A trap for parasites

I had never seen these "warts" on this plant, so I got curious. After some investigation, it turns out that the plant produces each "wart" to trap - and suffocate- a parasite, so that they can't harm the plant or reproduce. So clever!

Isn't nature amazing? They make an interesting texture for photos too!
