thence to include about two-thirds of Lake Ladoga, and continued 

 just north of St. Petersburg and Kronstadt to the Gulf of Finland. 



Perhaps nowhere else in Europe is there such an extensive and 

 intricate series of lakes and rivers as in South -central Finland. Of 

 the botanical districts, that of ''Aland" (the group of islands so 

 named) is perhaps the most interesting, no less than fifty-six 

 species being found in that province only. 



The flora is richer than might be expected, looking at the great 

 difference in the vegetation of the west side of Norway, and the 

 east side of Sweden bordering the Gulf of Bothnia. The north- 

 western districts have many plants that are exceedingly rare, or 

 scarcely found elsewhere in Europe. 



A new species of Potamogeton (P. Wolfgangii Kuhlman) is 

 admitted, which in the 1st ed. was called P. nigricans Fr. This 

 has been gathered and distributed as "P. salicifolius Wolf.," which 

 it is not. P. nigrescens Fr. had three distinct values m its 

 describer's eyes ; but the original specimens from Lapponia Pithensi 

 1824! were a form of rufescens, as Laestadius so named them. 

 Abiiis glutinosa L. occurs north to lat. 65° 28', "fertile " ; in Norway 

 it occurs north to 64° 19' : Querciis pedimculata to 61° 5' (Norway 

 to 62° 55'). Ubnus montana With, to 62° 36' (Norway to 67° 17') : 

 Tilia ulmifoUa Scop, to 63° 30' (T. parvi/olia in Norway to 63° 40'). 

 A new Taraxacum is described — '' T. nivale Lange in litt.'' Many 

 interesting remarks on what may be only local forms will be found, 

 but this notice of a local Catalogue is already too long.
