Kakala/en

A kakala is the Tongan term for any plant, be it its wood, flower, or seed, which has a good smell. It is often translated as 'flower', but that is not always correct. It is also a requirement that there is a mythical origin for the plant. As such introduced plants, like the kalonikakala are no kakala despite their smell, as there is no (not yet) a myth about their origin invented.

The kakala are divided into 2 groups: the named or known kakala (kakala hingoa, kakala ʻiloa ), which are for the use of the chiefs, and the stupid kakala (kakala vale), which are for the normal people.
