          Dear Doctor


 Our last letters crossed, and I believe 
 I have already replied to some of the points in yours of 2nd Oct.
 On many others, unfortunately, I have no available information 
 to give. I know nothing definitely of Poplars. My
 Herbaria-notes are now packed up until my study shall 
 be put in order, but I fear they contain nothing that will 
 essentially aid you. I have somewhere I note about 
 Populus Graeca given me by Webb, who somehow ascertained
 that it was of American origin, but I suppose that would 
 not much concern you. I certainly wish that the 
 Clintonia of Raf. [Rafinesque] could be avoided. But I know not 
 what should be done with the old genus Convallaria. 
 Nothing more to say about Orchid. [Orchidaceae] or (N.Y.) Melanthaciae. 
 Greene has been at Norwich (Conn. [Connecticut]) since your 
 letter was received, but he has probably returned by this 
 time. When I see him (which is not like to be 
 until Saturday) I will ask for his Lindl. Orchid. gen. &c. [The genera and species of orchidaceous plants, by John Lindley]
 which I have no doubt he will willingly lend you.
 It is a meagre book. You can judge as well as me as to what of Fremont's plants should be sent to Benth. [Bentham]
 certainly Scrophulariaceae. I have already told you that 
 I would like to see the Compositae. Thus
