In India, the tree goes by a variety of names, many deriving from the Sanskrit kētakī (केतकी). In Tamil, it is called kaithai (கைதை) and thazhai (தாழை) and both are mentioned in Sangam literature. In Arabic speaking countries, the tree is referred to as al-kādi (الكادي). In Japan, the tree is called adan (アダン ) and grows on Okinawa.
