This letter was sent to Elihu Hall, who sent it on to Engelmann. 
Dear Sir: 
I recently saw in the herbarium of Dr. Boissier in Geneva some of your 
Plantae Oregonenses of which/kas especially interested in the Juncus species. 
I, therefore, take the liberty to ask you whether you would be willing to sell 
or exchange these and other plants. Should the first be the case, please let 
me know your conditions. 
Sincerely, 
your devoted 
Prof. Dr. Buchenau 
Some of the plants from Illincis, I own through the kindness of my friend 
Dr. Engelmann, St. Louis.
