taxon/urn%3Alsid%3Aipni.org%3Anames%3A77126768-1/general-information).
Distinguish a retained cone from retained seed: white spruce cones can remain attached after most seeds disperse. [US Forest Service: white spruce](https://research.fs.usda.gov/silvics/white-spruce).

Bundle to layer to finding to question, as the second pass will find it: 6 bundles · 11 layers · 15 findings · 26 questions.
Botanical identity Establish that the object is a seed cone and determine its botanical context.
The name cone spans unrelated objects, and seed cones must also be distinguished from neighbouring plant organs.
Organ boundary
Determine reproductive identity from anatomy and plant context.
Seed-cone identification
Record the evidence supporting seed-cone identity rather than classification by external shape.
- Which visible or dissected structures support identification as a seed cone? definition
- What excludes a pollen cone, cone-like fruit cluster or vegetative bud? boundary
Parent association
Connect cone identification to a documented taxon and parent plant.
Taxon and parent evidence
Keep direct attachment, collection records and inferred association distinguishable.
- Which taxon identification is supported by the cone and associated plant material? definition
- Was attachment to the recorded parent observed, or was origin inferred after the cone fell? provenance
Cone architecture Describe the arrangement and dimensions of the cone's reproductive structures.
Anatomical variation determines recognition and how the cone can be examined or processed.
Scale and axis structure
Capture structural organisation without requiring a conventional pinecone form.
Structural components
Record identifiable axis, scales, bracts and seed-bearing positions, including reduced or fused structures.
- Which axis, scale, bract and seed-bearing structures can be distinguished? definition
- Are apparently missing structures absent by architecture, obscured, or lost through damage? boundary
Dimensions and form
Make cone measurements comparable across specimens and observation states.
State-qualified dimensions
Associate measurements with scale position, completeness and hydration observations.
- What are axial length and maximum width in millimetres, and how were their endpoints chosen? measurement
- Was the cone closed, open, incomplete, fresh or dried when measured? measurement
Development and seed status Separate cone development from seed presence and seed quality.
A mature-looking cone does not by itself establish that recoverable, viable seeds remain.
Maturity assessment
Interpret maturity through criteria supported for the identified taxon.
Supported maturity criterion
Record the criterion and its applicability instead of assigning universal maturity thresholds.
- Which taxon-specific observations or tests support the assigned developmental stage? measurement
- What source supports using those criteria for this taxon and collection context? provenance
Retained seed assessment
Determine what reproductive material remains and how directly it was assessed.
Seed presence and quality
Keep retained seed count, apparent filling and tested viability as distinct observations.
- How many seeds remain, and was this determined by full extraction, imaging or sampling? measurement
- Is any seed-quality judgment supported by a test, or only inferred from appearance? boundary
Opening and dispersal Track how the cone retains and releases seeds.
Release behaviour governs when seeds remain accessible and whether an intact cone persists.
Release behaviour
Document observed release processes and environmental associations.
Release mechanism evidence
Distinguish scale opening, structural disintegration and other observed routes of seed release.
- Does this cone release seeds through scale separation, disintegration or another observed process? definition
- Which moisture, temperature or handling changes preceded release, and was causation tested? provenance
Retention monitoring
Track attachment and remaining contents separately.
Attachment versus seed retention
Record whether the cone persists on the plant independently of whether seeds remain inside.
- Is the cone attached, fallen intact, or represented by a persistent axis and fragments? measurement
- What observation would establish that the collection window is closing or has passed? action
Condition and collection Relate cone damage and handling history to collection and processing choices.
The same cone may be suitable as a reference specimen but unsuitable for useful seed recovery.
Damage assessment
Locate damage in the cone and establish its implications without assuming a cause.
Damage to reproductive structures
Record affected scales, axis and seed-bearing positions, with evidence for any attributed damage agent.
- Which structures show feeding, breakage, decay or abnormal development, and how extensive is it? measurement
- Does the observed damage prevent identification, reduce recoverable seeds, or require further examination? action
Collection and processing choice
Choose a treatment matched to cone identity, maturity and intended use.
Documented cone treatment
Specify whether to monitor, collect, preserve or process the cone, retaining links to resulting seed material.
- Should this cone remain for monitoring, become a reference specimen, or enter seed extraction? action
- Which taxon-specific protocol supports the proposed drying, storage or extraction treatment? provenance
- How will treatment history and extracted seeds remain linked to the cone and its parent 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.

What the second pass must settle
- Does the registry intend only seed cones, as Q22710's description states, or the broader botanical usage that also includes pollen cones?
- Does the intended taxonomic scope include cones of non-conifer gymnosperms, and which reduced reproductive structures qualify?
- Which taxon-specific anatomical references and maturity criteria should govern identification and collection decisions?
- Which taxa require special treatment of persistent closure, fleshy structures or cone disintegration during seed recovery?
- Does an existing Vercy world model already own this botanical concept, requiring a registry link rather than a separate publication?
