Chrysanthemum ×superbum of Michigan Flora.

This is a well-known horticultural plant, presumed to be a hybrid between two European species; quite variable, with numerous cultivars. First collected outside of cultivation in Emmet Co., in 1948.

The heads are similar to those of the weedy ox-eye daisy, but they run larger and the leaves are merely toothed rather than lobed and well developed toward the middle of the stem (rather than toward the base).
