About Quercus john-tuckeri Nixon & C.H.Müll.
Quercus john-tuckeri is typically a bushy shrub that reaches 2 to 5 meters (6+1⁄2 to 16+1⁄2 feet) in height. It may occasionally grow into a tree-like form that exceeds 6 meters (20 feet) tall. Its mature branches are gray or brown. New twigs are covered in short woolly fibers, and develop a scaly texture as they age. This species produces evergreen leaves that are leathery, thick, and sometimes brittle. The leaves are gray-green, with a slightly paler lower surface. Leaf undersides are hairy, while upper leaf surfaces have less hair. Leaf blades are roughly oval in shape, have spine-like teeth along their edges, and measure less than 4 centimeters (1+1⁄2 inches) long. Its fruit is an acorn, with a thin cap that is 1 to 1.5 centimeters (3⁄8 to 5⁄8 inches) wide, and a nut that is 2 to 3 centimeters (3⁄4 to 1+1⁄8 inches) long.
