cross section of dune grass leaf
The photograph at the top of this post shows a cross section of the leaf of marram grass Ammophila arenaria. Marram grass survives in the arid environment of a sand dune by rolling up its leaves during long periods of drought, so that all the leaves’stomata are inside the rolled leaf, minimising water loss. This cross section of a partially rolled leaf has been stained with fluorescent dyes to light up different cell types within the leaf....The scattered structures that look like ‘smiley faces’ with a pair of large ‘eyes’ with a blue open ‘mouth’ – these are the leaf veins that conduct water and sugars along the leaf – they’re the plant’s internal plumbing system.

Thanks for the reminder to slow down and observe what's around me. I think Yogi Berra supposedly said "You can see a lot by just looking."

I was just thinking about what a beautiful day it is. Saw a five point buck at work this morning. It's warm out.
Everything is pretty darn good!
