Principal of priority and its limitations.
Answers
Answer:
Sanzinia madagascariensis was moved to the genus Boa. To avoid having the same name as another snake it was renamed Boa manditra. On further investigation it was established that the move had been incorrect, so the original name was reinstated as the valid name.
The North American wildflower genus Agalinis was published in 1837, but for a long time it was included in the ambiguously-named genus Gerardia. In 1961 the problem with the name Gerardia was resolved, and Agalinis came into common use. However, three relatively unknown names for the genus had been published earlier Virgularia Ruiz & Pav. in 1794, Chytra C.F.Gaertn. in 1807, and Tomanthera Raf. in 1837, of which Virgularia would have priority.[1] These three names have since been rejected in favour of Agalinis.[2]
Priority is a fundamental principle of modern botanical nomenclature and zoological nomenclature. Essentially, it is the principle of recognising the first valid application of a name to a plant or animal. There are two aspects to this:
The first formal scientific name given to a plant or animal taxon shall be the name that is to be used, called the valid name in zoology and correct name in botany.
Once a name has been used, no subsequent publication of that name for another taxon shall be valid (zoology) or validly published (botany).
There are formal provisions for making exceptions to this principle. If an archaic or obscure prior name is discovered for an established taxon, the current name can be declared a nomen conservandum (botany) or conserved name (zoology), and so conserved against the prior name. Conservation may be avoided entirely in Zoology as these names may fall in the formal category of nomen oblitum. Similarly, if the current name for a taxon is found to have an archaic or obscure prior homonym, the current name can be declared a nomen protectum (zoology) or the older name suppressed (nomen rejiciendum, botany).
