Gingko trees are described as living fossils, as they're nearly unchanged in the past 200 million years. This makes them one of the oldest species of trees on the planet. I think these stomata reflect that ancient churning to time.
Stomata(square objects) on a needle from this same tree. What is the advantage of this pattern? What role do the different shapes and structures play? Could it be applied to breathable membranes?
Scale: 40 stomata would span the head of a pin
