Most Honored Sir Dbctor 1 



Professor Alex. Braun was kind enough,to present to me two of 



your letters, addressed to hinras welll as enclosed samples of ameri- 



can ^fallitriche for viewing; the most interesting notations, which IT 



found therein v ,make me wisltf eagerly,to turn to you directly.. Primar- 



ly I r would like to get your permission, to let me use those notations,,

 Nütt. from Texas 



peploides ,| probably determined from original samples,. are identical 

 to my C. Drummondi ♦ . Further, that your american C*l autumnali s 

 from the St. Lawrence a - troam is identical with our europaean». 



As A. Braun told me, you will have reeeived in the meantime 

 his <1 defleja from Brazil, and, though you may have formed al - 

 ready an opinionr about the particular forms,I nevertheless take thp 

 liberty,to present my view in this matter. .Your small sample of Cf.
