Velco-like seeds, too.
If the seeds attach themselves to your clothes you can run the clothes through both the washer and the dryer and the seeds will still be stuck on your clothes. Very well-designed seeds!
By the way, there is currently no shortage of these plants in my area. Each time the earth is disturbed, long-dormant seeds emerge and thrive. The newest location is along our newly completed highway - The Truman Parkway - is lined with Desmodium plants of one variety or another. A beautiful sight if you happen to be a Skipper, or a deer, or an aphid, or a stinkworm....
