** Etuberculatae: :The Tuberculatae would later part into f appla- 

 nafeas (lanigerae) and (felabrae) and in -J--J4 cristates; as well as 

 th e Etuberculatae into f frutescentes and ff suf frutescentes» . I T 

 only sketch my idea very superf icially jrThere should not anything- 

 essentiall.be changed in your Organization according to the nature 

 of the seeds«. The Ellipticae (better perhaps as contrast) the Appla- 

 natae remain unchangedi; Only the Cylindraceae would divide into 2 

 ^: clavatae and cylandrices» . 



What concerns the cacti of Potts, Mr. Scheer has taken over 

 to describe them and to publish in the periodicali Bomplandia (by 

 Seemann)' • until now nothing has appeared. . Poselger has, since his 

 description of cacti in f 53 in the Garten Zeitung, published 4 new 

 Speeles.. You know his descriptioans from tear 1 53 and his Cereus 

 tuberosus is quite a good species-, which^ is easily to be distin - 

 s-uished through its quill-thick seed and the tuberous root^rl en- 

 close a copy of the 4 new cacti described (in the No. 3 of the 

 annual set of this year) . - 



The furrow on the warts of the Mamlllariae indicates quite 

 certainly the connection betweeirthe flower-bud and the spine bündle;: 

 this connection, though, is also present, where no furrow exists to 

 be seen : • stränge is the appearance of this furrow only then f when 

 they come into flower«. 



I have answered as well as I can to your letter;: A<€cept f , 

 Your Wellborn yet the assurance of my complete esteemr
