This tree typically grows to 15-20 m tall, occasionally up to 25 m, and achieves a trunk diameter of 20-40 cm, rarely to more than 60 cm, and a narrow crown. It grows in a variety of habitats, from wetlands to ridgetops at altitudes of 100-1200 m. The mature bark ranges widely in color, from pure white to red, yellowish, pinkish, or gray. Bark of twigs, seedlings, and saplings is dark, from reddish to almost black, and covered with resin glands. The leaves are triangular-ovate, 3-8 cm long and 2-6 cm broad, with a truncate base and an acuminate apex, and a double-serrated margin. The fruiting catkins are 2-4 cm long and about 1 cm broad.
