The coconut palm, 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, 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
indentations on the coconut shell that resemble facial features.
