Acknowledgement is due many who have kindly made determinations of ma-

REPRINT NOTICE 



The Bureau of Sport Fisheries and Wildlife is grateful to the U.S. Public 

 Health Service for permission to reprint its Bulletin No. 286, "A Guide and Key 

 to the Aquatic Plants of the 'Southeastern United States." When issued in 

 1944, this publication was very well received and the supply is now exhausted. 

 It has been available only in libraries of some State and Federal agencies, uni- 

 versities, and from private workers fortunate in having a copy in their possession. 

 Because of its continued usefulness, reprinting was arranged without change or 

 alteration to the original. The Bulletin will no doubt continue to serve biologists 

 of the Southeastern States concerned with aciuatic habitats for many years to 

 come.
