Type genus

In botanical nomenclature, the phrase "type genus" is used, unofficially, as a term of convenience.

The 2008 Revision of the Bacteriological Code states, "The nomenclatural type […] of a taxon above genus, up to and including order, is the legitimate name of the included genus on whose name the name of the relevant taxon is based.

One taxon of each category must include the type genus.

The names of the taxa which include the type genus must be formed by the addition of the appropriate suffix to the stem of the name of the type genus[…].
