Heterotypic synonyms [Taxonomy ]

Dictionary of botanic terminology - index of names

Synonyms: Taxonomic synonyms
 
     
  Heterotypic or Taxonomic synonyms are synonyms that refer to different types with which different names are associated, but which the scientist concerned considers to be the same taxon but different type  
     
Synonymy: why plants can have more than one valid name
Although each species is meant to have only one name under our system of nomenclatural rules, there are often several names that are applied under different circumstances. This is because some of them are to be applied following different classification systems, for example when different genera are recognized. Others are only applied when a narrow concept of the species is applied, falling into synonymy if the smaller species are lumped together into larger species, for which fewer names are required.
These names that can all apply to the same plant or group of plants are called synonyms, and there are different kinds of synonym:

Homotypic or nomenclatural synonyms: (Names belonging to the same type)
Each species recognized can only have one correct name within a particular genus Homotypic synonyms come about when a name is nomenclaturally incorrect or sometimes when a species is moved from one genus to another. Homotypic synonyms have a single (set of) type(s). One name is valid; other name(s) are invalid with reference to that type lot. Homotypic synonyms concerns names or combinations

Heterotypic or taxonomic synonyms: (Names belonging to the same taxon)
Heteroytpic synonyms are synonyms that refer to different types with which different names are associated, but which the scientist concerned considers to be the same taxon but different type
Heterotypic synonyms reflect a scientific opinion about distinctness of (terminal) taxa. Heterotypic synonyms always have different sets of types. One of the taxa is the currently accepted taxon.. Heterotypic synonyms concerns most often taxa at the terminal or subterminal levels
