油蜡树科也叫旱霸王科、旱黄杨科、荷荷巴科（由墨西哥的西班牙语]]名称jojoba音译而来的）和直接由拉丁名音译的希蒙得木科，只有1属—油蜡树属（Simmondsia）1种—油蜡树（Simmondsia chinensis (Link) C. K. Schneid. ），原生于北美洲干旱地带，种加名chinensis是命名者错误地将缩写“Calif”当成“China”造成的，实际在中国并没有原生种。目前在云南有引进种。 油蜡树是一种常绿灌木，1-2米高，单叶，对生，全缘，叶长2-4厘米，宽1.5-3 厘米，厚革质，无托叶；花两性，雌雄异株，雄花小，聚成头状，雌花单生，均无花瓣，花萼4-6；果实为蒴果，1-2厘米长，种子可提取透明而呈浅黄色的液体蜡，含量约达54％，可提炼出高级精密机械润滑油。 1981年的克朗奎斯特分类法将其列入大戟目，1998年根据基因亲缘关系分类的APG 分类法将其放在石竹目中。

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.
