The coconut palm (also, cocoanut), 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, botanically, is a drupe, not a nut. The spelling cocoanut is an archaic form of the word.The term is derived from 16th-century Portuguese and Spanish coco, meaning "head" or "skull",from the three small holes on the coconut shell that resemble human facial features.
