Stature: 80-100 feet high; to 4 feet in diameter; with a rounded crown; branches large, heavy. Growing slowly, but reaching ages of over 500 years; in very old trees typically spreading laterally with huge lower branches and attaining trunk widths of as much as 7 feet.
Leaves: 5-9 inches long; with 7-9 deeply to shallowly carved, broad, rounded-off lobes; bright green and smooth on top, paler below.
Bark: Grayish; composed of loose plates; often with large, smooth patches (see illustration) resulting from attack by Aleurodiscus oakesii.
