[Fr. jujube, from Lat. zizyphum, Gr. ζίζυφον, Per. zizafun, zizafun, zayzafun, zirfun, the barren jujube tree; Ar. zifzāf, zūfayzaf.] The fruit of a species of plant of the order Rhamnaceæ (Rhamnus zizyphus), a native of Syria, but now cultivated in the south of Europe: it is of a blood-red or saffron color, and has a sweet, granular pulp, and was formerly used in pectoral preparations.
