Kingdom Plantae   >   Division Tracheophyta   >   Class Magnoliopsida   >   Order Fagales   >   Family Fagaceae   >   Genus Quercus   

Status:

Swamp White Oak typically grows in poorly drained soils of swamps and bottomlands. It is not a common tree but may be locally abundant. In Maryland, it occurs mostly on the coastal plain. Swamp White Oak is distributed from Minnesota south to Nebraska, east to North Carolina, and north to Quebec and Maine.

Description:

It is a medium to large tree, growing up to 100 feet tall. Leaves are commonly widest above the middle but may be narrowly elliptical. They have irregular margins, with 10-20 lobes and shallow sinuses. The upperside of the leaf is dark green, the underside has minute white hairs that give it a velvety feel. The difference in color between the two leaf surfaces accounts for the species epithet "bicolor". Bark is dark gray, with deep furrows and scaly or flat ridges. Acorns are single or in pairs, with the bowl-shaped, slightly fringed cup covering about one-third of the appoximately 1-inch-long nut.

Where to find:

The Federalsburgs wetlands trail along the Marshy Hope River in Caroline County.
