ates 40 native species of ferns and 13 allies besides a few 

 introduced" species. Other botanists who have con- 

 tributed to our knowledge of Georgia pteridophytes by 

 their explorations are Dr. Chapman, who did some 

 work many years ago in Floyd County, in the Pal- 

 aeozoic region, and discovered Isoctcs Engelmanni 

 Georgiana there ; Mr. Canby, who discovered Isoetes Me- 

 lanospora on Stone Mountain ; Prof. Underwood, who 

 has collected around Stone Mountain and Tallulah Falls ; 

 Dr. Small, who has probably explored the mountains of 

 Northeast Georgia more than any other botanist; Mr. C. 

 L Boynton of the Biltmore Herbarium, whose collections 

 of Georgia ferns have been made principally from Stone 

 Mountain to the northwest corner of the State ; Prof. A. 

 Ruth of Knoxville, Tenn., whose work in Georgia has 

 been principally confined to Lookout Mountain and vicin- 

 ity, in the Palaeozoic region; Mr. Percy Wilson, who 

 accompanied me in the northwestern quarter of the State 

 in July and August, 1900, and paid special attention to 

 ferns : Messrs. Pollard and Maxon of the U. S. National 

 Herbarium, who traveled together through the western 

 half of the State a few days in August. 1900 ; Mr. A. B. 

 Seymour, who collected cryptogams in the vicinity of Tal- 

 lulah Falls in 1901 ; Mr. B. D. Gilbert, who published 

 some notes on ferns in the vicinity of Savannah in this 

 journal for July, 1902; and Mrs. A. P. Taylor of Thom- 

 asville, some of whose finds have already been mentioned 

 in these columns. I have compared notes with most of 

 these botanists either in person or by correspondence, 

 or both. 



Except where otherwise specified. I am personally 

 responsible for all the stations mentioned in the follow- 

 ing list. The sequence of genera and species is that of 

 Maxoivs list (Proc U. S. Xat. Mus. 23:619-651. May 

 4, 1901). The nomenclature has been revised by the 

 editor to conform as nearly as possible to that of the 

 other State fern floras already published. .
