There's a lot more than just stomata!

Check out this scanning electron micrograph of the surface of a sunflower leaf! Be sure to read the box in the lower left corner!!

I didn't realize that trichomes were so small. I have seen stinging nettles before and had been warned to keep away from them, but I thought that I remembered seeing small hairs that I assumed were the "thorns". Oh well...
I find the statistics about increased water runoff very worrying. I feel that this could lead to a viscous cycle where more flooding would kill plants and result in even more runoff. that could lead to even more flooding and a runoff increase of much more than 24%.
Also, is there a way we can post links? This is pretty interesting; it's an article on genetics: http://www.abcnews.go.com/Health/story?id=6998135&page=1
