Is nutmeg a herb or shrub or tree?

Nutmeg is the seed of the nutmeg tree, scientifically known as Myristica fragrans. This tree is native to the Spice Islands of Indonesia and can grow up to 20 meters tall. The spice is derived from the seed itself, while the outer covering, called mace, is also used as a spice. Thus, nutmeg is not a herb or shrub, but rather the product of a tree.
