GEOGRAPHICAL BOTANY. 323 



I. EUROPE. 



A work, containing copper-plate engravings of the 

 plants of Russia, has been begun by Trautvetter (Planta- 

 rum Imagines et Descriptions . Monachii, 1844, 4 fasc., 

 1-4 ; at present 20 plates). Also a continuation of the 

 old ' Bieberstein Centuries' (M. de Bieberstein Centuria 

 Plantarum Rossise Meridionalis Iconibus illustrata ; Pt. 

 ii, Dec. 1-3. Petropoli, 1844,) has been commenced 

 in St. Petersburg. Engelmann has published a paper 

 upon the Genera of Plants found in the Russian provinces 

 of the Baltic (Genera Plantarum, or the Genera of Plants 

 growing wild in Esthonia, Livonia, and Courland ; 

 Mitau, 1844-8). 



A. E. C. v. Fischer has written upon the botanical re- 

 lations of Southern and Central Lithuania, especially in 

 the circle of Sluzk (Mittheilungen d. Natur. GeseUschaft 

 zu Bern, for the years 1843-4; Bern, 8). In the im- 

 mediate neighbourhood of Sluzk, in the district of the 

 source of the Niemen and several tributary streams of the 

 Dnieper, the author only found about 600 Phanerogamia, 

 a catalogue of which he gives, with remarks upon their 

 statistics. In these districts, heathy plains, overgrown 

 with Calluna (together with Juniperus and Genista tine- 

 toria) are still common. Dwarf underwood, consisting of 

 the oak (Quercus pedunculata) covers large spaces, and 

 stamps the physiognomy of Lithuania towards the western 

 districts of the Baltic plain. In moist low grounds Salix 

 angustifolia and livida predominate. The large forests 

 consist of pines or fir trees ; the truly foliaceous trees, 

 which are less common, are mostly birch, and in Polesia, 

 the oak, which grows mixed with the birch, poplar, moun- 

 tain-ash, &c. The following may be mentioned as geo- 

 graphically characteristic species: Thalictrum aquilegifolium 

 L., simplex L., and anyustifolium Jacq., Anemone patens~L.,
