aspen (Populus spp.; WILLOW FAMILY [Salicaceae]) Relatively short-lived, fast growing, medium-sized deciduous trees with broad, almost round leaves with uniform teeth. Two species are widespread in Wisconsin: quaking and big-tooth. Both have flattened petioles, and the trembling leaves that give the former species its name. Big-tooth aspen has more coarsely toothed leaves, and is a somewhat more valuable timber tree. Both are quick invaders of open ground, and both are very good pulpwood species. [031]
