Java Fern
 

I have several java ferns in several different tanks but this one plant has
rasied brown bumps on the undersides of the leaves. What are these? Here is
a pic

They look like sprouts, I agree... I've seen it on mine, but more
black, so which ever, my java ferns always seem to sprout from the
undersides of the leaves...
