on which you will observe distinetly, that mostly toward the tip f , 

 the long central spines have been lost alraost without trace*. This 

 is actually the europaean post-growth of the plant.. On this va - 

 riety I could not observe any sign of f Towers or once existing- 

 fruit s in its homeland.. As long as I speak about this species*I 

 can only reneat , that I can not wonder enougfr, that you could pull 

 it into the genus Echinocereus », If you consider this correct, than 

 you will have in consequence put Echinopsis tuberculatae also there» 

 Of these Echinopsis pjtntlandii , with its numerous varieties , which 

 all have an about 2 11 long floral tube, covered with naked, smoothr 

 scales, provides the natural transition to the E c h i no p s a e » Then, 

 you. would get almost to the same point as Pfeiffer, who drew the 

 entire genus Echinopsis to Cereus .and, forned fron them the divi - 

 sion Cerei p-lobosi ». 



As to\:h.e combining, proposed by me,of the wrinkle-bearing 

 (could be "furrow-bearing" E.D.) Mamillariae with the genus 

 Echinocactus : - you. may know already, that prince Salnr i s also not 

 of ray opiniorr, with. the only difference, that his reasons ap-ainst 

 it are even rauch less cop-ent than yours«: I do not want to fin-ht 

 with you today aboutjthis point theoretically, I hope however, that 

 in the not too distant future I will be able to furnish you seeds 

 for sone of the involved species (speoially of Ech . Saltillensi s 

 Poselg ) ,for which you will have to agree, that they are sinilar to 

 the Echinocacti , Now t I want to only direct your attention to this;: 

 The fruits of these Mangtilariae are all more or less greerr, relatlve- 

 ly very large,, however raostly naked, but not always sojthus, e.g. 

 there are on the fruits of all varieties of Ham ^ pycnaycantha sone 

 hardly visible scales, which end in beard-like fine hairlets..
