 Dear Sir: 



Your letters of February 16 and 19 have been received, and 



the package came this looming. Thank you for the specimens. 

 Your Cape Breton Agrostis is A. alba var. mari tiroa(Lam) Meyer. 

 This is a coast variety, extending from Newfoundland to De lav/are . 



Panicum xanthophysum is from the only place I have ever 

 seen this handsome species growing. Mr. Knowlton, who is also 

 a friend of hers, doubtless collected this as I did while on a 

 visit to Miss Eaton. 



Panicum luci.dum in the autumnal phase may be looked for 

 from the latter half of August until frost. The terminal part 

 of the primary culm is likely to have fallen. In its autumnal 

 form P. lucidum is unlike any other northern Panicum. Unless 

 sought for it may be overlooked because all the culms stretch 

 out on the ground, running under brush and leaves , It is a 

 beautiful glossy thing and quite worth the trouble of disen- 

 tangling from other vegetetion. 



Yours respectfully, 



Assistant in Systematic Agrostology.
