of tlieir growth, suggesting' an analogy with tlie imrtlwno-genesis (or 

 alternation of generations) in tlie animal kingdom, is another element of 

 difficulty in the solution of this question. Such investigations, however, 

 as those undertaken by the Xew York Commissioners conducted as they 

 have been in a truly scientific and philosophical spirit, must necessarily 

 result in throwing light upon the subject and be ultimately crowned with 

 success. 



My collection of pha'^nogamous plants comprises about one hundred 

 and seventy species. Of these about two-thirds consist of graminese 

 and cyperaceffi, comprising the grasses proper and the rushes, sedges, 

 and reeds, and water grasses. I am now engaged in their examination, 

 and will furnish to the Agricultural Department a full series. Besides 

 these, I collected such lichens and mosses as I could readily obtain, 

 specimens of which will also be prepared for the department.
