As valid publication ( valid publication ) is called in the Botany so that they (and thus the scientific name) recognizes a particular form of publication of a scientific name. The validity only refers to the form and the name, a statement about the content of the publication is not made.

Such a publication is subject to very specific conditions, which are listed in the International Code of Botanical Nomenclature (ICNafp) in Articles 32-45.

Among other things, you need:

• A diagnosis or description, or an indication of such (the absence of which is a noun nudum , a scientifically unrecognized name).
• Since January 1, 1935, the diagnosis or description must be written in Latin.
• Since January 1, 1958, it is also necessary to specify the nomenclature type .

The date of a valid publication is decisive for the priority .

The correct spelling of a name is that used in the first valid publication (unless typographical or orthographic errors are corrected). The use of the ending - eranus instead of - erianus in epithets derived from personal names ending in -er is regarded as an "orthographical error" that must be corrected ; The following are correct: barkerianus , hookerianus , kramerianus , sanderianus , schillerianus , schroederianus , spicerianus , spindlerianus , walkerianus etc.
