originating in North America, is an annual that broadly naturalizes
in various districts, with many stems tingeing brown-purple, growing
to 0.5-2m in height. Leaves, with long peduncles, are of alternate
phyllotaxis, in an ovate or broad ovate shape, shallowly cleft
halfway in 3-5, with uneven serrations on margins and sandy lower
and upper surfaces. Dioecious: Male flower heads are set in the
inflorescences that have emerged from axils, and female flower heads
are at the bases of the male inflorescences. Bloom time:
August-November. |
