Provisional names in bacteriology
In bacteriology, a valid publication of a name requires the deposition of the bacteria in a Bacteriology Culture Collection. Species for which this is impossible cannot receive a valid binomial name; these species are classified as Candidatus.
Provisional names in botany
A provisional name for a species may consist of the number or of some other designation of a
correct name. For example, the name "Endressia" (sensu Whiffin) was published in 2007 for a genus in family Monimiaceae, but is an illegitimate homonym of Endressia J.Gay in family Apiaceae. In 2010, it was noted as illegitimate, but still used with quotation marks.[2] This name was replaced with Pendressia in 2018.[3]
