Here are the strange and excessively efficient pistillate flowers of shagbark hickory. No showy large parts here. Just enough to catch some pollen out of the wind and cook up some tasty nuts. The shaggy bark of this tree looks like it has to be good for something. Apparently the ancient doctrine of signatures still functions in some quarters. God made it that way to tell us it was good for our skin? The powdered bark is used in some skin lotions. And, even more mysteriously, in medicine for cat urinary problems. Actually, if you get beneath the skin, you come to great hard wood and sap that makes a passable syrup. Shagbark crosses with pecans. That hybrid, hican, is sometimes cultivated.
