l-_. RIIAJCNUS FRANGULA, L. (Black Alder, Alder Buckthorn.) 

 a. Bark. 



Note. This bark has been lately brought forward in this country as 

 an excellent purgative, free from the griping properties of Buckthorn 

 berries. It contains a little prussio acid. The berries of 11. Frangula 

 differ from those of K. catharticus in having only three seeds, and the 

 leaves are entire and feather-veined, not serrulate as in R. catharticus.
