 found growing wild near Dumfries. 7j . V. 



This is a dioecious fhrub, the old branches of 

 which are terminated with thorns. 



The leaves are oval-hnceolate, finely ferrated on 

 the edges, their nerves converging together. 



The flowers grow in clufters, one on each foot- 

 flalk, white, and in this fpecies divided into 

 four fegments, containing fourj^atnina and one 

 Jlyle. The fruit is a round black berry, con- 

 taining four feeds. 



The juice of the berries, in the quantity of five 

 or fix drachms, is a ftrong purge •, but it is ge- 

 nerally made into a fyrup for this purpofe, two 

 ounces of which is a dofe. The bark is emetic* 

 The juice of the unripe berries with allum, 

 dyes a yellow color j of the ripe ones, a green
