Populus grandidentata catkin L. Mellichamp catkin

A common tree of sandy soils, especially in dry cutover and burned areas, clearings, savannas, and forests, often with oaks and pines; persisting in mature deciduous forests.

Usually easily distinguished from P. tremuloides by the coarsely toothed leaves, densely white-silky when first expanding, and pubescent bud scales. The two species do, however, hybridize to form P. ×smithii B. Boivin; hybrids are known from Alpena, Cass, Ingham, Jackson, Midland, Monroe, Muskegon, Saginaw, and Washtenaw Cos. First generation hybrids are rather easily recognized, with leaves intermediate between those of the distinctive parent species.
