Every sycamore presents a unique visual history of it's survival battles: Twisted and gnarled branches; dead limbs; hollowed trunks and numerous nest hole cavities. The smooth white bark gives it a very stately look.
The stipules might hinder movement of herbivorous insects that are crawling up and down the stems. Caterpillars for instance would have to climb over the obstruction temporarily disrupting their usual camouflage tactics and thus vulnerable to predation.
