(ft***) coerulescentes (as earlier ; only raoved frorr ^ Angulati to the

 Classification, about which I will have to say sone nore.. 



Your Wellborn will see, that though the Echinocerei have been 

 divided into two sections, these stand side by side. The group of 

 Lophogoni is quite natural ani easy to recognize; the species, how- 

 ever are not easily separated where they belong. Ehrenbergii is the 

 smallest, thinest, and nost prolif erating species and nostly bristle- 

 like spines. C. cinerascus DC is a species well known in our Wardens. 

 1t is probably a southern form- fron. Mexico, thick, nore fleshy, with 

 streng spines ( you musfe" have seen the plant in. Berlin). These spines 

 are whitish "cineraseentes*. In both varieties assigned to this spe- 

 cies, the spines are colored and stronger, which pass into Roeneri , 

 and, would, possibly, be better associated with it. G. acif er of 

 Otto may also belong there. - To consider all these plants as diver- 

 gent forms of one and the sane species, is raostly not proper.! and 

 to separate then correctly (as we do not know the f lowers) ^ is a daring 

 enterprise.. - The sarae goes for your C. coe sipj tosus (there is further 

 the question,if the name .peotinatus 11 fron year 1839' 1 is the older, 

 to be decided). The 6 forms, which you sent to me, belong, however, 

 together beyond. doubt; there are though also other forms with stiff ,. 

 red spines, which I preserve as sceletons, and tb-^oug^ which it may 

 become possible, to determine a second species; be cause your 6 forms 

 with. 2, which I know, would add to 8 forms, and that is almost too 

 much for one and the sane species. - G. Scheerii , which I put into this 

 group, is very different from coespltatum - and can in no way be ml staken*.
