Description
It is a medium-sized deciduous tree growing to 25–30 m tall with a trunk up to 1.5 m diameter. The bark is dark gray and deeply furrowed. The leaves are 8–20 cm long and 3–6 cm wide, with 14-20 small saw-tooth like triangular lobes on each side, with the teeth of very regular shape.
The flowers are wind-pollinated catkins. The fruit is an acorn, maturing about 18 months after pollination, 2–3 cm long and 2 cm broad, bicoloured with an orange basal half grading to a green-brown tip; the acorn cup is 1.5–2 cm deep, densely covered in soft 4–8 mm long 'mossy' bristles. It is closely related to the Turkey Oak, classified with it in Quercus sect. Cerris, a section of the genus characterised by shoot buds surrounded by soft bristles, bristle-tipped leaf lobes, and acorns that mature in about 18 months.

Famous quotes containing the word description:
“As they are not seen on their way down the streams, it is thought by fishermen that they never return, but waste away and die, clinging to rocks and stumps of trees for an indefinite period; a tragic feature in the scenery of the river bottoms worthy to be remembered with Shakespeare’s description of the sea-floor.”
—Henry David Thoreau (1817–1862)
“It is possible—indeed possible even according to the old conception of logic—to give in advance a description of all ‘true’ logical propositions. Hence there can never be surprises in logic.”
—Ludwig Wittgenstein (1889–1951)
“Everything to which we concede existence is a posit from the standpoint of a description of the theory-building process, and simultaneously real from the standpoint of the theory that is being built. Nor let us look down on the standpoint of the theory as make-believe; for we can never do better than occupy the standpoint of some theory or other, the best we can muster at the time.”
—Willard Van Orman Quine (b. 1908)
