Moreover, by the position assigned to the minor groups in the for- 

 mula at p. 710, we get rid of the difficulties which would be other- 

 wise encountered in locating these groups so that their relative 

 affinities might be clearly expressed. The rhizogens, for example, 

 affording, as they do, a natural transition from the exogens to the 

 thallogens, cannot be more naturally placed than they are in the for- 

 mula at p; 710 ; which position dissipates Mr. Griffith's objection 

 that Dr. Lindley has placed them " after or in Monocotyledones." 



In conclusion, I cannot help expressing my opinion that the Sys- 

 tem developed by Mr. Newman offers fewer objections and seems 

 more in accordance with all the requirements of a natural arrange- 

 ment than any other with which I am acquainted. This is a most 

 legitimate subject for discussion in the pages of the 'Phytologist;' 

 for although I expect to see Mr. Newman's views entirely con- 

 firmed by every fresh discovery, yet I must confess that I am not so 

 wedded to my own opinions on certain points as to suppose them 

 proof against free and fair discussion. If no one better qualified 

 should think it worth while to work out the minor details of classi- 

 fication in accordance with the System above propounded, I may, if 

 ever I have leisure, attempt to do so. For the present, so alarmed do 

 1 feel at my own temerity in having broached my ideas on this intri- 

 cate matter, that in taking leave of the subject, I may say with Mac- 

 beth, " Look on't again, I dare not."

Occurrence of Carex digitata near Cheltenham. 

 By Charles Prentice, Esq. 



I W'iSH to state that Carex digitata grows sparingly on the lime- 

 stone ledges of Cleeve Hill, about four miles from Cheltenham, al- 

 though it has been most unaccountably overlooked by Mr. Buckman 

 in his local Flora of Cheltenham, which is, however, inaccurate in 

 several places. I shall be very happy to communicate specimens as 

 vouchers of my accurac}'.
