Nutmeg is the seed or ground spice of several species of the genus Myristica.[1] Myristica fragrans (fragrant nutmeg or true nutmeg) is a dark-leaved evergreen tree cultivated for two spices derived from its fruit: nutmeg, from its seed, and mace, from the seed covering. It is also a commercial source of an essential oil and nutmeg butter. The California nutmeg, Torreya californica, has a seed of similar appearance, but is not closely related to Myristica fragrans, and is not used as a spice. Guatemala and Indonesia combined produced 68% of the world supply of nutmeg in 2018.
