In the enumeration ofthe species. I saw several Xanthenes collected byyou in 

 Professor Braun 's herbarium and would very much like to see more examples 

 thereof. Unfortunately I do not have my manuscript here and can only write some 

 remarks from memory. A species collected as Xanthomanium( if I am not 

 mistaken) with the description that it grows 6 ft. tall, I think on the contrary must 

 be X. itunarium Europium; a Xanthium with large thorns designated as X, 

 mesocarpeumji believe to be a new species. It is closely similar to X. canadense 

 Hook. X. Mesocarpeum from Fl.de France does not occur in France America. 

 Usually it is X. italicum Moretti and maybe some other species. It would please 

 me very much ifyou or your friends would direct your undivided attention towards 

 Xanthium and the Ambrosiaceae. 



I am also interested in Agrimonia. Beyond that I very much wish for 

 Cyperaceae, Najadeae, Filices, Philadelphieae, and Nasturtium with ripe fruits. 



The garden here has obtained through purchase Ledebowich's Herbarium 

 with his own collected plants and duplicates.
