For a successful publication of name, a scientific name must need an effective and valid publication by which this name will be acceptable in the whole world. The international code botanical nomenclature is based on the following sets of 3 principles, which are the philosophical basis of the code and provide guidelines for the taxonomists who propose amendments or deliberate on the suggestions for modifications of the code.
In biological nomenclature, It means that a set of rules which regulates how names of taxa have to be published to be recognized by the scientific community.
e.g. A taxon name is not effective whether it was not published in a scientific journal ( means printed matters has to be distributed to the general public or botanical institutions with libraries accessible to botanists generally).
A validly published name means, in the sense of botanical nomenclature, it fulfils all the requirements of ICBN ( International Code of Nomenclature for algae, fungi, and plants) for valid publication.
The process of selection of the correct name for a taxon involves the identification of illegitimate names, those which do not satisfy the rules of botanical nomenclature. A legitimate name must not be rejected merely because it or it’s epithet, is inappropriate or disagreeable, or because another is preferable or better known or because it has lost its original meaning.
These are either validated by another author at a later date by providing a description or if by that time the name has already been used for another species by some other author. The nomen nudum even if validated is rejected and a new name has to be found.
e.g. Quercus dilatata Wall. a nom. nud. rejected and replaced by Q. himalayana bahadur, 1972.
The words in the tautonym are exactly identical, and evidently names such as Cajanus cajan or Sesbania sesban are not tautonyms and thus legitimate. Repetition of a specific epithet in an intraspecific epithet does not constitute a tautonym but a legitimate autautonym. ( e.g. Acacia nilotica ssp. nilotica).
e.g. Ziziphus jujuba Lam. 1789 had long been used as the correct name for the cultivated fruit jujube. This, however, was ascertained to be a later homonym of a related species Z. jujuba Mill. 1768. Thus the binomial Z. jujuba Mill. is rejected and jujube finally named as Z. mauritiana Lam.
e.g. Baker (1892) and Christensen (1905) independently published the name Alsophila kalbreyeri as a substitute for A. podophylla Baker (1891) non Hook. (1857). As published by Christensen, Alsophila Kalbreyeri is later isonym of A. Kalbreyeri Baker. Without nomenclatural status.
e.g. Physkium natans Lour. 1790 thus when transferred to the genus Vallisneria, the epithet natans should have been retained but de Jussieu used the name Vallisneria physkium Juss. 1826 a name which becomes superfluous. The species has accordingly been named correctly as Vallisneria natans (Lour.)
