On the other side are the smooth, naked or nearly naked berries 

 of the genus ffhinocactus really not rare, thus e.g# of the Theloldeis 

 with bicolor » Ech . horripllus etc* quite specialis though wlth the 

 nearly related to Theloldeis Bch . Honvillii , Ech , Williamsii », evenr £ch , 

 denudatus , Of the Cephalodeis shows this Bch . Lop^othele » - The C.. 

 Williansonii 1 has a flower and pale red, entlrely naked fruit", which is 

 exactly like that of the true Hanillarla ( jSinami Ilaria) Further, the 

 division Haterocarpus S. has also a totally naked , soft , red fruit, and. 

 this moved the prince, to separate it from Ii Echinocactus ,, for which',. 

 accordinfi: to my opinion,was much less reasorr present, than for the Se- 

 paration of the Coryphantjae f^om the genus Ifanil! nria , or the separa - 

 tion of Eohlnocereus fron Cereus. 



You ask, how Helocactus differs fron the true He^illarlae ? 

 You consider the Points of difference as a. doubtful matter ! I may froirr 

 this conclude, that, if you could find a eorresponden.ee in fruits and 

 seeds.you would be inclined to put the Heloeaetus with the Hamillariae » 

 This I would. consider indeed 9fic&> a great ralsfortune, though I am convirr- 

 ced a priori that you would probably find little difference in fruits 

 and seeds.If you want to ask thus, I believe, I could in botany posit 

 many sirailar questions with related genera. - I send you a^ entire tuft 

 of Heloc » amoenus , within which you will find fruits, and I wish, that 

 the space would have pernitted me to find you an entire specinen, 



Fron your kind letter I get the general Impression, that many 

 cacti are not known to you and not available, which every collector here 

 knows and posesses. I, the^efore, have made the attenpt, to ship to you 

 a whole quantity of partly living and partly-dead cacti of various ge- 

 nera, and. if the high porto were not an impedlment , I would be ftlad- 

 ly Willing, to send you later everything we can provide, and whatever 

 you may desire to have shipped. Of course, I ch ose this time only snall 

 speeimens in order not to enlarge the volune, as I did not want to ask
