My most honored Friend 



Of course, I did not receive your letter in Colorado, which 

 I had left long ago; but it followed me here. I am delighted , that the 

 Ecblrocactus Simsoni seems to hegin ^r^othjit grows very poorly in 

 cultivation; may it demand nore moi sture. Where it grows, it is co - 

 vered the entlre winter with snow, but there is very little rain in 

 Summer, but frequent, With me, it has a"Lways perished. 



Today you receive seeds f or a new, in te^e stirer Zchi v, oo ^,ctU8 



which I name xerar themoi des ; The calyx leaves are paper-like, stif f , 



light 



shinyylike a Xerarthemum or Kelychrysum , but ' , vellowish. I have 

 only one fruit and one spitte-bundle. It is closely related to my E. 

 pol vcephalus and most likely just as difficult to cultivafce; it 

 comes from the boundary of Utah a^d Arizona. 



Purther I enclose seeds of Cereus t r i gl o o h i d i a t u s , wh ich I 

 coltected myself in New Mexico. I prefer the name, which was given 

 later but is better, C. gonacanthus , as the number of spines with 

 edges is mostly nore than three. It is a fine, strong plantwho'se 

 bushes I found below conifers at an altitude of 7,000 - 8,000 feet. 



The^ you. receive 2 Pia t Dipunt i a e , t h e one fron Arizona may be 

 my C . an.cru.stata . The other I assume to be 0, Camptnchlca from South - 

 Colorado, which looks to me almost like a robust form of 0, Ha fine s - 



flJÜl. 



I have nothing new of Agavae. Would you be interested in a 

 seedling of A. Si salcw **? This long-leaves, spineless form is very stri- 

 king. It is about time, that I Start a new treatment of our cacti; 

 I got so much material and so much to improve of old items t that it 

 would. be a worthwhile labor,and. , besid.es, there is nobody, who cares 

 «mQ&ü about them and is occupied scientif ically with them; and how 

 long will it be, when my activity too will come to an end !
