PREFACE. 



The Key is intended as an aid to students, beginning 

 field-work in Botany; in this second edition the plants 

 have been restricted mainly to those collected in Volusia 

 County. 



For more complete descriptions than those given here, 

 the student should consult: Dr. J. K. Small, Flora of the 

 South-eastern United States, publ. by the author, Bedford 

 Park, New York City; — Dr. A. W. Chapman, Flora of the 

 Southern United States, publ. by the American Book Com- 

 pany; — Dr. Bailey's Cyclopedia of American Horticul- 

 ture, publ. by the MacMillan Co. The arrangement of 

 the Families is that based upon Dr. Engler's Syllabus der 

 Pflanzenfamilien, and commonly accepted in present day 

 Botany. 



If two names are mentioned in the Key for the same 

 wild plant, the former will be found in Small's Flora, and 

 the latter (in parenthesis) in Chapman's Flora. 



The student's record of an analysis, either in the field 

 or in the laboratory, may be written in his note-book as 

 follows :
