Quercus semecarpifolia is an Asian species of oak. It is native to the Himalayas and nearby mountains in Tibet, Afghanistan, India, Nepal, and Pakistan,[3] where it is referred to as kharsu.[4] It is classified in subgenus Cerris, section Ilex.[5][6]
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]
Fossil record
[edit]Fossils of Quercus semecarpifolia have been described from the fossil flora of Kızılcahamam district in Turkey, which is of early Pliocene age.[10]
