Locule identity Establish which anatomical compartment is being described and how the term is being used.
Organ context
Anchor the compartment to a particular plant organ and specimen.
Enclosing organ and position
Record the specimen, enclosing organ and chamber position before assigning properties to the locule.
- Which specimen and particular ovary, fruit or anther contain this locule? provenance
- Which axis, landmarks and chamber label identify its position within that organ? boundary
Terminology and unit
Specify what the observer treats as one locule.
Counting convention
Preserve the source's anatomical meaning, especially where anther terminology or developmental stage changes the counting unit.
- What anatomical boundary does the source use to define one locule? definition
- For an anther, how does the source distinguish a locule from a pollen sac and a theca? boundary
- Which observed material or anatomical reference supports that interpretation? provenance
Chamber architecture Describe the partitions, connections and geometry that establish the compartment.
Partitions and connectivity
Determine the extent of separation from neighbouring spaces.
Boundary continuity
Document chamber walls and septa across the examined organ extent, separating observed continuity from inferred continuity.
- Which walls or septa delimit the chamber, and over what extent were they examined? boundary
- Do serial sections or volumetric images show connections to neighbouring chambers? measurement
Geometry and enumeration
Measure the individual chamber and situate it within the organ's chamber arrangement.
Locule size and count
Record chamber dimensions and organ-level locule count with their observation plane, stage and counting convention.
- What are the chamber dimensions, units and section orientation, or its reconstructed volume? measurement
- How many distinct locules are supported by the examined organ extent at this stage? measurement
- What additional sections would resolve an uncertain partition or chamber count? action
Contents and attachments Record what occupies the chamber and how reproductive contents relate to its internal anatomy.
Chamber occupancy
Describe visible contents and the limits of detecting them.
Contents observation
Record identified contents, their abundance where measurable, and whether apparent emptiness reflects adequate inspection.
- Which ovules, seeds, pollen or other materials are visible within this locule? measurement
- What count or occupancy estimate is supported, and how much of the chamber was inspected? measurement
- Could sectioning, extraction or limited resolution explain the absence of detected contents? provenance
Placental relationships
For ovary and fruit contexts, relate the compartment to observed reproductive attachment structures.
Ovule attachment map
Record placental position and attachment evidence without deriving carpel number solely from locule count.
- Where are placentae and ovule attachment points relative to the locule's walls and partitions? boundary
- Is the attachment arrangement directly observed, reconstructed from earlier stages or unresolved? provenance
Development and observation Track chamber change and determine whether observed alterations are biological or introduced during examination.
Developmental continuity
Relate locule observations across organ development.
Chamber stage comparison
Separate demonstrated continuity of a chamber from comparisons between different specimens or stages.
- What developmental stage was observed, and how was it established? provenance
- What evidence connects this locule to a chamber observed at an earlier or later stage? provenance
- Have its partitions, connections or contents changed between the compared observations? measurement
Integrity and examination
Assess chamber condition and choose observations that can resolve uncertainty.
Opening or preparation effect
Record openings, collapse and disruption while keeping their proposed causes separate from the visible evidence.
- What evidence distinguishes natural organ opening from a tear, cut or collapse introduced during preparation? provenance
- Which further image, serial section or comparison specimen would clarify the chamber's original boundaries? action
- If destructive examination is proposed, which locule relationships must be documented before cutting? action
Evidence and external alignment What the world already says about this thing, gathered so the model can be checked against it.
Reported evidence
Findings from the breadth pass, kept separate from the structural claims.

What it is Filled
A locule is an internal chamber or compartment in a biological structure, especially an ovule-containing chamber of a plant ovary, a corresponding chamber in a fruit, or a pollen-containing cavity of an anther.
In scope
- Identification of an individual locule within a specified reproductive organ and specimen
- Chamber boundaries, separating septa and connections with adjacent chambers
- Locule dimensions, position and contribution to the enclosing organ's locule count
- Ovules, seeds or pollen associated with the chamber, recorded separately from the chamber itself
- Changes in chamber configuration, occupancy and integrity across development
Out of scope
- Whole-organ models of ovaries, fruits, anthers and flowers
- Carpels, septa, placentae and other tissues as independently modelled anatomical structures
- Ovules, seeds, pollen grains and their intrinsic development or viability
- Plant species taxonomy, population distribution and conservation status
- Nonbotanical uses of locule or loculus pending registry disambiguation
Why it exists Filled
Enable an agent to recognise a locule as a chamber within a plant reproductive organ, record its boundaries and contents, and select observations that resolve its identity and condition.
Distinguishing features Filled
- Identify an internal anatomical compartment of an enclosing organ; an external lobe or surface groove alone does not establish a locule.
- Separate the chamber from its boundary tissues: a septum divides compartments, while the locule is the compartment being divided.
- Distinguish the compartment from its contents; the absence of visible ovules, seeds or pollen does not by itself establish that the chamber is absent.
- Record locule count independently of carpel count; Kew describes orchids with one locule and three parietal placentae, illustrating why internal organisation needs direct evidence. See [Kew's Orchidaceae account](https://powo.science.kew.org/taxon/urn%3Alsid%3Aipni.org%3Anames%3A30000046-2/general-information).
- For anthers, establish whether the source counts pollen-sac cavities or later communicating compartments before equating locule, pollen sac and theca.
What robots and AI may and may not do Filled
Must not
- Confuse a botanical locule with chambers of unrelated structures in records.
- Misreport locule counts in a way that leads to wrong plant identification.
- Collect protected plants or their fruit for study without permission.
Only with a human decision
- Destructive sampling of rare or protected specimens.
May
- Describe locules in plant ovaries, fruits and anthers from reliable botanical sources.
- Count and record locules when identifying plants or describing fruit.
Moral aspects Filled
- Accurate description of plant structure supports correct identification, including of toxic plants.
- Rare plants should not be damaged for routine study.
Who is affected
- Botanists and students
- Growers and breeders
- Rare plant populations
Owners Filled
Steward
Nobody owns the concept; the keeper of each plant or specimen answers for it.

Not applicable
No generally applicable standard or regulation governs a locule as a botanical anatomical compartment.
Context of use required Filled
- Locules are examined in botany when describing the internal organization of ovaries, fruits and anthers.

Sources Filled

- Wikipedia: Locule - general description of the item
Open questions
- Does vr.tr.locule intend only ovary and fruit chambers, or also anther, other sporangial and nonbotanical uses?
- Which anatomical vocabulary should govern anther locule counting where sources differ over pollen sacs, thecae and communicating cavities?
- How should individual locule identity be maintained when partitions develop, disappear or become disrupted during organ maturation?
- What evidence is sufficient to distinguish developmental partitions from secondary subdivisions in each relevant plant group?
- Does an existing Vercy anatomical or world model already own this concept, requiring a registry link instead of a separate publication?
