The character of this group is shown by the fact that some 30 out 

 of the 45 are hill or mountain species, though very few of these are 

 confined to high elevations. Ponr are water plants; five frequent 

 marshes, and four peat bogs. One is a maritime species. Only six 

 affect dry or cultivated soils. The group is characterized by an absence 

 of either calcicole or calcifuge plants. Analyzed according to the 

 British types, the Highland and Scottish species largely predominate ; 

 out of 38 classed by "Watson, nine are of Highland type, ten of Scottish; 

 six more have Scottish tendencies. Only five are English. Only one, 

 Adoxa, is of British type. 



For the construction of our statistical map, we have a maximum 

 of 37 species (or 82 per cent, of the group) in Antrim, a minimum of in 

 various southern divisions. The northern grouping of the species comes 

 out clearly.
