THE OTTAWA SPECIES OE ERIOPHORUM. 



Mr. M. L. Fernald's revision of the genus Eriphorum* has 

 made some changes necessary in the names of the species grow- 

 ing in the vicinity of Ottawa. It is probable that one or two 

 additional species or varieties may be found here and that col- 

 lectors may know what species have been already recorded the 

 following notes are published. The localities mentioned are those 

 known to the writer. The numbers and collector names are 

 those on the sheets in the herbarium of the Geological Survey.
