Berlin Oct. 18, 1875 



Most hono^ed Friend ! 



Your letter of August 3 ß-ave ne .erreat pleasure, and I regret, 

 that only now I get to it, to anwer it thoroughly. I hope, that you 

 reeeived the few words Witten on a postal card immediately after re- 

 ceipt of your letter.. I should really be mad at you, be cause I see,- 

 that my last, long letter to you was dated January 30,1871, and 

 since then I reeeived neither news nor seeds nor plants frora you.. 

 Four one half years is a lon^r time at our age.- I shall now 

 ans wer your questions as far as possible»- As to Cer . tuberosus , 

 of who f se truly terminally posltioned f Towers Prof. Braun bad the 

 kindness to eonvlnee hinseif at ray home.I can now teil you, that 

 the very sarae two speciraens flowered this year almost e^ti^ely side- 

 ways, and I believe, to know the cause now. In lt f s homeland I saw 

 it flowering in many thousands of speeimens, and by far the nost 

 flowers were terminal. He^e, in Berlin, it did not want to bloom 

 at all at first; after I had grafted it on Peireskia , it developed 

 sometimes Single flowers, which howetoer were mostly side-positioned. 

 Only now, that I have a llght, airy gardenydoes it flower properly. 

 Düring Summer it Stands in the open, and in Fall it comes lnto the 

 glasshouse* It seems now, that, if the growth of the shoots has cone 

 to a connlete stand still; it flowers sideways, meaning, still always 

 close to the tip; if , however, the shoots contlnue to grow in the 

 house, then it flowers terminally. Flowering time is March a nd April. 



I will add he^e an interesting Observation. I use as base for 

 grafting for all klnds of cacti very frequently Peireskia acule/ta ,. 

 which is excellently suited for this. This one has in every areole,. 

 below the leaf, 2 snall , curved spines. If an other cactus is graf - 

 ted, so that the Peireskia cannot grow any further, the stem nor 

 mally loses the spines over the years and be comes entirely snooth.
