Two to five feet tall. Leaves
long-stalked, coarsely toothed and all in pairs opposite each
other. Flower heads about 2 in wide. Disk flowers in
center orange to yellow. Ray flowers ("petals") yellow,
strongly wrinkled. The ray flowers are fertile; with a hand lens, a tiny forked pistil is visible at the base, as in the picture at right.
Plant of open woods, occasional along Riverway
bikepath in Wildwood. Blooms in late summer.
There are a number of yellow sunflower-like
plants in the Park. The leaf shape, the leaf teeth, and
the fact that all leaves are opposite is a good indication you
have found this plant. A clincher is to examine the ray
flowers with a hand lens and look for the pistil at the base; true
sunflowers do not have fertile rays.
