once said, "Queen Anne's Lace is to the carrot as Asian jungle fowl is
to the chicken." Indeed, Daucus carota is the
wild form of the cultivated carrot. It is also a serious weed in Missouri.
As the compound umbel matures it folds in on itself trapping all the spined
fruits until some animal brushes the plant and is covered with the seeds.
