Trunks may have deeply fluted buttresses near the ground. Shumard oak is typically found in lowland areas and is able to survive where the soils experience flooding for six weeks of the year. [6] The young bark of the Shumard oak is light gray, very smooth, and very reflective. Shumard oak bark darkens and develops ridges and furrows as it ages.
Quercus palustris, also called pin oak, [4] swamp oak, or Spanish oak, [5] is a tree in the red oak section (Quercus sect.

Open-grown trees do not get as tall, but can develop a stouter trunk, up to 2 m (6 + 1 ⁄ 2 ft) in diameter. It has stout branches growing at right angles to the stem, forming a narrow round-topped head. [3] Under optimal conditions and full sun, northern red oak is fast growing and a 10-year-old tree can be 5–6 m (16–20 ft) tall. [4]
The red oaks of Mexico are one of the groups of oaks that have most rapidly diversified into different species. Molecular evidence suggests that there are significant numbers of undescribed Quercus species in Mexico, so the number of known species in the section is likely to be an underestimate of the total diversity.
