 approximately 15,000 specimens, chiefly of European plants, and is 

 especially rich in Characece, Violce, and Epilobia. The Characece 

 alone are represented by upwards of 2200 critically determined speci- 

 mens, and the Viola by about 1500 specimens. Some of the more 

 noteworthy series of exsiccates, illustrating these groups of plants 

 included in the herbarium, are the following: Die Characeen Europa's
