Bigtooth Aspen (Populus grandindentata)

Bigtooth Aspen or Poplar

The Bigtooth Aspen (Populus grandindentata) is a deciduous, dioecious angiosperm generally known in Maine as the "Poplar" but may also be called the Largetooth Aspen. It is a member of the Willow Family (Salicaceae). The genus name is Latin for "poplar." The species name means "large-toothed." The family name is from the Latin for "willow." It is used to make wood veneers and plywood.

The Poplar can grow to a height of 60 feet (18 meters) and have a trunk diameter of up to 1½ feet (½ meter). This tree is somewhat cylindrical with a narrow, pointed crown.

The leaves are ovate with rounded bases and short-pointed tips. The margins have coarse, curved teeth that distinguish this tree from other aspens in the area of French Hill Pond. The leaves are dull green on top and paler beneath. They turn pale yellow in the fall.

The Bigtooth Aspen is one of the first trees to grow after a forest fire, which accounts for its relatively large population in the area of French Hill Pond.

The minimum root depth of the Bigtooth Aspen is 20 inches (51 centimeters).
