 Dear Doctor,


 I found last evening the parts of London 
 Journal of Botany I wanted in town, and have the 
 satisfaction to inform you that the Romneya is 
 not your Papaveraceous genus at all, nor Dithraea
 your queer Crucifera. Romneya is a tall, glabrous 
 Poppy-looking plant, pretty close to Poppy except
 in the slender erect and unconnected stigmata. 


 You can therefore sketch your generic characters 
 without reference to Harvey. 


 Friday morning. 


 I did not hear from you [crossed out: this] yesterday, as 
 I had hoped. [added:  You still owe me a letter.] I have written to Sprague, asking 
 him to come up, but have not heard from him.
 I feel quite uncertain, now what you would have 
 me do, whether to retain the Fremont plants you 
 sent me, and have Sprague make drawings of
 the Papav. [Papaver] &c. when he comes, or to send them 
 right back to New York. Your expected letter must 
 decide that. I suppose you only want 
 to mention, in a sort of narration report, the new 
 genera, as well as some of the most curious species. 
 The Crucif. [Crucifera] & Papav. [Papaver] could be mentioned as new 
 genera, by the name you may propose, and their
