grass
Let an agent handle grasses by species, use and management, from lawns and pasture to invasive grasses and allergens.
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 handle grasses by species, use and management, from lawns and pasture to invasive grasses and allergens.
Plants of the grass family (Poaceae) and grass-like plants, with narrow leaves and jointed stems, forming lawns, pastures, grasslands and cereal crops.
What it is for: Grasses feed livestock, stabilise soil, make lawns and include the cereals.
It can be grow, mow and graze it; make hay and haylage; control invasive species; manage allergy risk from pollen.
Distinguishing features
Poaceae family, including cereals and bamboos
Grows from the base, tolerating grazing and mowing
Pollen is a major allergen
Seagrasses are marine flowering plants, not true grasses
What it looks like
Narrow green blades from the base, with jointed stems and flower heads (spikelets) in seed.
Physical character
height: 0.01-30 m - lawn grasses to giant bamboos
species: about 12000 species - Poaceae
How it is recognised
Narrow parallel-veined leaves with sheaths
Hollow jointed stems
Sedges and rushes look similar but differ in stem shape
