The Kashmir cypress ( Cupressus cashmeriana ) is a plant from the family of the cypress family (Cupressaceae). It is native to Bhutan . The existence of deposits in Northeast India is controversial.
description
The cashmere cypress grows as a small, evergreen tree which, in exceptional cases, can reach heights of up to 18 meters. It forms a conical to almost pyramidal crown . This consists of ascending branches and hanging twigs. The older, reddish-brown branches often no longer have any leaves after three or four years.
The scale-like leaves are mostly blue-green in color. However, this coloring can also be mixed with other colors. The protruding leaf tips are blunt.
The cones are rounded and have a diameter of around 12 millimeters. At first they are pale green and have bluish tires. As they ripen, they turn dark brown. They consist of ten cone scales, each bearing ten winged seeds.
distribution
The natural range of the Kashmir cypress includes Bhutan . It is controversial whether deposits also exist in the neighboring Indian states of Arunachal Pradesh and Sikkim . The species was also introduced into Tibet .
