Question

Answer 1

Answer:

Before the middle of the 18th century, plant names were usually polynomials i.e. made up of several words in a series. It was superseded by the binomial system, which was first applied for the plant kingdom by Linnaeus in his Species Planetarium. It was Linnaeus who proposed the elementary rules of naming plants first in 1737 in his Critica botanica and then in 1751 in Philosophia Botanica.

Elementary rules were framed to serve as a guide to botanists. Later in 1813, A.P. de Candolle in his Theories elementary de la botanique gave a detailed set of rules regarding plant nomenclature.

Answer 2

Answer:

The International Code of Botanical Nomenclature (ICBN) is the set of rules and recommendations dealing with the formal botanical names that are given to plants. Its intent is that each taxonomic group ("taxon", plural "taxa") of plants has only one correct name that is accepted worldwide
