424 BOTANICAL GEOGRAPHY. 



Phyllodoce, Kalmia, and Cladothamnus confined to Sitcha ; Pyroleae, 7 sp., 

 corresponding to the German species ; Monotropeae, 1 sp. 



The 5th and 6th parts of Trautvetter's illustrated work 

 1 Plantarum imagines Moram Rossicam illustrantes/ Mo- 

 nachii, 1845, 4to, (see the preceding Annual Report) 

 have appeared, containing pi. XXI XXX. 



The Academy of St. Petersburg has commenced the 

 publication of Contributions to the Botany of the 

 Empire of Russia' (Part 1, Petersburg, 1844, 30 pages 

 8vo. ; part 2, 67 pages and 6 plates ; part 3, 56 pages ; 

 part 4, 93 pages; ib. 1845). 



The first part contains a local flora of the province of Tambow (incomplete, 

 containing 312 sp.), forming Ruprecht's fourth contribution to the flora of 

 St. Petersburg. The same author has published an account of the Eerns 

 and Charge of the empire of Russia in the third part ; it also describes some 

 new Terns from Siberia, Mongolia, and American Russia, as also of the 

 Charse from the Soongari. 



The second part, in which Ruprecht has described his botanical travels in 

 the extreme north of European Russia, is of more general interest. In the 

 unfavorable summer of the year 1841, he collected in the eastern part of the 

 province of Archangel, especially Mezeu, the peninsula of Kauin, and the 

 island of Kalujew. The natural character of the country differs from that 

 of Scandinavian Lapland in the circumstance that the forest-limit recedes 

 almost to the vicinity of the arctic circle ; hence extensive, low, treeless 

 plains are spread along the arctic ocean. Thus the pine forests are en- 

 tirely absent at Kanin (excepting a wood composed of Abies, situated below 

 67} N. lat., and which is now dying) ; they cease at the Indega river, about 

 fifteen English miles from the sea, and scarcely extend over the arctic circle 

 beyond Petschora. The cultivation of barley and potatoes also is only 

 carried on as far as the city of Mezen. The forests are succeeded north- 

 wards, first by a zone of low birches and willow-shrubs, the dwarf birch 

 with the arctic Ericacea? follow next, and lastly, with the latter the continuous 

 turf of the alpine regions terminates. A few Ranunculaceae, Saxifrages, 

 and Grasses, which only partially cover the soil, are all that are subsequently 

 met with. In these travels 342 Phanerogamic plants altogether were col- 

 lected. They also differ from those of the flora of Scandinavian Lapland, 

 in containing a large proportion of species which are riot Scandinavian. 

 Eleven new species, which are illustrated by figures, belong to the genera 

 Ranunculus, Viola, Parnassia, Salix, and Poa (7 sp., 1 sp. of each of the 

 others).
