and the utmost extent of our knowledge of the distribution 
of species is limited to a few particular remarks accompany- 
ing the description of specific forms in our lists or floras. 
The time must no doubt come, when a different system will 
prevail ; but in the mean time, an attempt to describe the 
vegetation of a particular natural district, may excite per-
