Asteraceae
Let an agent explain the Asteraceae and their characteristics, relay classification, diversity and uses from botanical sources, describe major subfamilies and genera, and distinguish Asteraceae from superficially similar families and the composite head from a single flower.

What it is Filled
The daisy or sunflower family, one of the largest families of flowering plants with over 32000 species in about 1900 genera, characterised by composite flower heads of many small florets, including sunflowers, daisies, asters, chrysanthemums, dandelions, lettuce, artichokes and many medicinal, ornamental and weedy plants; Asteraceae occur on every continent except Antarctica and are ecologically and economically important.
Why it exists Filled
Let an agent explain the Asteraceae and their characteristics, relay classification, diversity and uses from botanical sources, describe major subfamilies and genera, and distinguish Asteraceae from superficially similar families and the composite head from a single flower.
Distinguishing features Filled
- Composite heads
- Achene fruits with pappus
- Enormous diversity
- Cosmopolitan
What robots and AI may and may not do Filled
Must not
- Explain a composite head as a single flower in botanical description.
- Recommend eating or using a member of the family as food or medicine on identification alone.
- Advise planting a species where it is listed as invasive.
- Dismiss pollen allergy concerns about members such as ragweed.
Only with a human decision
- Advising on medicinal use of any plant in the family.
- Introducing a species into a new area.
May
- Identify a plant as a member of the family from its composite flower head and other features.
- Relay the family's ecology, crops and ornamentals from botanical sources.
- Flag species in the family that are invasive or allergenic in a region.
Moral aspects Filled
- Misidentification of wild plants as food or medicine can poison people.
- Some members cause severe hay fever or spread as invasive weeds that harm farmland.
Who is affected
- Foragers
- People with pollen allergies
- Farmers and native ecosystems
Owners Filled
Steward
Nobody owns a plant family; the holder of the land answers for plants on it, and botanic gardens keep reference collections.
