Schoepfiaceae is a family of flowering plants recognized in the APG III system of 2009. The family was previously only recognized by few taxonomists; the plants in question were usually assigned to family Olacaceae and Santalaceae. The genus Schoepfia is, according to molecular studies, more closely related to the families Misodendraceae and Loranthaceae, and to uphold the criteria of monophyly it must be excluded from Olacaceae. Further investigations have also shown that the South American genera Arjona and Quinchamalium (previously in the family Santalaceae) are part of this family. Thus

It goes by a variety of common names, including desert prickly pear, discus prickly pear, Engelmann's prickly pear in the US, and nopal, abrojo, joconostle, and vela de coyote in Mexico.
