Unf ortunately, the E chjjiocactl are very sparsely representetf- 

 though "a rougue gives alwavs nore tham he has 11 . 



Of Ce^. gjganteus I brought ^ little plants through the Winter,, 

 anci hope, that these will becone stronger during the Summer irrGod's 

 free Natur e and , then, , live through the coning Winter, With us, the 

 Winter was rather milder^ than severe. But at Christmas time we had 

 several daysup to - 12* degrees BT. »whereas later it came hardly to 

 5 (? E.D.) 



I was most surprised' about your newsr concerMng the den-ree of cold 

 which several cacti there sustained and an now eafrer to learn, how 

 these plants acted during the further course of Spring and Summer,, 

 a^d if the limpin^c lesson did not come later. There are Single exam- 

 ples of plants overwintering in the open with us too-; the known ca- 

 ses are however still too-^ unique.to permit General conclusions from 

 them, and the exaot circumstances, which permitted the overwintering 

 in the open, are not suf f iciently known.. 



If you get the Berlin Gardermewspapeir, you will have found irr 

 NO f s 11 - 15 some contributions to the science of cacti by me. The 

 described plantsjkre as individuals before me all new and stränge;; 

 thus I can not deternine, that these individuals are not themselvesr 

 seed varieties : . With most of thenr the character is so pronouncedv 

 that I an not iuclined to believe so.Of several of these plants I 

 lncluded also seeds for you.Could not the Echinocacti Deppei and 

 acif er in my di ssertatiorr tolerate akower degree of coldness T It 

 is stränge, that these plants are so difficult to bring to f Tower 

 with us.May-be this has its reason as with Echps . Fentlandii , that 

 we keep these plants too warm in Winter. Since I keep this spoiled 

 Echi^ops quite cool and give it a strong, nouri shing soil.it is 

 covered with f lowers , whereas for 10 years with other treatment, I 

 could not fret it to bloony
