Dear Dr. Kennedy :- 



I have looked o*»r your 1 plants from Wil^Oiaghby re- 

 cently sent me. The viola is what I called v. venustula in my Hho- 

 dora paper, but I fear it is hardly distinct from V. af finis , LeConte, 

 or What they are calling that in the Middle States. This I suspected 

 when I wrote the article; and since seeing these plants at washing- 

 ton, my suspicions have grown into 8 conviction .Pending a discussion 



of this subject, I have retained V. venustula in the "supplementa- 

 ry list," adding "haroly distinct from v. af finis, LeOonte." 



The Potamogeton I should call P . he t erophy llus ; the submerged 

 leaves are not broad enough for P. Zizii , anc'i in other slight fea- 

 tures it fails to correspond to a specimen of P. Ztzi i that I have 

 from Morong . The two species are indeed *eyy close both in fruit 

 and in foliage. 



Your letter of Saturday came this morning. I sent you all the 

 specimens that I had of Oalamagrostis , for your opinion of them. 

 I confess I have improperly used my exchange labels on some of the 

 specimens placed in my own herbarium. But I shall be very glad to 

 have you Keep all but the plants collected by Prof. Jones. Mr Rates 

 was apiost careless collector, and used to send me a lot of unnamed 

 material without date or station. I occasionally mo\mted some of 

 the rarer things. Kis oalamagrostis was probably from Filloughby. 



I looked for you after the meeting April 1st , and was sorry 

 to have seen so little of you. I am glad to know that my conclusions 

 r yarding violets commended themselves to you. I have done some hard 

 work on this problem, and hope to get to the bottom ,^efor a I stop. 



Yours faithfully,
