that this could impossibly be assiprned totribus Melocacteae; Hooker 



says 11 The blossom differs in no particular fronr that' of 



Cereust . das fernen is thus exsertum, . and that is suf f icient to put 

 the plant' to the trlbus Echinocacteae , und er Cereastreae, f ron the first 

 it distances itself by the length of the tubus perigoniil, s and fronr 

 both~ through its abnormal habitus; it Stands, so to say, , betweerr both 

 tribus, and. it could' forn a new tribus (if at this tine it would not 

 stand all alone, and if a tribus character could be derivated: fron a 

 Single plant) !, But I preferred, as I say in a rote,, to put it to the 

 Cereastreae, . and . as the first genusr? in that it : joirrs the last genus 

 ,.Bchin.ocactus' throu^h this positi on-, . which" d eviates through its tuber- 

 cula distincta,. spiraliter disposita fron the ordinary forn of Echi- 

 nocactus ,. offerlng a real transition character,. For two diffe^ent Spe- 

 eles I have the copy of the text by Mr. Hooker-, and for both" it says 

 H our plant s were obtained for us fron the neighbourhood of Rio del 

 Monte, Mexico through the favour of John Taylor Esq. 11 



I do not have anything eise to renark about the genera, only 

 still, that the species is derived fron the tribus chafcactei% ? bringing 

 them by themselves into the natural sequance». What concerns sections,, 

 I tried: also to bring these into a natural sequence,, and also in. the 

 nost expedient concerning the transitions fron one genus to another., 

 The Hanillariae ; y a^e ne the- nost trouble, as I do not posess mature 

 speeimens of all species l With the § Centrispinae I an not quite 

 satisf iedf, but did not know yet Eow to do it better.. There are spe - 

 cies therein, which perhaps belong- to § 2 crinatae; or reversedvare 

 in this, but belong into the otheiv It may be necessary to forn a ^ 

 viviparae; because, also in the £ 11. Anlacothelae are sone species 

 ( scolynoides and calcarata ) , which could belong to such a one, but as 

 I basically do want to plan the way, on which one can progreif, all 

 are retained, , sub j ect to future improveraenta» . About the sections
