the boundaries of the State. But considerably over 99% 

 of the coastal plain rocks are concealed by the superficial 

 sands and clays of the Lafayette and Columbia forma- 

 tions (approximately contemporaneous with the glacial 

 drift of the North), which form the bulk of the soils of 

 South Georgia. 



In the upper third of the coastal plain, over the Creta- 

 ceous and Eocene rocks, broad-leaved trees predominate, 

 sheltering many of the same species of ferns as are found 

 in Middle Georgia or even in the mountains ; and where 

 the underlying rocks are exposed (principally in the 

 vicinity of the Flint and Chattahoochee Rivers) limestone- 

 loving ferns are often abundant. In the remainder of 

 the coastal plain (known as the pine-barrens or wire- 

 grass country), open forests of long-leaf pine prevail, and 

 ferns are scarce. During a month spent by the writer in 

 the vicinity of Okefinokee Swamp and the neighboring 

 coast in 1902, only eleven species of pteridophytes were 

 noted, seven ferns and four Lycopodiums. 



But little has been written about the ferns of Georgia 

 outside of general works like Chapman's, Wood's and 

 Small's " Floras," Underwood's " Native Ferns," Daven- 

 port's " Comparative Tables," Small's " Altitudinal Dis- 

 tribution of Ferns," and Maxon's Fern List, and a num- 

 ber of papers in various botanical magazines. Daven- 

 port's " Comparative Tables," published in 1883, credits 

 14 ferns to Georgia, two of which probably have not 

 been collected in the State since Beyrich's time, seventy 

 years ago. 



In the Fern Bulletin for July, 1899, I mentioned 18 

 Georgia ferns and 6 other pteridophytes, mostly observed 

 by myself in Clarke County in Middle Georgia, and Sum- 

 ter County in South Georgia. Since that time I have 

 collected plants in most of the ife counties of the 

 State, in five different years, and have also had the 

 use of the U. S. National Herbarium and the library and 

 herbarium of Columbia University and of the New York 

 Botanical Garden, with the result that I can now more 

 than double my former list. The present paper enumer-
