LEDEBOUR, Flora Rossica. 
So vast a work as a Flora of all the Russias could scarcely 
be confided to abler hands than those of the author of the 
* Flora Altaica" and of the splendid “ Illustrations” of the 
same Flora. The first volume, accompanied by a Geo- 
graphical Map, is already out, extending to the end of 
Leguminose (following the arrangement of De Candolle). It 
is entirely in Latin, with generic and specific characters, and a 
very full list of synonyms and habitats. Of the vastness of 
this undertaking some idea may be formed by an enume- 
ration of the regions which it will include, as defined by 
Dr. Ledebour. : 
A. Cis-Ural portion of the Empire. 
1. Arctic RussiA, or European Russia beyond the Arctic 
Circle. 
2. NonTHERN RusstaA; south from the same circle, to 
where the Oak appears. 
3. Mippte Russta; from the southern limits of the 
latter region to where the Vines are cultivated. 
4. Sournern Russia; the whole country from thence 
to the southern limits of the Empire; but this again is 
divided into 
5. Tauria; the Taurian peninsula, and 
6. Caucasus, or the great district occupied by the Cau- 
casians, of which the northern limits extend to 45? N.; on 
the west, to the mouths of the Kuban, and on the east to where 
the Kuma flows into the Caspian Sea.
