Rust on Stinging Nettle Photo by Rodrick Lal — National Geographic Your Shot: When I came across this strange growth on the stem of a bush of stinging Nettle in the mountains of Uttarakhand - India, I felt I should take a few snaps. Growth looks so odd and out of the place. Later I came to know that it is called 'Rust' and it can be found growing on stinging nettle. So much so for parasitic relationships!
