ORDER XLIX. RHAMNE^. 



The best known genera of this family are Rhamniis and Zizyphus. 

 One or more species of Rhamnus have purgative properties, and are 

 used medicinally, as Syrup of Buckthorn. Other species yield dyes, 

 which are, however, but little used. The fruits of several species of 

 Zizyphus are eatable, and the fi'uits and bark of some other members 

 of the Order have been, and perhaps are, still used medicinally. None 

 of our species have any special value. 



Number of species about 430.
