1076 Excluded Species 



along the R. R., July 15, 1899." I found it closely associated with Viola 

 affinis X sororia. I sent the specimen to A. Gershoy who says that he 

 does not know the species. I think it best to relegate this report to the 

 excluded species until the identity of the species is established beyond 

 a doubt. 



461. Rhexia MARIANA L. According to Fernald & Griscom (Rhodora 

 37: 169-173. 1935), the typical form of the species is a Coastal Plain plant 

 with a range from Massachusetts to Florida. 



462. Ludwigia hirtella Raf. This species was reported from Jefferson 

 County by Young and from White County by Heimlich. It belongs to the 

 pine barrens of the Atlantic coast. No doubt these authors confused some 

 hairy form of our native species with this species which is far from our 

 area. There is a specimen from Young's herbarium which is now at Indiana 

 University; it was collected by a Dr. Fretz in New Jersey, and evidently 

 was received in exchange. It is to be noted that in Indiana Ludwigia 

 alternifolia is always more or less pubescent and sometimes rather densely 

 so, although our manuals call it glabrous or nearly so. Prof. Heimlich may 

 have had at hand Ludwigia sphaerocarpa var. Deamii which is densely 

 pubescent and which at that time had not been reported for the state. 



Pine barrens, N. J. to Fla. and Tex. 



463. Ludwigia palustris (L.) Ell. According to Fernald & Griscom 

 (Rhodora 37: 176. 1935), the typical form of this species is found in 

 Europe and adjacent Asia and Africa and our form belongs to var. amcri- 

 cana (DC.) Fern. & Grisc. 



464. Ludwigia sphaerocarpa Ell. According to Fernald & Griscom 

 (Rhodora 37: 173-174. 1935) the typical form of this species is found on 

 the Coastal Plain from Rhode Island to Florida and Louisiana, and the 

 Indiana plant belongs to var. Deamii Fern. & Grisc. 



465. Ludwigia virgata Michx. Reported from Jefferson County by 

 Young. There is no specimen. 



Dry pine lands, N. C. to Fla. and La. 



466. Epilobium palustre L. I reported this species from Steuben and 

 Wells Counties (Proc. Indiana Acad. Sci. 1904: 220. 1905). I now refer 

 the specimens on which this report was made to Epilobium molle Torr. 

 This species was also reported from Hamilton County by Wilson, who says : 

 "Common." He does not report Epilobium coloratum which is our common 

 species and to which no doubt this report should be referred. It was re- 

 ported also from Steuben County by Bradner before our manuals made 

 the separation of our species definite. 



Newf. to Alaska, southw. to Mass., Ont., Lake Superior, Colo., and Wash. 



467. Oenothera grandiflora Ait. Reported from Putnam County by 

 Wilson, who found it along the Big Four Railroad ; from Kosciusko County 

 by Clark, who says: "A patch, probably of recent introduction, was found 

 in moist soil near Warsaw." I have seen no specimen but no doubt this
