Ziziphusis a genus of about 40 species of spiny shrubs and small trees in the buckthorn family, Rhamnaceae, distributed in the warm-temperate and subtropical regions throughout the world. The leaves are alternate, entire, with three prominent basal veins, and 2-7 cm (0.79-2.8 in) long; some species are deciduous, others evergreen. The flowers are small, inconspicuous yellow-green. The fruit is an edible drupe, yellow-brown, red, or black, globose or oblong, 1-5 cm (0.39-2.0 in) long, often very sweet and sugary, reminiscent of a date in texture and flavour.The generic name is derived from zizfum or zizafun, the Persian word for Z. lotus. They are Rhamnaceae, near to the Buckthorn genus.
