The botanical name of groundnut is arachis hypogaea. Botanical names are a way to identify plants using a standardized system of names, which helps to avoid confusion caused by common names that can vary from region to region or even from person to person. The botanical name of a plant consists of two parts: the genus name, which is capitalized, and the species name, which is not capitalized. In this case, "arachis" is the genus name and "hypogaea" is the species name. Knowing the botanical name of a plant can help people communicate more effectively about it, as well as provide a more accurate way to identify it.
