High Quality Content by WIKIPEDIA articles! The coconut palm, Cocos nucifera, is a member of the family Arecaceae (palm family). It is the only accepted species in the genus Cocos. The term coconut can refer to the entire coconut palm, the seed, or the fruit, which is not a botanical nut. The spelling cocoanut is an old-fashioned form of the word. The term is derived from 16th century Portuguese and Spanish cocos, meaning "grinning face," from the three small holes on the coconut shell that resemble human facial features.
