EXCLUDED SPECIES. 



CYCLAMEN EUROPIUM. Linn. 



This has been reported as occurring in Britain, but it seems doubtful 

 if C. hederifoliura has not been mistaken for it. 



LYSIMACHIA QU ADRIPOLIU M. Linn. 



I have this North American species under the name of L. punctata, 

 collected by the late Mr. J. Storey in Heaton Dene, near Newcastle, 

 Northumbei'land, with the remark that it is abundant but not 

 indigenous.
