Pine tree | Pinus roxburghii | Gymnosperms |

Pinus roxburghii, commonly known as Chir Pine, is a large, evergreen coniferous tree native to the Himalayan region. It is widely distributed across India, Nepal, Bhutan, and Pakistan, typically growing at altitudes between 500 to 2,000 meters. This species is well adapted to dry, rocky slopes and thrives in well-drained soils.

Chir Pine is a tall tree, reaching heights of 30–50 meters, with a straight trunk and rough, brown bark that peels in large scales. The needle-like leaves are arranged in clusters of three, measuring 15–35 cm in length, and have a bright green color.

Male Cone of Pinus

The male cone of Pinus is small, cylindrical, and occurs in clusters at the base of new shoots. It produces pollen grains containing male gametes. The cones are short-lived, shedding pollen in spring and then withering away. During shedding of pollen the forest covered with yellow cloud of pollen , known as sulphur shower. Wind pollination disperses the pollen to female cones for fertilization.

Female Cone of Pinus

The female cone of Pinus is larger, woody, and takes several years (3years) to mature. It consists of ovuliferous scales, each bearing two ovules. After pollination, it undergoes fertilization and seed development. When mature, it opens up to release winged seeds, aiding in wind dispersal for reproduction.

This species is economically important, as it produces high-quality resin, which is used to manufacture turpentine and varnish. The wood is lightweight, durable, and commonly used for construction, furniture, and paper production.
