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 common pear tree, relay its botany, cultivation and cultivars from horticulture sources, describe the varieties its aliases name, and distinguish the species from Asian pears and from other fruit trees.

The species of tree that bears the common or European pear, the pear of orchards and shops, grown across temperate regions for its sweet fruit; the registry aliases name cultivated varieties such as historic and regional pear cultivars. Pyrus communis is a fruit tree of the rose family, and its many cultivars differ in fruit shape, flavour and season, so a named cultivar is a variety within the species.

What it is for: Not applicable; a fruit tree species.

It can be explain the species; relay botany and cultivation; describe cultivars; distinguish it from other pears.
