PLANTS WITH HAIR.
Some plants have hairs on their leaves, making them feel rough to the touch, as I've heard. This can be seen very plainly by looking at a common mallow-leaf through a microscope. And there is the mullein, too, with very stiff hairs.
Now, what are these hairs for? I have been wanting to know this for some time, and should be glad if some of you clever chicks would look into the matter, and tell me what you find out.
