 berq (I) has considered to belong to Mijurclla or to form the 

 stock of a new genus Aehrolepis. To me it appeared, even m 

 a barren state, to belong to Eunjnchium, a supposition which 

 T later found confirmed in finding the hitherto unknown 

 fruits, which possessed lids, provided with a very long point. 

 The great abundance of trnncs, besmeared with clay, is tne 

 great characteristic of the valley of the netlicr Jenisci. This

 region, although it is represented on a very small scale also 

 beyond this region in the under-woods ot bahccs and Al-
