The herbaria consulted have been the Gray Herbarium, and those 

 of the New York Botanical Garden, the University of Nebraska, 

 and the Charleston Museum. Citations of specimens in the 

 latter are marked (H), and refer chiefly to Ravenel's herbarium 

 from the vicinity of the Santee Canal, upon which his Catalogue 

 is based, and to specimens of my own collecting within the last 

 four years. A few specimens are from Francis Peyre Porcher. 



Further records are from the survey, based on my personal 

 observations. 



The number of species listed is twenty-nine, seven of which are 

 from Bachman's Catalogue, unsubstantiated by specimens and 

 probably erroneous. Six species which the manuals credit to 

 South Carolina should be looked for in the coast region, namely, 

 Ophioglossum vulgatum L., Botrychium hiternatum (Lam.) Un- 

 derw., B. obliquum Muhl., Asplenium dentatum L., Lycopodium 

 luddulum Michx., and L. chapmanii Underw. 



The nomenclature followed is that of the first edition of Small's 

 Flora of the Southeastern United States. 



I wish to express my thanks to Miss Margaret Slosson and Dr. 

 B. L. Robinson. Dr. Robinson has most generously furnished 

 me with data for over six hundred specimens of South Carolina 

 plants in the Gray Herbarium. 



Ophioglossum crotalophoroides Walt. Adder 's-tongue. Light 

 soil in pine woods. 



Records. Bachman: Charleston. Ravenel: Santee Canal (H). 



Botrychium virginianum (L.) Sw. Rattlesnake Fern. This 

 species is probably common but the older herbaria have preserved 

 no specimens of it. Bachman lists it for Charleston and Ravenel 

 doubtless refers to it as one of his two species of Botrychium, 

 Ophioglossum crotalophoroides from his herbarium being the other. 

 Miss Mabel Webber and I found it fairly common at Otranto, 

 in low mixed woods bordering the swamp to the west of the rail- 

 road. On April 27, 1913, the spores had fallen.
