Naming of plants correctly and scientifically is known as plant nomenclature. The rules of naming the plants are framed by Internation Botanical Congress (IBC) and coded in the International code of Botanical Nomenclature (ICBN). Scientific names of plants and animals consist of two words and the system is called Binomal Nomenclature. Gaspared Bauhin (1623) first used it but Carolus Linnaeus (1707-1778) is credited for introduction of this system through his publication Species Plantarum (1753).
Each plant name consists of two Latin or Latinised words; the first is generic name and the second specified epithet (trivial name). Generic name is always a noun (substantive) and is written with capital letter. Whereas the specific epithet is usually an adjective (descriptive) and is written with a small letter. The binomial name followed by the full or abbreviated name of the authors(s) who published it correctly for the first time, e.g. Solanum tuberosum L.( Like stands for Linnaeus)
