ering plants; one hundred and two of Gramineae, or true grasses; ninety-seven of Cyperaceae, or sedge grasses; and forty-nine of Leguminoseae, or plants of the pea family. The whole number of species - one thousand and fifty-two - is almost exactly half the number found to be natives 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 ther everse is true, and that the species are more concentrated into the larger orders. The large orders, Compositae, Graminae, Leguminoseae, 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.
