Jojoba, Simmondsia chinensis, is a shrub which grows in Arizona and adjacent parts of Mexico and is grown for the liquid wax (commonly called oil) in its seeds, which is similar to sebum, does not go rancid, and is therefore used in cosmetics as a moisturizer and as a carrier oil. Jojoba does not come from China; the botanist, Link, who originally named the species Buxus chinensis, misread Nuttall's label "Calif" as "China". It was later renamed Simmondsia californica, but priority rules require that the original specific epithet be used.

The southern range of Simmondsia chinensis, or Jojoba, is halted in the central and southern portions of Sonora, Mexico where the relatively wet summers and somewhat dry winters conflict with the preferred precipitation patterns of Jojoba.
Simmondsia chinensis is well suited to areas that receive relatively more winter rain and less summer precipitation.
The most intriguing aspects of Simmondsia chinensis however center around the oil found in its seeds.
