44,4 X. GENERAL REMARKS. 



Scotland from England, and distinguishes the latter 

 into western and eastern, the figures will reckon up 

 thus : — 



W. England, 30. E. England, 22. Scotland, 25' 

 These last three figures would be reduced to 26, 21, 18, 

 by omitting five segregate or spurious species of Ruhus, 

 and seven such species of Hieracium. Turning to the 

 group of 54 sj)ecies apparently restricted to two sub- 

 provinces, the figures come out thus : — 



South Britain, 34. Mid and North Britain, 17. 

 To which three other species must be added, as common 

 to the two divisions, namely, Hieracium lasiophyllum and 

 JRuhus Bloxamii, with the Eriophorum gracile, not quite 

 certain in the North of England. Again, by the ternary 

 division, the same 54 plants are found distributed 

 thus : — 



W. England, 11. E. England, 22. Scotland, 12. 

 With nine others common to two of the three divisions. 

 So far, it appears that among the 131 very local plants 

 those of South Britain are considerably in excess over 

 those of North Britain. According" to the first com- 

 parison the very local plants of England are more nume- 

 rous on the western side ; but by the second comparison, 

 that of plants ascertained in two sub provinces, the 

 western excess of the first comparison is found to be 

 compensated by an eastern excess in the second ; the 

 united numbers being 41 and 44. 



Turning next to the ' areas of species,' those indicated 

 by the single nos. set after their names, as being appa- 

 rently each restricted to a single primary province, are 

 apportioned among the provinces in the following num- 

 bers : —
