What it is Filled

Any of a large group of seedless vascular plants that reproduce by spores, with roots, rhizomes and fronds that unfurl from coiled fiddleheads; ferns grow in forests, wetlands, rock crevices and gardens on every continent except Antarctica, from tiny filmy ferns to tree ferns, and have an ancient fossil record.

Why it exists Filled

Let an agent identify ferns as a plant group, explain their life cycle and main families, relay cultivation, conservation and toxicity information from botanical and horticultural sources, and separate ferns from mosses, clubmosses and flowering plants.

Distinguishing features Filled

  • Spore reproduction with a free-living gametophyte
  • Vascular tissue without seeds or flowers
  • Fronds and fiddleheads
  • Ancient lineage

What robots and AI may and may not do Filled

Must not

  • Collect ferns from the wild where they are protected or from land without permission.
  • Recommend eating fiddleheads or ferns without warning that some species are toxic.
  • Spread invasive fern species into new areas.

Only with a human decision

  • Removing ferns from protected habitats for research or restoration.

May

  • Identify ferns and describe their life cycle and habitats.
  • Care for ferns in gardens and collections on the keeper's instructions.

Moral aspects Filled

  • Wild collecting has threatened rare ferns.
  • Some ferns are toxic to people and livestock.

Who is affected

  • Rare fern species
  • Foragers
  • Livestock keepers

Owners Filled

Steward

The landowner or the person who keeps it; nature authorities protect rare species.

Master systems

  • Species and biodiversity databases

Links to other meta-models Filled

parent

  • oewn-11565975-n - registry parent class

related

  • vascular plant - seedless vascular plants
  • moss - non-vascular plants
  • horsetail - a related seedless group
  • clubmoss - lycophytes, a separate lineage

What else AI and robots need to interact with it Filled

Identity and identifiers required Filled

  • Vercy registry: vr.tr.fern
  • Open English WordNet: oewn-11566165-n
  • taxon: Polypodiopsida class of ferns in current classifications

Direct properties required Filled

  • species: about 10000 species
  • height: a few centimetres to over 20 m - tree ferns at the top

Recognition required Filled

  • Fronds unfurling from fiddleheads
  • Spore clusters on the underside of fronds
  • Mosses lack vascular tissue; clubmosses and horsetails are related but distinct groups
  • Plants with divided fronds arising from a rhizome, spore cases on the frond undersides, and young fronds coiled as fiddleheads.

Capabilities and actions required Filled

  • identify fern groups and common species
  • explain the spore life cycle
  • relay cultivation and care guidance
  • relay conservation and toxicity information

Hazards and failure modes required Filled

  • Toxicity of bracken to livestock and carcinogens in bracken
  • Invasive ferns in some regions
  • Over-collection of wild ferns
  • Misidentification of edible fiddleheads

Standards and interfaces required Filled

  • CITES listings for tree ferns and some species
  • National wild plant protection laws
  • Plant health rules on movement of plants

Context of use required Filled

  • Not for anything; a plant group, though used in gardens and some as food.
  • tree ferns
  • filmy ferns and bristle ferns
  • aquatic ferns
  • epiphytic ferns such as staghorns
  • garden and house ferns
  • fossil ferns and fern-like plants such as Pecopteris

  2. Wiktionary: fern - word senses and usage

Open questions

  • Should major fern families be separate entries?
  • How should regional floras be linked?
  • The registry entry has merged aliases naming specific filmy fern species; should they be split off?
