and Roanoke Rivers there seem to be very few typical pine-barren 

 plants, or other species, which are not more common elsewhere. 

 It is not surprising therefore that comparatively little has been 

 published about this region (outside of Dismal Swamp and 

 vicinity) by botanists. 



About two years ago (Bull. Torrey Club 34 : 3 5 1-377) I men- 

 tioned the principal sources of information about the flora of that 

 part of the coastal plain between the James and Savannah Rivers. 

 That part between the James River and Chesapeake Bay is almost 

 never mentioned in botanical hterature, although John Clayton, 

 one of the pioneer botanists of Virginia, resided in that region 

 during most of the eighteenth century ; *and for the Delaware 

 peninsula, which is somewhat more accessible, there seem to be 

 at present less than a dozen " local floras." f 



Leaving out of consideration papers dealing only with seacoast 

 vegetation, (which has very little in common with that of the in- 

 terior, is governed by different laws of distribution, and is not 

 dependent on the presence of a coastal plain at all), the following 

 contain most of the available information about the flora of this 

 peninsula. The arrangement is chronological.

fin Britton's list of local floras (Ann. N. Y. Acad. Sci. 5: 237-300. 1890) 

 there are mentioned only two for Delaware (both for the vicinity of Wilmington), 

 two for Maryland (both for the vicinity of Baltimore), and four for Virginia (two of 

 these pre-Linnaean, another for the mountains in the southwestern part of the state, 

 and the fourth a very brief and bare list of plants from a very unnatural locality on the 

 coast).
