is an annual herb native to North America, growing wild in
various regions, and reportedly causing pollenosis from summer to
autumn. Stems generally have vellus hairs and reach heights of
0.3-1m. Leaves are tender, opposite on the lower parts, alternate on
the upper parts, and deeply bipinnately cut. Male flower heads,
3-4mm in diameter, set themselves in slender racemes facing
downward, and female flower heads gather together at the axils at
the bases of the inflorescences in a nearly unnoticeable way. Bloom
time: July-October. |
