 My Dear Friend 


 Our last letters crossed. Yours of the 
 8th reaching me about the time my last reached 
 you, I suppose.


 I am surprised that my lecture 
 did not come to hand; but am as sure as may 
 be that it was at Wiley & Putnams when Hastings 
 called. I begged Wiley to take special care of 
 it. It laid them so long as to be forgotten. Immediately 
 on receipt of yours I wrote to Wiley 
 calling his attention to it, and begging him, if he had 
 it to drop you a line 


 I mailed the N. Amer. Review on Saturday last. 
 I have a pamphlet for you from Fischer, to be sent when
 I got the drawing of Illicium from Sprague, who has 
 disappointed me, but I think he will come up from Hingham 
 to-day or to-morrow. If you want the drawings we 
 spoke of it is very important that you should come to 
 a conclusion and let us know. 


 Are the pods of Spirolobium (good name, if char. [character] hold)
 twisted thus except when old? Of course I want Anemopsis.


 As to Platanus you know there is a Western 
 spec. [species] P. [crossed out: occidentalis] Nutt. [Nuttall] [added: referred by Hooker to P. occidentalis] (Hook. [Hooker] & Am. Bot. [American Botanist] Buckley &c.)
 [crossed out: But Bentham in Voyage Sulphur separates the
 Californian ones] but which Nuttall has figured 
 under some name, if forget what, in Audubon.
 I have seen his specimens, and remember the long strings 
 of balls. But Bentham (in Voy. [Voyage of the] Sulfur) has also just
 described it as a new species P. [Platanus] Californicus, not knowing 
 of Nuttall's. You shall have Voy [Voyage of the] Sulfur 
 & Benth. Eriog. [Bentham's On the Eriogoneae] by and by. But I need both for 
 a little in studying Plantae Lindheimerianae, which I go 
 at now. You sent me [Scrulph.?] & Polemon, which I
 sent to Bentham, as directed.
