species—one thousand and fifty-two—is almost exactly half the 
number found to be native of the Northern United States; and the 
same remark holds good when we compare the numbers of each of the great 
classes of plants. It will be seen, too, that there are in Illinois, 
more true grasses than Cyperaceae; while in the whole Northern 
United States the reverse is true, and that the species are more 
concentrated into the larger orders. The large orders, Compositae, 
Grammae, Leguminosaae, Scrophularinaceae, Ranunculaceae, Labiateae 
and Umbilliferae contain, respectively, more than half the species 
of the Northern United States while only Cyperaceae and Rosaceae, 
among the larger orders, contain less. 
Of one hundred and thirty-two orders, found native in the 
Northern United States, one hundred and eleven are represented 
in Illinois.
