Mr. G. E. Davenport has described another form of Nephro- 

 dium spinulosum in Rhodora for February. It was found in 

 Concord, Massachusetts, and has been named Concordianum. It 

 is described as a large plant with tripinnate fronds, whose seg- 

 ments are distinct, narrowly angular and aculeate. Mr. Daven- 

 port regards it as having arisen as a "spore variation."
