odor. It is an annual that reproduces by seeds, sometimes in cultivated fields, sometimes in
run-down pastures. This weed is bushy and hairy atop a fibrous root. Leaves alternate in
general and are deeply bipinnated, variable and also hairy. Flowers are very small in ter-
minal clusters. Some few heads at the base have pistillate flowers. The upper flowers are
