A plant may have different names in different regions or the country of world. How do botanists solve this problem?

Explanation

There is a need to standardise the naming of living organisms such that a particular organism is known by the same all over the world. Botanists have solved this problem by setting International Code for Botanical Nomenclature (ICBN).
Scientific naming ensures that each organism has only name in any part of the world. ICBN ensures that such name has not been used for any other organism.
Each name has two components the generic name and the specific epithet. This system of naming is called bionomial nomenclature given by Carolus Linnaeus. e.g., mango has the scientific name Mangifera indica and potato is known as Solanum tuberosum.
