VI PREPACK. 



Prof. William T. Fcay, M.D., and Prof. Thomas G. Tond, both of 

 Savannah, Ga., have sent almost the entire Flora of that State, with 

 copious original notes and observations, such as result only from tho 

 most extensive and accurate investigation. 



Miss Sarah Keen of Bainbridge, Ga. (now of Mariana, Fla.), has also 

 sent an herbarium of beautiful specimens prepared by her own and her 

 sister's hands. To her, as well as to the gentlemen last mentioned, the 

 author is also indebted for every kind hospitality and encouragement 

 during a protracted herborizing tour along our southern coasts. 



Mr. William Wright of Bainbridge, and Prof. N. II. Stuart of Quincy, 

 Florida (since dsee ised), also contributed to the consummation of our 

 work by many facilities afforded us in our laborious researches in their 

 respective precincts, and by the shelter of their hospitable mansions. 



To Rev. Dr. Curtis of Hillsborough, N. C., and to Rev. Dr. BacU- 

 man of Charleston, S. C, we arc indebted for the free use of their very 

 complete herbaria, during our sojourn in their respective cities ; and 

 Mr. S. B. Buckley, recently of Yellow Springs, Ohio, has afforded us 

 similar facilities through his rich collection. 



Dr. Couscns generously supplied us with the plants of the State of 

 Jowa. His name often appears in our pages. 



Dr. George Engelmann, of St. Louis, has also favored us with the 

 free use of his admirable monograph of the genus Cuscuta, and with 

 many important notes in MS. on other difficult genera in our Flora, 

 especially on the Euphorbiaccae. Our entire collection of specimens 

 belonging to this Order was, by his kind permission, submitted to his 

 inspection and determination. 



The Rev. Chester Dewey, D.D., of Rochester, N. Y., the venerable 

 pioneer in American Caricography, has placed us and our readers un- 

 der renewed obligations by additional contributions to the genus Ca- 

 rex, rendering it complete for the extended territory of our present 

 Flora. 



Communications containing specimens, critical notices or corrections, 

 or soliciting information, will always, as heretofore, be acceptable.
