II. FLOEAL AREAS. 379 



small space here, a botanist will find no difficulty in 

 believing that it has required more than a small amount 

 of time and patience in the making. The floras for all 

 the areas are compilations brought as closely as could be 

 to the same uniform standard, as regards nativity and 

 specific distinctions ; being adapted to the ' summary of 

 distribution,' in former pages of this volume. The floras 

 for the divisions and provinces are considered to be 

 nearly complete ; those for several of the sub-provinces 

 being much less complete. It was, indeed, partly in 

 order to call attention to those portions of Britain, for 

 which the floras seem to be less fully known, that the list 

 has been extended so as to include every', province and 

 sub-province ; the selection of half-a-dozen being other- 

 wise sufficient for the one object now more immediately 

 under view ; namely, the numerical relations of the flora 

 to the size of its area.
