Ziziphus Template:IPAc-en<ref>Sunset Western Garden Book, 1995:606–607</ref> is a genus of spiny shrubs and small trees in the buckthorn family, Rhamnaceae. It includes 68 species native to tropical and subtropical Africa, Eurasia, and Australia and tropical South America.<ref name = powo/> The leaves are alternate, entire, with three prominent basal veins, and often aromatic. The flowers are small, inconspicuous yellow-green. The fruit is an edible drupe, often very sweet and sugary, reminiscent of a date in texture and flavour.

Well known species include the commonly cultivated Ziziphus jujuba (jujube), Ziziphus spina-christi from southwestern Asia, Ziziphus lotus from the Mediterranean region, and ber (Ziziphus mauritiana), which is found from western Africa to India.

Etymology

The genus name is derived via classical Latin from Hellenistic Greek, where it is presumed to have been borrowed from another language, perhaps from zizfum or zizafun, the Persian word for Z. lotus.<ref>Template:Cite book</ref>

Ecology

Ziziphus species are used as food plants by the larvae of some Lepidoptera species including Bucculatrix zizyphella, which feeds exclusively on the genus, and Endoclita malabaricus.

Species are distributed throughout the world in tropical and warm temperate areas, from rain forests to deserts. Some species are evergreen, others are winter or drought deciduous.

Species adapted to dry climates are smaller and have oleifera cells that produce a fragrant aroma.
