The descriptions of cryptog-amous plants are chiefly from 

 Sprengel, and Doctor Smith's translation of Acharius. The 

 orders, Algae and Fungi, are mostly from Tui'ton and Lin- 

 neus. 



This work should be accompanied by the Botanical Dic- 

 tionary, published at New-Haven, which was translated from 

 the French of Professor Richard ; and it is so constructed 

 that it may be bound in the isame volume.
