From J. Beachy: "Kukui, sometimes called Candlenut, is a Polynesian introduction to Hawai'i. It is a non-native species, but is culturally important. The definition of a non-native species is: "This species arrived in Hawaiʻi moved (knowingly or accidentally) by people or our conveyances (boats, planes). " Kukui nuts were made into lei or tops, and the meaty/oily kernal inside the nut was burned for light, or used for food (inamona)."
