Excluded Species 1019 



sandy soil. Usually found on black and white oak slopes, although I found 

 several specimens in a moist, level, sandy woods along Pigeon River in 

 Lagrange County. A glandular variety of this species has been described, 

 but all of our specimens are glandless. 



N. S. and cent. Maine to Mich., southw. to Ga. and Ala. 



7. Hieracium scabrum Michx. (For described varieties of this species 

 see Rhodora 16: 182-183. 1914.) Map 2243. Infrequent throughout the 

 area indicated on the map. This species also prefers slightly acid and 

 sandy soil. It is usually found in dry soil on slopes with black and white 

 oak and rarely on sandy flats with the same associates. Besides the counties 

 shown on the map, it has been reported from Fayette, Parke, Tippecanoe, 

 and White Counties. 



N. S. to Minn., southw. to Ga., Iowa, Nebr., and Kans. 



EXCLUDED SPECIES. 



This list contains native species reported from Indiana of which no 

 specimen could be found to confirm the report. Reports of foreign trees, 

 shrubs, and plants found in yards, cemeteries, parks, and gardens have 

 been excluded. This list contains many foreign species that have been 

 reported without data to confirm the fact that they have become estab- 

 lished and have become a part of our flora. Among these are many 

 ornamental plants that have escaped to or have been thrown into streets and 

 alleys and have not become a part of our flora. It contains, also, many 

 incorrect determinations which are explained in the text. 



1. Lygodium palmatum (Bernh.) Sw. This fern was reported by Col- 

 lett in Rept. Indiana Geol. Surv. 5: 256. 1874. This report was changed 

 by the same author to Camptosorus rhizophyllus (L.) Link in Rept. Indiana 

 Geol. Surv. 7: 400. 1876. 



2. Dryopteris Linnaeana C. Chr. (Phegopteris Dryopteris (L.) Fee and 

 Dryopteris Dryopteris (L.) Britt.) Oakfern. This species was reported 

 from Allen County upon the authority of J. A. Sanford by the editors of the 

 Botanical Gazette in a supplement to the Flora of Indiana, published in 

 April, 1882. Since this is our only report and there is no verifying speci- 

 men, the species is excluded. 



Newf. to Alaska, southw. to Va., Kans., Colo., and Oreg. 



3. Dryopteris Phegopteris (L.) C. Chr. (Phegopteris polypodioides 

 Fee.) Narrow Beechfern. This fern was first reported from La Porte 

 County in 1873 by Babcock. It was next reported from Putnam County by 

 Coulter on the authority of Underwood. Pepoon says in his "Flora of the 

 Chicago Region" that it is abundant in Porter County north of Port Chester. 

 Behrens reported it as frequent throughout Turkey Run State Park, Parke 

 County. I searched the Babcock herbarium for it in 1929 but I could 

 not find a specimen. I am excluding it because I believe that depauperate 

 forms of Dryopteris hexagonoptera have been mistaken for it. 



Newf. to Alaska, southw. to N. Y., Va., Wis., Iowa, and Wash.; also 

 in Eurasia.
