TO GEORGE ENGELMANN. 
New York, November 30, 1841. 
Dear Doctor, — Don’t hesitate about sending me 
anything for fear I may already have it. Very many 
plants pass through my hands while I am describing, 
but my own herbarium is not very rich; and dupli- 
cates will not oppress me. Mr. Carey does not keep 
European plants except those identical, or supposed 
identical, with North American species. Browne, 
however, does, and I dare say would be glad to have 
any you can give him. They are the gentlemen men- 
tioned in the “ Flora.” .. . 
Eupatorium Engelmannianum, sp. nov. Am. Bor., 
semina misit Engelmann. Can this be it, think 
you? If so pray help me to it; and to anything else 
you can, as I mean to give addenda et corrigenda to 
the Composite at the end of the order, if I ever get 
through this formidable job. No wonder seven years’ 
labor at them ruined De Candolle’s health. You know 
he is dead? He died the 9th or 10th of September 
Idet. 2. . 
I send you my article in the January number of 
“ Silliman’s Journal” with a little one by Sullivant, 
—by mail. I am extremely busy this winter, but I 
hope always to answer your letters promptly, and to 
attend to your desires as well as I can, whence I beg 
you to continue your useful correspondence.

It is not a great while since I got all the copy 
ready for the number of the “ Flora” now printing, 
— during which I could do little else. Immediately 
this was done I completed an arrangement with my 
publishers for preparing a handsomely got up Intro-
