Flora of Delaware and the Eastern Shore 



Places. Since three states are involved, names of places are 

 frequently duplicated. For this reason, as well as to facilitate 

 reference to maps, names of localities cited in the text are usually 

 followed by the abbreviations (in parentheses) of the counties in 

 which they are situated. 



Herbaria. When individual collections of any species are cited, 

 the herbaria in which the specimens have been deposited are indi- 

 cated in parentheses immediately after the date of collection. 

 The following abbreviations are used : 



A = Academy of Natural Sciences of Philadelphia. 



D = Society of Natural History of Delaware, at Wilmington 



(Canby and E. Tatnall herbaria). 

 G = Gray Herbarium, Harvard University. 

 P = University of Pennsylvania. 

 T = Herbarium of R. R. Tatnall, Wilmington. 

 U = United States National Herbarium. 

 UD = University of Delaware, Newark. 



Lists of authors of scientific names of plants are to be found in 

 most of the manuals, and none is given here. The list in Bailey: 

 "Manual of Cultivated Plants" (1924), and that in Rehder: "Man- 

 ual of Cultivated Trees and Shrubs" (1940), are especially satis- 

 factory. In the present List, "Michaux" is abbreviated as "Mx." 

 instead of the usual "Michx." 



The following collectors of Peninsula plants are among those 

 most frequently cited in the Annotated List, often by surname only.
