Pisum sativum
Let an agent explain the pea plant, relay botany, cultivation, nutrition and genetics history from botanical and agricultural sources, describe cultivar groups including the named convariety, and distinguish Pisum sativum from chickpeas, cowpeas, sweet peas and other legumes that share the name pea.
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 pea plant, relay botany, cultivation, nutrition and genetics history from botanical and agricultural sources, describe cultivar groups including the named convariety, and distinguish Pisum sativum from chickpeas, cowpeas, sweet peas and other legumes that share the name pea.
The pea plant, an annual climbing legume of the family Fabaceae, domesticated in the Near East about 10000 years ago, grown for its edible seeds and in some cultivars edible pods, including garden peas, field peas and edible-podded snow and sugar snap peas, the latter grouped in some classifications as Pisum sativum convar. axiphium; Gregor Mendel used peas for his experiments on heredity, and some botanists now place the species in Lathyrus as Lathyrus oleraceus.
What it is for: Food, feed and nitrogen-fixing crop.
It can be explain botany and cultivation; relay nutrition and genetics history; describe cultivar groups; distinguish other peas.
