Dear Sir: 



Enclosed please find your list with a few suggestions which 

 have Prof. Hitchcock's approval. I am wondering if Dr. Robinson 

 will insist on your making a "new combination" for P. sphaerocarpon 

 inf latum (Soribn. & Smith) Hi tchc y ^ since in the revision it is not 

 stated in what catagory this is . Perhaps it would be well to call 

 attention to the fact the P. anceps is not known from Hew England, 

 tlB Rhode Island of the Manual being an error apparently. If 

 anyone then has a specimen collected in Hew England this statement 

 would bring it to light. 



Yours respectfully, 



Assistant in Systematic Agrostology.
