What it is Filled

Cannabis sativa is an annual, typically dioecious flowering plant of family Cannabaceae whose cultivated and feral forms are distinguished in practice by chemistry (THC/CBD), use (fibre, seed, drug) and, in some taxonomic treatments, by subspecies or cultivar groups rather than by a single morphological species concept.

In scope

  • Botanical identification and the taxonomic interpretation used to assign Cannabis sativa
  • Accession, cultivar and propagation provenance, with uncertainty preserved
  • Vegetative development, flowering, sex expression, pollination and seed formation
  • Plant condition, environmental exposure and suspected biological damage
  • Organ-specific chemical observations and their sampling limitations
  • Evidence needed to assess proposed handling, sampling, transfer or removal

Out of scope

  • Manufacturing, formulation and quality control of extracted cannabinoids or finished cannabis products
  • Human intoxication, diagnosis, therapeutic efficacy and clinical dosing
  • Cultivation-facility design and commercial production scheduling
  • Complete population ecology, land management and regional invasive-species assessments
  • The content and interpretation of jurisdictional laws, licenses and enforcement procedures
  • Commodity specifications for detached fiber, food seed, oils and harvested flower batches

Why it exists Filled

Distinguishing features Filled

  • Inspect whether mature leaves consist of separate, serrated leaflets radiating from one attachment, rather than a single deeply lobed blade; record juvenile or reduced upper leaves separately. [Flora of China](https://efloras.org/florataxon.aspx?flora_id=2&taxon_id=105522)
  • Use erect herbaceous habit together with palmately compound leaves and petiole characters to distinguish Cannabis from the related Humulus; a leaf silhouette alone is insufficient. [Flora of North America](https://www.efloras.org/florataxon.aspx?flora_id=1&taxon_id=10154)
  • Check leaf arrangement at several stem positions: lower leaves can be opposite while upper leaves are alternate, so one isolated node is a weak identification test. [Flora of Pakistan](https://www.efloras.org/florataxon.aspx?flora_id=5&taxon_id=105522)
  • Require a botanical determination tied to a named taxonomic treatment when interpreting labels such as 'sativa' or 'indica'; record a commercial label separately from the species assignment. Kew accepts Cannabis sativa L. as a species. [Plants of the World Online](https://powo.science.kew.org/taxon/urn%3Alsid%3Aipni.org%3Anames%3A306087-2)
  • Require measured composition and an applicable classification rule to evaluate a 'hemp' claim; record the claim as unresolved when those inputs are missing rather than treating it as a visual identification.

Open questions

  • Which sampling protocols justify extrapolating cannabinoid measurements from one organ or date to an individual plant or population?
  • Which developmental and condition assessments are validated across different accessions and growing contexts rather than assumed from a single cultivar?
  • Which existing Vercy models already own this species concept, detached propagules, harvested cannabis material and jurisdiction-specific permissions, and where must this draft link rather than duplicate?
