area. De Candolle's Prodromus contains, in Latin, a descrip- 

 tion of all known plants. In cryptogamic botany, the work 

 of Berkeley is scarce but very good, Sachs and Bessey both 

 include cryptograms in their structural books. The older edi- 

 tions of 'Gray's Manual' include both ferns and mosses, but 

 the mosses are left out of the later editions. Cooke's Fungi 

 applies almost as well to the United States as to England. 

 Wolle's books on Desmids and Fresh Water Algae take the 

 place of all others on these subjects for the United States.)
