I. auricoma P)atsch. listed by Lea, is regarded by Fries as 

 a variety of I. descissa. Abjrgan, who worked in the same region 

 as Lea. did not collect it. Tt is possible tliat Lea's plants were 

 incorrectly determined. 1 he s])ecies is omitted from the list. 



It is wortliy of note here that Peck enumerates 39 species 

 for the state of Xew York. ()f the 9 species reported from Ohio 

 only 5 occur in Peck's list. It is remarkable that such a dis- 

 parity should occur in states no more widely separated. It is 

 probable, however, that further study of Ohio plants will add' 

 a number of species to the Ohio list.
