1020 Excluded Species 



4. Dryopteris simulata Davenport. {Aspidium simulation Daven- 

 port.) Reported from the dune area by Peattie and by Pepoon. Fassett 

 (Rhodora 35 : 200. 1933) says that the specimen upon which these records 

 are based is Dryopteris Thelypteris var. pubescens. This species is not 

 found west of the Allegheny Mountains. 



Maine, Vt. to Md. 



5. Dryopteris Filix-mas (L.) Schott. {Aspidium Filix-mas (L.) Sw.) 

 Male Fern. There are three reports of this fern from Jefferson County, 

 and I reported it from Wells County. I now refer the Wells County speci- 

 men to Dryopteris Goldiana and, no doubt, the Jefferson County reports 

 should be referred to some other species, since the range of Dryopteris 

 Filix-mas does not extend to our area. 



Newf., N. S., n. Vt., Lake Huron, Lake Superior, N. Dak. to Ariz., and 

 northw. 



6. Dryopteris Clintoniana X spinulosa Benedict. Reported by Nieuw- 

 land (Amer. Midland Nat. 2: 277. 1912) from La Porte County, based 

 upon Deam's specimen no. 8751. I am now referring this specimen to 

 Dryopteris spinulosa var. fructuosa (Gilbert) Trudell. 



7. Dryopteris spinulosa var. Americana (Fisch.) Fern. {Aspidium 

 spinulosum var. dilatatum f. anadenium Rob. and Dryopteris dilatata 

 (Hoffm.) Gray.) This form was reported in 1912 from Porter County by 

 Hill and from Parke County in 1928 by Behrens. Since the range is to the 

 north of Indiana and I have not seen a specimen, I am excluding it. 



Lab. to B. C, southw. to the uplands of N. E., Pa., Mich., Idaho, and 

 Oreg. and in the mts. to N. C. and Tenn. 



8. Dryopteris Thelypteris (L.) Gray. This species is restricted 

 to Europe, western Siberia, eastern Asia, southward to the Himalayas and 

 southern China. Fernald has recently shown that the American marsh 

 shield fern is distinct from the typical species. The Indiana reports for the 

 marsh shield fern have been under several names but they should now 

 all be referred to Dryopteris Thelypteris var. pubescens (Lawson) A. R. 

 Prince. 



9. Athyrium Filix-femina (L.) Roth. This species is now regarded 

 as belonging to Europe and probably western North America. All of the 

 many reports of it from Indiana should be referred to Athyrium asplen- 

 ioides and Athyrium angustum and its forms. For a discussion of the Lady 

 Ferns see Butters' treatment (Rhodora 19: 170-207. 1917). 



Specimens have been reported bearing the following names : Asplenium 

 Filix-femina var. angustum Moore, Asplenium Filix-femina fissidens 

 Doell, Asplenium Filix-femina var. Michauxii Mett., and Asplenium Filix- 

 femina ovatum Roth. The authors have not cited specimens, and, since 

 they cannot be traced in order to be identified, these reports are valueless 

 and should be dropped. 



10. Cheilanthes tomentosa Link. Woolly Lipfern. Reported from 

 Martin County by Craw (Butler Univ. Bot. Studies 2: 160. 1932). I have
