What it is Filled
Linum usitatissimum L. is the domesticated annual flax of the family Linaceae, grown for stem bast fibre and highly unsaturated drying oil in the seed, with cultivar ideotypes that are either tall and sparsely branched for fibre or shorter and branched for linseed; the species includes both indehiscent and dehiscent capsule forms, so capsule indehiscence alone does not distinguish it from wild Linum.
In scope
- Species identification, supporting observations and unresolved lookalikes
- Cultivar or accession provenance and intended fibre, seed or dual-purpose use
- Germination, vegetative development, flowering, capsule formation and senescence
- Stem architecture, reproductive performance and plant condition
- Propagation, harvest readiness and volunteer management
Out of scope
- Independent models of related Linum species
- Field ownership, farm economics and whole-farm scheduling
- Soil, weather and irrigation-system models beyond linked exposure observations
- Extracted fibre, linen, pressed oil and processed food or feed products
- Pathogen taxonomy and pesticide product authorisations
- Commercial seed-lot grading, storage and certification beyond plant provenance links
Why it exists Filled
Enable an agent to recognise Linum usitatissimum, assess its development and condition, and select justified propagation, care, harvest or containment actions.
Distinguishing features Filled
- Check annual herbaceous growth, narrow simple leaves and five-parted flowers together; flower colour alone cannot establish identity because blue, pink and white occur. [CFIA botanical description](https://inspection.canada.ca/en/plant-varieties/plants-novel-traits/applicants/directive-94-08/biology-documents/linum-usitatissimum-flax)
- Against Linum marginale, check annual habit, free styles and a capsule longer than the calyx; larger, coarser parts provide supporting evidence in the Sydney regional key. [University of Sydney eFlora](https://eflora.sydney.edu.au/taxon/linum-usitatissimum)
- Inspect mature capsules and seeds: capsules may contain up to ten seeds, with smooth, shiny, flattened oval seeds approximately 4-6 mm long; use this combination as corroboration rather than a standalone identification. [CFIA botanical description](https://inspection.canada.ca/en/plant-varieties/plants-novel-traits/applicants/directive-94-08/biology-documents/linum-usitatissimum-flax)
- Do not separate fibre flax and linseed into different species: taller, less-branched versus shorter, more-branched architecture can support use-type interpretation, but cultivar provenance must resolve uncertain assignments. [CFIA botanical description](https://inspection.canada.ca/en/plant-varieties/plants-novel-traits/applicants/directive-94-08/biology-documents/linum-usitatissimum-flax)

Recognition required Filled
- The plant has slender upright stems bearing narrow, simple leaves arranged alternately.
- Flowers typically have five blue petals, although some cultivated forms have white flowers.
- Rounded dry capsules develop after flowering and contain flattened, smooth seeds that are commonly brown or golden.
- These features support identification, but similar flax species require additional botanical characters for reliable separation.
Capabilities and actions required Filled
- Inspect and sample leaves, flowers, capsules or seeds to resolve identification.
- Sow traceable seed and assess emergence and establishment.
- Adjust care using developmental stage, observed stress and locally supported guidance.
- Select and retain plants or seed for propagation with documented identity.
- Schedule stem or seed harvest against the intended output and observed maturity.
- Monitor and remove unwanted volunteers with attention to reproductive stage.
Hazards and failure modes required Filled
- Lodging can leave stems tangled or flattened, reducing harvestability and fiber quality.
- Fungal disease and mold can damage plants or make harvested material unsuitable for its intended use.
- Seed constituents can present ingestion hazards when material is used without an appropriate food or feed suitability assessment.
- Dry stems and accumulated fiber dust can contribute to fire hazards during storage and processing.
Standards and interfaces required Filled
- Council Directive 2002/57/EC, adopted by the Council of the European Union, governs the marketing of oil and fiber plant seed in the European Union and includes flax and linseed.
Context of use required Filled
- Cultivated flax is grown in agricultural fields for stem fiber, seed or both, depending on the cultivar and production system.
- Its fiber supplies linen and other fiber products, while its seeds supply food ingredients and oil for food or industrial uses.
- It is also encountered in crop breeding, agricultural research and collections of useful plants.
