IN OTHER COUNTRIES. 91 



V. REMARKS ON THE DISTRIBUTION OF BRITISH 

 PLANTS OVER OTHER COUNTRIES. 



To enter into full details on the geographical distri- 

 bution of 1400 species would speedily expand the present 

 sketch into a voluminous work, far beyond the dimensions 

 within which it is wished to confine it for the present. 

 At the same time, I feel reluctant entirely to omit the 

 distribution of our indigenous species over other coun- 

 tries, — the consideration of such, in connection with 

 their local distribution in our own island, tending ma- 

 terially to a correct appreciation of the latter, and to 

 elucidate the conditions on which they would appear to 

 be dependent. On this account, it is proposed to take a 

 brief and connected glance at the general range and dis- 

 tribution of our indigenous trees and shrubs, chiefly in 

 connection with the natural geographical divisions of the 

 earth, and the more particular distribution within those 

 countries, the floras of which have been geographically 

 considered, namely, Lapland, Sweden, Sicily, France, and 

 the Carpathians. The reader must be referred elsewhere 

 for more full and precise information on the climate of 

 the several countries, than is compatible with the intended 

 limits of the present work. With regard to the tem- 

 perature, the well-known table of Humboldt (Edin. Phil. 

 Jour. vol. iii. iv. v. ; Murray's Encyclopaedia of Geo- 

 graphy ; and Ure's Diet, of Chemistry, — Climate) should 

 be attentively considered ; and additional information 

 (where that table is most defective) will be found in the 

 Edinburgh New Philosophical Journal, from the pen of 

 Dr. Richardson. 



Spitzbergen contains only one of our shrubs, and that 

 of smallest dimensions, — Salix herbacea. The mean tern-
