Very esteemed Friend I 



Yo^i n^de ne very happy by your substantial, friendly coraraunica- 

 tiorrof Dec. 12 of the precedinpc year, and would have answered long 

 a^ro , had I not beer occupied|by an interesting, official Job, the 

 experiences of artillery in the war in the past year jf or a long tiraejf. 



Nbw I have again a little air, and will not delay to reply to 

 your friendly renarks and questions.. 



I Cactr 



1. E. papillosus If I an not mi staken, I sent along a fruit of this 

 species to you. You consider this a larger species of E. Berlandieri" . 

 If, however, one compares the Illustration and descriptiorr of the fruit 

 of E» Berl« . with the fruit of E. papil. , these two are so completely dif- 

 fe^ent fron each other, that I would not s^are your view. Also, the 

 entire growth of these plants is dif^erent. While E»Berlandierl oreeps 

 with root-connected nenbers along the soll:, and , then f . produces wlth 

 these nenbers vertically standing sprouts, the nenbers of E.pap .are 

 never rising ( ascendented ) and produce nuch fewer sprouts..
