Bidens pilosa - Wikipedia Bidens pilosa is a species of flowering plant in the aster family.

It is a tall branched weed with thin yellow flowers that develop into a cluster of barbed fruits. Dispersal of Seeds by Wind - The Seed Site Many members of the Daisy family provide their seeds with a flat disk of fine hairs to produce a parachute to keep the seed aloft. Bulrushes produce many millions of dust-like seeds, each of which has its own tuft of fluff to give it a bigger area to be caught by the wind. Examples of seeds spread by this method are:
Bidens pilosa. Its little black seeds hook onto clothes or horses and thereby the bur spreads itself around. It is susceptible to hand weeding if small enough, even then must be bagged, and thick mulches may prevent it from growing. Each seed has two to four barbed spines. A weed of gardens, woodlands, and waste areas,...
