The scientific name honors Captain William Bligh who took the fruit from Jamaica to the Royal Botanic Gardens in Kew, England in 1793 and introduced it to science. The English common name is derived from the West African Akan akye fufo.

Ackee is the national fruit of Jamaica and is considered one of the country's best delicacies.
