Study Notes

Taxonomic Nomenclature

Multiple names may refer to the same taxon, leading to confusion in taxonomy.
Homonyms occur when two or more names with identical spellings apply to different taxa.
Synonyms involve different names for the same taxon, while name variations may arise from different spellings.

Example of a Homonym

Myroxylon L.f. (1782) in the family Leguminosae is conserved; it takes precedence over the earlier homonym Myroxylon J.R.Forst. & G.Forst. (1775), which is now identified as Xylosma in the Salicaceae family.

Neotype Concept

A neotype is selected as a single representative specimen when the original holotype is lost, destroyed, or never identified by the original author.

Types of Taxonomic Specimens

A lectotype is a specific type of specimen that acts as a name-bearing type and serves as an authoritative reference for the taxon.
Syntypes are multiple specimens that can function together as name-bearing types, with one being chosen as the lectotype.

Importance of Latin in Scientific Naming

Latin, as a dead language, remains constant and unalterable, providing stability in scientific nomenclature.
Scientific names maintain consistency globally, regardless of local languages, eliminating discrepancies across countries.
