I There is some doubt at present as to what is the best interpretation of our Agro- 

 pyrons. AU available specimens have been submitted to Professor Scribner and the above 

 disposition meets his approval. A. caninum is a European species and when found in 

 eastern America is usually regarded as introduced. Apparently the Burlington plant 

 was native. A. caninoides was founded upon western types, and the Vermont plants 

 referred to this differ somewhat from the western plants. This disposition of them may 

 therefore be regarded as a provisional one, not altogether satisfactory. Of the new species 

 proposed Professor Scribner writes, Sept. ig, 1900, '' In regard to the Agropyron for which 

 I have proposed the name Novae- A ngliae, 1 must think it quite distinct from the A . lenerum 

 of the west, although it suggests that species somewhat in habit. It looks more like a 

 caespitose form of /I. repens. I believe it has been included under A. violaceum hy some 

 authors, but it certainly is distinct from that species, as represented in ourherbarium, from 

 northern Europe and from the Rocky Mountain region."
