Question

Write any five salient features of ICBN.

Answer 1

Hint: ICBN stands for International Code for Botanical Nomenclature. It provides the principles and criteria, which are agreed upon by biologists worldwide while naming the plants.

Complete answer:
Some important principles of ICBN:
-Botanical nomenclature is independent of the zoological and bacteriological system of nomenclature.
- The application of names of taxonomy groups is determined using the nomenclature types.
- The nomenclature of a taxonomic group is based on the priority of publication.
- Each taxonomic group with a particular rank and position can bear only one correct name, the earliest that is per the Rules, except in specified cases.
- Scientific names of taxonomic groups are regarded as Latin regardless of their derivation.
- Anyone proposing a change in the Code needs to consider the effect that the proposed change would have on the names published in a wide range of literature and over a considerable time.
Various rules proposed by ICBN:
- The first letter of a genus should be capitalised while the species name should begin with a small letter.
- The name should be simple and easy to pronounce. There are no two organisms with the same name.
- Binominal should be printed in italics or underlined. The generic and specific epithets are underlined separately
- When a new name is given to a plant, then herbarium preparation of the plant is preserved for future references.
- And the person who first publishes the description of a new plant or names it.

Note:
 -Binomial nomenclature: It is also called as binomial nomenclature or binary nomenclature. It is a formal system of naming organisms and the name consists of two words.
-Herbarium: It is a collection of preserved plant specimens and associated data used for scientific study.
