Botany Nomenclature Flashcards
In botany, where is there priority?
There is only priority within rank.
What is a homonyn?
A homonym is a name spelled exactly like a name based on a different type that was
previously and validly published for a taxon of the same rank
What is an epitype?
Epitypes are for when people only cite illustrations.
What is the principle of priority?
The oldest legitimate name takes precedence over all later published names. This was first used as a way to increase the stability of names.
How does nomenclature differ to taxonomy?
Nomenclature is independent of the science as it only represents rules for naming not how to designate or define taxa.
What is Superfluity?
A superfluous name is one where the taxon to which it was applied, as circumscribed by its author, definitely included the type of a name that ought to have been adopted.
What are Homotypic synonyms?
Homotypic synonyms have the same types and
therefore apply to the same taxa as a matter of fact.
What are Heterotypic synonyms?
Heterotypic synonyms have different types, and the
authors of this monograph have made the taxonomic
decision (a matter of opinion) that they all belong to the
same species and to the genus.
In order to name bacterial types what must be obeyed?
Types must be deposited as cultures into at least two different collections.
What is Candidatus?
Candidatus is used as a prefix for a bacterium that
can’t be kept in culture.
What form do virus names take?
Virus species names do not take the form of a Latin
binomial. Every new taxon from the species upwards has to be created by a proposal to the International Committee on the Taxonomy of Viruses (ICTV), which is reviewed by the Executive Committee and, if approved, is then ratified by a vote of ALL ICTV members.
