Your Highborn 



Tour kind letter of October 21 has beerr delivered to me 

 through your brother, and I admire tbe speed by whichr the long- 

 distance between St. Louis and here was negociated. ~ I an very 

 much obliged to your Highborn f or the kind renenbrajpce y as you re- 

 call. Since that time, much has been changed in the Berlin Garden! 

 Otto left, and the culture of cacti has practically been abalc^oned., 

 As to your supposition, to consider perhaps known species as new 

 on.es, this raay be not without good reason. Cacti 5 seem to be , as it 

 seems, assigned to rather restricted habitats in their homeland, 

 and rarely does rone find the same species in distant lojfcalities#. 

 Mexico, Columbia, Brasil, and the West coast fron Valparaiso to Me- 

 xico have been explored; not explai nable, however, . that every nextf 

 collector, who visi^ts these territories, finds still unknownr plants.. 

 The northern part of Mexico, Texas and California ( though sorae cacti 

 have cone fron there to Europe) must be considered as unkrown. But,, 

 even the area in which you live, must be considered as not fully ex- 

 plored; we know fron there only on.ni ss our i e n s i s DC. (cact 



Nutt. ) and the Mäm. vivipara • (c act . viviparus Nutt.) . The first 

 grows ha ppily with us; the latter is sickly but endurlng^, and it 

 would therefore be very desirable, to recMgwe healthy and strong 

 speeimens fron its homeland. Huttal also risms the Op . mesa.oa^tha „ 

 coespitosa and hunifusa as native species of Kentucky,, and these 

 are entirely unknown to us, and have never been introduced into our 

 gardens. . Further, prin.ee Max von Wied spoke to ne about an Op., 

 which he had seen on the Upper Missouri and the Rocky Mountains, 

 Of these species I would be nost eager, as they may not grow with 

 us und er open sky. .
