The taxonomic genus that is designated as representative of the family to which it belongs. The type genus is usually the first genus in the family to be named, or the genus that is considered most important. Families are named after type genera. For example, the dinosaur Tyrannosaurus is the type genus for the family Tyrannosauridae.
The type-genus Botryopteris, represented in the Permo-Carboniferous of France and in both the Lower and Upper Carboniferous of Great Britain, had a rhizome, with a very simple monostelic structure, bearing spirally arranged compound leaves, with lobed pinnules, probably of a somewhat fleshy texture.
