Geneva, April 10, 1860 
My dear Sir and Friend, 
| hope that you will have received my letter and the fragments of the Euphorbia that | 
sent you for you to examine.Today | write worrying that the Euphorbia that you had 
wanted to send me in your letter of December 8, could have been lost, because | have 
never received them. This would be a great misfortune for me. Please tell me to whom | 
should complain about this incident. Since | have decided to write to you | have come 
right along in the work | began and will now have to go to the herbarium in Paris and 
London. Because of this |! will have to depart at the beginning of the month, but the 
circumstances in which Switzerland is in relation to Napoleon, impede me from traveling 
until the question is settled on one side or on the other. Three weeks ago | saw all the 
Euphorbia in the herbarium of Berlin and was impressed at the correciness of your 
observations. There will be many comments on the work of Klotsch. Frequently the 
same species is found but with different names and sometimes the genders according to 
Klotsh are different!. | agree with your way of seeing the synonyms of the Euphorbia 
adenoptera Bertol. 
| now believe that at the Berlin Herbarium | saw what ! will include in my publication, 
about the new species of Euphorbia that | had described in the Prodromus also studied 
by the Baron Grinbach or other Euphorbiaists or there similars. | will send you other 
brochures as soon as they are ready. 
| received the fragments of the Euphorbia from ?? who identified most of the species. 
Through the kindness of our friend Gray | also received the leaves of the Euphorbia. 
There seem to be Euphorbia that | still do not know! E. Arizonica, bifurcata, burbelleta, 
colorata, multicorolis, etc. 
In regards this, in one of your letters you tell me about the E. phenosperma Schulti (E. 
chloridiana). 1 could not find samples among my plants. | believe they are trilobular like 
most part of the species. 
Mr. Klotsh wrote me that his work in regards the Euphorbia has been printed, even 
though it was difficult to produce. 
f you should have something to send me please do it through New York with Charles 
Vignier in The Havre. He is my correspondent and everythings arrives happily. 
Mr. Reuter sends his best wishes, and from me, as always receive my most devout 
sentiments of affection. 
E. Boissier 
M. de Candolle is still in Italy where he has spent the winter, but he will be arriving soon 
to study the Quercus that he will include in the prodromus.
