A medium to large tree often growing in excess of 55' with a broad rounded crown.
Leaves: alternate, deciduous 4-5" in length and nearly as wide, deeply divided into 5-lobes with the lobes being widest at the ends, forming a cross shape. Dark green on the upper surface, paler and hairy below.
Flowers: male and female on the same tree appearing in spring when leaves are about one-third grown. Male catkins in drooping clusters about 5" in length, female flowers inconspicuous.
Fruit: oval acorn ripening in fall, about 1/2 - 1" in length set in a small cup covering about 1/3 of the acorn.
Twigs: stout and grayish to brown, rounded buds.
Bark: on mature trees thick and distinctive with deep fissures separated by dark gray ridges.
Comments: usually found on upland well drained sites, however; in S.E. Texas may tolerate some wetter or poorly drained areas. Larger trees are often stout twisted and gnarled. Good source of food for wildlife.
