A plant with hooked seeds or prickly surfaces that stick to clothing or animal fur, aiding in seed dispersal; also called catchweed or sticky plant.
From 'catch' + 'weed,' descriptive of how the plant catches onto things. This is likely a folk name created by people observing the plant's seeds sticking to their clothes.
Seeds that stick to animals aren't accidental—plants evolved this strategy brilliantly. Catchweed demonstrates co-evolution: the plant benefits from transport, animals might benefit by spreading seeds in new territories, and humans end up with annoying burrs in their socks.
