Can you see the lined spores on the back frond? This is fern spores. Spores appear as
little bumps. I'll pick up a mature fern frond with tweezers. A large quantity of spore
are contained in every tiny piece. So you sprinkle the spores over the soil to keep
humid. And be patient several months to sprout. I'll let them naturally. But I want
to buy a microscope and examine a fern spore through microscope.
