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.
Research draft, second pass
A second pass drafted this model: the structure a model of this thing needs, and what is known about it in the world. The line under this one says how the second half was obtained - researched against sources, or recalled without web access, in which case nothing here was read anywhere and every claim is a lead to verify. Unreviewed either way.

Purpose and description
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.
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.
What it is for: Not applicable; a plant family.
It can be explain characteristics; relay classification and diversity; describe uses; distinguish related families.
Distinguishing features
Composite heads
Achene fruits with pappus
Enormous diversity
Cosmopolitan
What it looks like
Plants with composite flower heads of disc and ray florets.
Physical character
species: over 32000 count
genera: about 1900 count
subfamilies: 12-13 count - current classifications
largest genera: Senecio, Vernonia, Cousinia list
How it is recognised
Plants with composite flower heads
Sunflowers, daisies, asters, chrysanthemums, dandelions, lettuce, artichokes
Dipsacaceae and some Apiaceae have head-like inflorescences but differ in structure
