Dear Sir: 



Your favor of Dec. 22 received. Please accept my best thanks 

 for Christmas wishes and Christmas card. 



We are glad that you have prepared a list of emendations to 

 the Pan i cum of the Manual in the light of the revision of the 

 genus , I shall go over your list carefully and return it in a few 

 days. Panic um auburne as described in the Manual includes P ._ al- 

 bemarlense and we at that time considered the two as a single species 

 At that time tlae northern specimens of P . albemarlense had not been 

 collected or were not in this herbarium. All the collections in 

 this region are of recent date and Mr. Bicknell f 8 specimens we only 

 obtained last yeajr. P. he lleri and P . _ ma l aca phy lluta had not been 

 confused with P._ scribnerianum but were not known from the manual 

 region at the time the manual was prepared. How P. anc eps came 

 came to be credited to Rhode Island we do not now know. A very few 

 additions of range were made by the editors to the manuscript as 

 prepared by Professor Hitchcock, but there is now no way of telling
