Sawtooth oak is a large species, reaching a mature height of 70 feet. The leaves are similar to those of the chestnut but are smaller, 4-8 inches, and have pointed teeth. The acorns are also small in size, ranging from 5/8-3/4 inch long and are enclosed in cups with long, spreading, recurving scales. Approximately 2/3 of the nut is covered by the cup. Trees produce about 150 acorns per pound.
