The wetter middle portions of the transect are occupied by 
species of limited range only and in these the northern distri¬ 
bution is strong. In marked contrast is the drier border por¬ 
tion with large numbers of species and a marked mixing of 
range elements. 
The geographical distribution of the fifteen species most 
abundant on the whole transect are tabulated below.

While Car ex stricta is to be considered as a member of the 
northern element its distinctive range is E* S E and as such it 
belongs to a region that has few representatives in the marsh.
