Somerset and Worcester Counties, Maryland, and still more so 

 in the two peninsula counties of Virginia. 



Polygala ramosa Ell. Noticed only once, and that in South- 

 ampton County, Virginia. (Several southern pine-barren plants 

 seem to have their northern limits in this same general region, a 

 little west of Dismal Swamp.) 



Ilex opaca Ait. First noticed a little south of Bloxom, 

 Accomac County, Virginia, and last about seven miles east of 

 Emporia. In the " manual region " this species seems to be 

 almost confined to the coastal plain, but farther south it is not so 

 restricted. 



Nymphaea advena Ait. Seen in most of the rivers and 

 estuaries of Delaware and Maryland, but not at all in Virginia. 

 Farther south it is not known in the coastal plain at all, its place 

 being taken by other species of the same genus. 



Magnolia virginiana L. First seen just north of Townsend, 

 Delaware, apparently just about where the Miocene begins. 

 Last seen in Brunswick County, Virginia, about 12 miles west 

 of Emporia. 



Castanea dentata (Marsh.) Borkh. Seen a few times between 

 Kirkwood and Wyoming, Delaware, stopping just about where 

 Pinus Tacda begins. Not seen elsewhere in the coastal plain on 

 this trip. 



Fagus gi'andifolia Ehrh. (Lately known as F. ferruginea, 

 atropiinicea, or Americana?) Not seen until after passing King's 

 Creek, Somerset County, Maryland, strange to say. Thence 

 rather common southward. Possibly this represents the var. 

 caroliniana (Loud.) Fernald & Rehder (Rhodora 9: 114. 

 1907), to which is assigned a decidedly more southern range 

 than the type. 



Myrica cerifera L. Abundant in the two peninsula counties 

 of Virginia, often attaining a height often or twelve feet. Com- 

 mon in the coastal plain west of Norfolk, to within about seven 

 miles of Emporia. 



Arundinaria iecta (Walt.) Muhl. Common in the coastal 

 plain west of Norfolk, and seen once in Mecklenburg County, 

 Virginia, fifty miles west of Emporia.
