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 citrus genus and its species and hybrids, describe cultivation, diseases and industry, support growing and culinary questions, and describe origins and diversity.

A genus of flowering trees and shrubs in the rue family producing the citrus fruits, including oranges, lemons, limes, grapefruit, pomelo, mandarins, kumquats and hybrids, together with wild and regional species such as the kaffir lime and Madagascan citrus, cultivated worldwide in warm climates for fresh fruit, juice, oils and flavouring; citrus is one of the most important fruit crops, threatened by diseases such as citrus greening, and diverse in cultivars such as the Scillato blonde orange.

What it is for: Trees and fruits of the citrus genus.

It can be explain species and hybrids; describe cultivation and diseases; support growing and culinary questions; describe origins.

How it is recognised

Genus producing oranges, lemons, limes and relatives

Segmented juicy fruit with oil-rich peel
