Dealing with the scientific names of plants is decided by the International Code of Botanical Nomenclature
The code is headed for debates at International Botanical Congress hosted by International Association for Plant Taxonomy (IAPT)

Scientific name (学名)

Binomial nomenclature (二名法)
The International Plant Names Index (IPNI) (植物学名データベース)
Three components = generic name (属名) + species epithet (種小名) + authority (命名者名)

Oryza sativa Linne
Oryza = generic name, sativa = species epithet, Linne = authority

subspecies (subsp or ssp) (亜種), variety (var) (変種), forma (f) (品種) → followed species name, not shown only by these taxa

Philodendron scandens K. Koch et F. Sellow ssp.oxycardium (Schott) Bunt

ICBN (International Code of Botanical Nomenclature)
Syngameon: A group of genetically related organisms that may or may not be morphologically similar, and may belong to different genera

Synonyms (同種異名)


The synonym of a botanical scientific name is a name that also applies to this same taxon. A synonym can not exist in isolation: it is always "a synonym of …". For plant ecologists, the selection of scientific names is one of the problems.
In botany synonyms can be:
  1. homotypic (or nomenclatural): having the same type. The Linnaean name Pinus abies L. has the same type as Picea abies (L.) H. Karst. When the latter is taken to be the correct name (there is almost complete consensus on that), Pinus abies is a homotypic synonym of Picea abies. However, if the species were regarded to belong to Pinus (now unlikely) the relationship would be reversed and Picea abies would become a homotypic synonym of Pinus abies.
  2. heterotypic (or taxonomic): with a different type. Some botanists split the dandelion into many, quite restricted species. The name of each such species has its own type. When the dandelion is regarded as including all those small species, the names of all those species are heterotypic synonyms of Taraxacum officinale F.H.Wigg. Reducing a taxon to a heterotypic synonym is termed "to sink in synonymy" or "as synonym".
  1. superfluous synonyms
In botany it is not required that a synonym be a valid name: a listing of synonyms often contains names that for some reason did not make it as a formal name (unpublished or manuscript names), or have not yet been formally published. Such a synonym must have the form of a formal name: it must look like a proper 'Latin name'.
A homotypic synonym need not share an epithet or name with the correct name, but only the type. For example the name Taraxacum officinale, mentioned above, has the same type as Leontodon taraxacum L. The latter is a homotypic synonym of Taraxacum officinale F. H. Wigg.
Basionym (basyonym, 基礎異名)
a previously published legitimate name-bringing or epithet-bringing synonym from which a new name is formed for a taxon of different rank or position (ICBN)
Homonym (異物同名)
a name for a taxon that is identical in spelling to another such name, that belongs to a different taxon

Typology (類型分類学)


Typological species

Species identified by the type specimen
Morphospecies (形態種): species named by typology

Type specimen (基準標本)

  1. holotype: the one specimen or illustration used by the author, or designated by the author as the nomenclatural type
  2. paratype: a specimen cited in the protologue that is neither the holotype, isotype, nor one of the syntypes. These are often listed as representative specimens in the original description

    syntype = all specimens of (holotype + paratype)

  3. isotype: any duplicate specimen of the holotype
  4. lectotype: a specimen or illustration designated as the type when no holotype was indicated at the time of publication. If possible, the lectotype should be selected from the syntypes or original material.
    Isolectotype: any duplicate specimen of the lectotype
  1. neotype: a specimen or illustration selected as the type when all of the material on which the name of the taxon was based is missing
