428 HARPER: VEGETATION OF THE COASTAL PLAIN 
Nearly 37 per cent. are confined to the coastal plain, as far 
as known, while 32 per cent. extend into the adjacent Piedmont 
region (several of them even to the mountains), but not into the 
glaciated region. About 4.5 per cent are common to the glaciated 
region and coastal plain and not known elsewhere, while a little 
over 26 per cent. are rather widely distributed in Eastern North 
America. About 6 per cent. (including some of each of the three 
groups just mentioned) are supposed to occur also in the West 
Indies, but none are unquestionably native in the Old World. 
Notes on the distribution of certain species of particular in- 
terest observed on this trip will appear in a subsequent paper.
