Native. Sylvestral. Whether or not this be deemed a 

 species distinct from E. latifoHa, the recorded localities of 

 the two are so thoroughly mingled in books, that it is im- 

 possible at i^resent to assign them respectively to the 

 sj)ecies or variety really found in places on record for E. 

 latifolia ; a few of the stations truly belonging to neither, 

 but to E. ovalis only. Thus, for the present, the distri- 

 bution of E. latifolia, as given in the second volume, page 

 417, must be understood as founded upon the localities of 

 that species, more or less mingled with those of E. media 

 (with purpurata) and E. ovalis. And the distribution of 

 the two latter, as here set forth, will be less full and com- 

 j)lete than it should be ; being founded upon a limited 

 number of localities, ijerhajis much fewer than the reality.
