More Scientific Information

In naming plants, botanists use a Latin name made up of the genus and species of the plant. For example, under this system the plant, the Brazil nut tree is known as Bertholletia excelsa Humb. & Bonpl. where ” Humb. & Bonpl. ” stands for the names of the people, who first described the type of plant specimen. Plants are also known by a common name that has been handed down through generations. These common names may vary from country to country. Therefore, Latin names, which are more likely to be recognized in many countries, are frequently used on the label of a product to identify an ingredient made from plants.
