6 bundles · 11 layers · 18 findings · 28 questions

Bottle-gourd identity Establish whether the observed plant or detached material belongs to the registered species.

Diagnostic organs

Record the organs available for checking the species attribution.

Combined identification evidence

An identification assessment should state which vegetative, floral and seed observations support it and which alternatives remain.

  1. Which observations of tendrils, leaves, male flowers and seeds support Lagenaria siceraria? definition
  2. Which alternative identification remains plausible when flowers or parent-plant evidence are missing? boundary

Accession continuity

Connect the specimen and its parts to their source without treating cultivar labels as separate registry things.

Parent and source link

Detached fruits and seeds need explicit links to their source plant or lot, with labels distinguished from verified identity.

  1. Which parent plant, seed supplier or accession record supports this material's identity? provenance
  2. Is the cultivar name documented, locally assigned or inferred from fruit shape? provenance
Vine growth and condition Assess the living vine's development, physical support and visible decline.

Vine and fruit support

Record trailing or climbing growth and the physical disposition of attached fruits.

Attachment and load

Support decisions should use observed attachment, fruit load and contact conditions.

  1. Where are tendrils attached, and which fruits are suspended or touching the ground? measurement
  2. Does observed strain, constriction or abrasion justify adjusting vine or fruit support? action

Organ condition

Track foliage, stem and fruit symptoms against developmental stage.

Decline with evidence

Record symptoms and their progression before assigning causes or selecting treatment.

  1. Which leaves, stems or fruits show wilting, discoloration, lesions or damage, and how has the affected area changed? measurement
  2. What evidence distinguishes seasonal senescence from a stress or disease requiring investigation? boundary
Flowering and seed continuity Connect flower observations, fruit retention and seed performance.

Flower to fruit

Follow observed flowers through pollination opportunities and subsequent fruit development.

Fruit-set evidence

Keep flower availability, observed pollination and later fruit growth as separate observations.

  1. When were male and female flowers open, and what pollinator visits or hand-pollination events were observed? measurement
  2. Which tagged female flowers produced retained, enlarging fruits rather than aborted ovaries? measurement

Seed performance

Assess whether harvested seeds have usable provenance and demonstrated germination.

Propagation readiness

Propagation decisions require seed-source records and an explicit account of what testing establishes.

  1. Which fruit supplied the seeds, and was its pollen parent controlled, observed or unknown? provenance
  2. What fraction germinated under the recorded test conditions, and is that evidence sufficient for the intended sowing? action
Fruit maturity and food decision Assess harvest purpose, developmental condition and reasons to withhold food use.

Purpose-specific maturity

Judge readiness against the intended vegetable, seed or shell use.

Harvest-purpose fit

Maturity should be supported by observed fruit properties and a cultivar-appropriate criterion.

  1. Is this fruit intended for vegetable use, seed recovery or shell preparation? definition
  2. Which observations of rind, flesh, seeds and development support harvesting it for that purpose now? action

Food-use exclusion

Record adverse observations and unresolved evidence relevant to food use.

Suspect fruit disposition

Keep reported bitterness, deterioration and uncertain history visible in the disposition decision; do not request tasting as an identification test.

  1. Has bitterness already been reported, or is there evidence of decay, contamination or an unknown treatment history? provenance
  2. Should this fruit and related material be withheld from food use pending assessment? action
Harvested gourd and shell Follow detached fruits through storage or drying to an explicit material handoff.

Postharvest condition

Retain harvest history and observe changes during storage or drying.

Drying versus deterioration

Use a sequence of observations to assess progress and detect damage without assuming that an externally dry fruit is sound internally.

  1. When was the fruit harvested, at what recorded maturity, and under what conditions has it been stored? provenance
  2. How have mass, firmness, visible growth and soft areas changed during drying? measurement

Shell handoff

Assess unworked shell properties and define the boundary with a manufactured artifact.

Material readiness

Transfer to a craft or manufacturing model should preserve botanical provenance and the evidence behind shell selection.

  1. Do shell dimensions, accessible wall thickness, cracks and drying evidence meet the intended workshop's criteria? measurement
  2. At which processing step does the object become a vessel, instrument or other artifact requiring a neighbouring model? boundary

What it is Filled

Lagenaria siceraria is a monoecious, night-blooming annual cucurbit vine whose immature fruit is eaten as a vegetable and whose mature fruit dries to a hard, waterproof lignified rind long used as containers, utensils and resonators; it was domesticated from an African wild progenitor and is among the earliest plant remains in both Old World and pre-Columbian American assemblages.

In scope

  • Identification of living plants, detached fruits and seeds, including uncertainty
  • Cultivar or accession provenance without splitting the registered species
  • Vine development, flowering, fruit set and observable stress
  • Fruit maturity and suitability for a declared harvest purpose
  • Seed viability and unworked shell condition

Out of scope

  • Taxonomic nomenclature governance and species-wide evolutionary history
  • Farm planning, irrigation infrastructure and cultivation schedules
  • Pollinator, pest and pathogen models beyond their observed effects on this plant
  • Recipes, processed foods, clinical treatment and medicinal efficacy
  • Finished gourd vessels, instruments and other manufactured artifacts

Why it exists Filled

Distinguishing features Filled

  • For a living specimen labelled calabash, check for an herbaceous climbing or trailing plant with tendrils; the common name alone cannot resolve identity. [Kew botanical description](https://powo.science.kew.org/taxon/urn:lsid:ipni.org:names:134809-2/general-information).
  • Check white flowers and solitary male flowers together; colour alone is insufficient for identification. [Kew botanical description](https://powo.science.kew.org/taxon/urn:lsid:ipni.org:names:134809-2/general-information).
  • Compare a male flower's short, funnel-shaped receptacle tube with the longer cylindrical tube and usually clustered male flowers described for Lagenaria breviflora. [L. siceraria](https://powo.science.kew.org/taxon/urn:lsid:ipni.org:names:134809-2/general-information), [L. breviflora](https://powo.science.kew.org/taxon/urn%3Alsid%3Aipni.org%3Anames%3A293036-1/general-information).
  • Use compressed, oblong seeds with facial ridges as corroboration where present; cultivated variation means neither this feature nor bottle-shaped fruit is a universal identification requirement. [Kew botanical description](https://powo.science.kew.org/taxon/urn:lsid:ipni.org:names:134809-2/general-information).

What robots and AI may and may not do Filled

Must not

  • Present bottle gourd juice as a proven cure for disease.
  • Sell bitter fruit as safe for food.
  • Misrepresent a gourd craft object's origin or age.
  • Recommend tasting potentially toxic fruit or juice to assess its safety.

Only with a human decision

  • Selling or exporting cultural gourd objects requires human involvement.

May

  • Identify the plant and report its uses as food and as dried gourd containers.
  • Warn that potentially toxic bottle-gourd fruit or juice is unsafe to consume.

Moral aspects Filled

  • Bitter gourd juice has caused serious illness, so honest warnings matter.
  • Gourd instruments and vessels carry cultural meaning in many communities.

Who is affected

  • People who eat or drink it
  • Craft communities

Owners Filled

Steward
