seen the specimen and it should be referred to Cheilanthes lanosa (Michx.) 

 Watt. Cheilanthes tomentosa has its range south of our area. 

 Va. to Ga., westw. to Tex., Ariz., and Mex. 



11. Adiantum pedatum var. aleuticum Rupr. This variety of the 

 maidenhair fern was reported by Behrens (Proc. Indiana Acad. Sci. 37: 

 377. 1928) from Turkey Run State Park, Parke County. He writes: 

 "Common maidenhair fern. The Maidenhair is distributed throughout the 

 park in the uplands. It is one of the most common of the ferns found in 

 Turkey Run." When the range of this fern is considered this report 

 becomes absurd. 



Alaska southw. in the high Sierra Mts. to Nev., Que., and n. N. E. 



12. Marsilea quadrifolia L. Pepperwort. Grimes, in 1911, reported 

 this species from an old mill pond on the south side of the Vandalia Rail- 

 road in Greencastle, Putnam County. He remarks that it was fast dis- 

 appearing due to drainage and subsequent encroaching of vegetation. He 

 adds that it was first detected in 1904 by Dr. Banker. A specimen col- 

 lected by Banker, dated October 11, 1905, is in the herbarium of DePauw 

 University and bears the following information : "Transplanted from Con- 

 necticut to Ithaca, N. Y. by W. R. Dudley ; from there to Columbus, Ohio, 

 by W. A. Kellerman; and to here in 1903 by Mel T. Cook." In 1937 I 

 searched for it but failed to find it. It has probably disappeared. 



Nat. of Eu. and Asia. 



13. Equisetum sylvaticum L. Wood Horsetail. Reported from Dear- 

 born County by Collins. In Coulter's Catalogue it was placed in a list for 

 which there were no verifying specimens. Since this species is more 

 northern in its distribution and there is no confirming specimen, it is 

 excluded. 



Schaffner says it is found in the northern part of the North Temperate 

 Zone. 



14. Equisetum pratense L. Meadow Horsetail. This species was re- 

 ported from St. Joseph County by McDonald. I have seen the specimen 

 and I refer it to Equisetum arvense L. 



N. S., Que. to Alaska., southw. to N. J., Iowa, and Colo. ; also in Eurasia. 



15. Lycopodium clavatum L. Reported from Lake County by Ball, and 

 Pepoon includes it in his "Flora of the Chicago Region" and says : "Found 

 near Miller, Ind., by Higley." It is not included in the Higley & Raddin 

 Flora. Peattie, in his "Flora of the Indiana Dunes," says: "Perhaps an 

 error." Buhl (Amer. Midland Nat. 16: 250. 1935) adds: "Northern in 

 range, reports in error." Since confirming specimens are lacking, the 

 species is dropped from our flora. 



Lab. to Alaska, southw. to N. C, Mich., and Wash. ; also in Eurasia and 

 tropical Amer. 



16. Lycopodium complanatum L. Groundcedar. This species has 

 been reported from the area about Lake Michigan and from Monroe and 

 Putnam Counties. Since the distribution of this species, as now understood,
