Murrii.l: Polypokaceae of North Amkkica 227 



1832. Fries, Icon. //. 1S6. f. i) doubtless refers to the same 

 plant and I have a suspicion that Polystictiis arcticus Fr. is also a 

 synonym, since plants at Kew collected near Carlton in May, 



1858, are only grayish zonate forms of F. roseiis. The actual 

 types of P. arcticus I have not seen. 



A few of the collections examined are here listed : Finland 

 (Karsten), Canada (Macoun, Dearness), Maine (Miss White), New- 

 foundland (Waghorne ?), New Hampshire (Minns, Underwood), 

 Ohio (James), New Jersey (Flllis), Colorado (liethel, Pammell), 

 West Virginia (Nuttall), Washington (Piper), Florida (Calkins), 

 Nebraska (Kennedy), South Carolina (Ravenel). Alabama (Peters), 

 California (McClatchie), Connecticut (Underwood), Georgia (Un- 

 derwood).

Many other specimens have been examined, but the above- 

 mentioned are sufficient to show that the plant is of wide distribu- 

 tion. It is particularly injurious to various species of coniferous 

 trees.
