The botanists say that it is due to the flattened leaf stalk, which is set perpendicular to the surface of the leaf, making a combination which renders the foliage so susceptible to the slightest move- ment of air. It is also an adaptation to strong wind. The flat petiole permits the leaves to twist easily and reconfigure, accounting for the resistance of aspen and other poplars to wind damage. C.
