Quercus semecarpifolia is an evergreen tree up to 30 metres (98 feet) tall. The leaves are up to 12 centimetres (4+3⁄4 inches) long, with a few teeth along the sides but rounded at the tip. [3] [7] It has been grown in middle Europe, Western Germany, winter-hardiness zone 7, withstanding -14 °C, without any damages. It gives a good, showy bush to small tree with lush green leaves. The epithet semecarpifolia refers to a resemblance between the leaves of this species and those of Semecarpus anacardium. [7]
In its native range, it serves as a keystone species, exhibiting up to 80% dominance at elevations between 2700 and 3300 meters. [4] In areas where less degradation has occurred, Q. semecarpifolia reduces light at the forest floor, encouraging the growth of shade tolerant herbaceous species. [4] Local people make use of kharsu more frequently than other native oaks for food, animal fodder, fuel, and timber. [8] Its leaves are also known to support Antheraea proylei silk worms, goats, [9] and prevent slug infestations. [4]
