Many of these plants are identified with those of Koch by the in- 

 spection of authentic specimens, but we are sorry not to see more 

 observations upon the rank as species or varieties which the several 

 plants are entitled to claim. The valuable synoptical table given 

 with the former fasciculus is not continued in that before us ; for this 

 however there is one consolation, namely, that the author states his 

 intention of preparing a third fasciculus in which it will be con- 

 tained. 



We take the present opportunity of publishing some valuable 

 notes upon Mr. Leefe's Fasc. I. with which we have been favoured 

 by M. W. Sender, the distinguished botanist of Hamburg.
