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

Different plants have different names that may be given by the local population or the name may be popular throughout the country. But often these local names aren’t common throughout the world. They are often known by different names in different parts of the world. To solve this problem, plants →and animals) are given scientific name. This scientific name is common throughout the world. For example: A mango is known as a mango in certain English speaking countries. However it is called Aam in Inida. But it has only one scientific name which is common throughout the world and it is Mangifera indica.
