Taking these up in order, let us first note the character of 
the northern element :

In this table, as in the next three of its series, there is an 
exact parallelism with the four generic tables of similar con- 
struction. While the Archichlamydeae from their number 
form the larger percentages of each range-element, the taxo- 
nomic groups themselves analyse as before by range-elements. 
The other three tables may-now be added.
