What kind of plant produces small triangular hitchhiker seeds?

My knitted hooded jacket was covered with these tiny seeds after I took a walk.

The seeds are small, flat, long triangles, with two barbs at the top of the broader end.

What is the plant that produces these called, and what does it look like?

Sticktights, or beggar ticks (Bidens spp.) come in three varieties, all of which have the same type of seed. It’s small and brown, sort of triangular in shape, with singular prongs sticking out from the corners on either end of the short side of the triangle. The plant itself is rather non-descript, but at least it is native. And while the seeds stick to your socks and pants (or poncho), like a pitchfork stuck in hay, they are painless to remove and do little damage to your clothes or flesh.

Dandylions are small plants that produce many seeds fast, and we all love to blow them in the wind, they are pretty weeds, for sure.

To remove them, place your hand in the leg of unwanted pantyhose. With the palm side of your pantyhose hand, run your hand over the garment. The hitchhikers should remove fairly easy; I hope this helps.
