Fossil pollen named Bluffopollis scabratus, found in deposits from the Paleocene to the Miocene, is almost identical to the

Simmondsiaceae or the jojoba family is a family of flowering plants. The family is not recognized by all taxonomic systems, the single species, Simmondsia chinensis, often being treated as belonging to the family Buxaceae. The APG II system, as of 2003 (unchanged from the APG system, of 1998), does recognize this family and assigns it to the order Caryophyllales in the clade core eudicots. It consists of a single species only, jojoba (Simmondsia chinensis), of North American shrubs. The Cronquist system, 1981, had also recognized this family and placed it in the order Euphorbiales.
