The betel-nut or areca palm is chiefly grown in certain favoured localities, such as the deltaic districts of Bengal and the highlands of southern India.
The Areca palm is a native of the Malay Peninsula and Islands and is extensively cultivated over a wide area in the East, including southern India, Ceylon, Siam, the Malay Archipelago and the Philippine Islands.
The betel nut is the fruit of the Areca or betel palm, Areca Catechu, and the betel leaf is the produce of the betel vine or pan, Chavica Betel, a plant allied to that which yields black pepper.
