328 GEOGRAPHICAL BOTANY. 



than in the inland districts, but which, in fact, do not 

 correspond to this view. The author is certainly of an 

 opposite opinion, and states that the number of indi- 

 viduals increases towards the west, which I should much 

 doubt ; but it is certain that Hymenopliyllum Wilsoni can 

 alone be considered as an evidence of the marine climate, 

 whilst the inland country contains five more of the thirty- 

 three ferns which are here enumerated than the west, viz. 

 Polypodium calcareum; Aspidium Thelypteris, cristatmn, 

 montanum, and crenatum Sommf. On the western coast, 

 Aspidium aculeatum and Asplenium adiantum nigrum, 

 which are not found in the east, extend as far as 

 Trondjem, but they must be considered as forms belong- 

 ing to the south, not to the coast. 



I can only refer here to my paper upon Hardanger (see 

 Wiegm. Arch., p. 1-28) ; still I cannot omit this oppor- 

 tunity of replying to the editor of the ' Botaniska Notiser' 

 (see that journal, 1844, appendix, p. 64), that the beech 

 is certainly cultivated beyond Christiansund. Blom, whose 

 authority is Blytt, makes this statement. (Das Konigreich 

 Norwegen. Leipz., 1843, p. 48.) I did not say that it 

 grew wild there, as Lindblom has erroneously stated in 

 his translation, and the only object I then had in view, 

 was to show how far north the climate was suitable to 

 the growth of that tree. I found single specimens of 

 Helianthemum alpestre on rocks near the herdsmen's hut 

 Oppedals-Stolen, and have given specimens of PJtippsia 

 from the same region to several botanists. However, I 

 place little value upon these new localities, of which I 

 had several, and I should consider it as the best recom- 

 pense for the labour of my memoir, if Lindblom and 

 other able Scandinavian naturalists, instead of filling 

 their Journal with unsatisfactory lists of the results of 

 their excursions, and critical minutiae regarding the dis- 

 tinction of species and their nomenclature, were also 

 induced by it to direct their scientific attention more and 

 more to the conditions of the distribution of plants in the 

 North of Europe.
