Berlin June 7, 1869 



My daer Dr. Weber 



Kere I have been already 8 days in Berlin f exploring all 

 9.roi;nd,a^d finally I receive^ the Long: awaited seeds of Agave virginl - 

 ana , which I had promised Mr. Guedeney. Thus, I can write to you too, 

 as promised long ago. 



I also received a letter frora Gen. Jacoby.in which he teils 

 me that he has been transferred fron Breslau to Posen and that he will 

 bring his entire collection of Cacti and Afravae there. 



I told you, that I left several south-american and other 

 cacti here at Haseloff. A number of them have died.but two cylindrical 

 Opuntias are doinß: f ine, and also a Echlnocereus . Further, ar üpuntia 

 from Utah, which I cultivated already for 8 years, and which I named 

 0. Utahensis , prospers quite welli it is a very neat plant. Of this 

 somethlng could be shipped soon, the others would have to be propaga- 

 ted first in a regulär manner. Get In contact about this wlth Dr. Posei- 

 gen to whom I have trusted the care of these plant s, because Mr. 

 Haseloff is quite ailing and can hardly take care. Otherwise I have 

 not seen anything worth mentioning of cacti, but continued of oourse,- 

 to take notes about everything that comes betone me. 



I also kept thinking about Mamillarla nicromeris and became 

 only confirmed. in the view,that one must not separate it from t'^e Ma- 

 mlllariae , at least /a^^et^^jio^.l would like however, as I indicated 

 to you already in Paris, to constitute a separate section for it.. 



I would like to arrange the Maml llariae as follows.
