Pinus kesiya (Khasi pine, Benguet pine or three-needled pine) is one of the most widely distributed

Burma, Cambodia, Laos, southernmost China, and Vietnam. It is an important plantation species elsewhere in the world, including in southern Africa and South America.[2][3]

The common name "Khasi pine" is from the Khasi hills in India, and "Benguet pine" is from the landlocked province of Benguet in Luzon, Philippines, where it is the dominant species of the Luzon tropical pine forests (known as saleng in Ilocano[4]). The Benguet pine is sometimes treated as a separate species, Pinus insularis; however, the current opinion is to treat these as conspecific with P. kesiya. The city of Baguio is nicknamed "The City of Pines", as it is noted for large stands of this tree.

Description

Bark of Benguet pine

Pinus kesiya is a

umbo a little convex, sometimes acutely spinous. The scales have transverse and longitudinal ridges across the middle of the scale surface. The seeds are winged, 6–7 millimetres (1⁄4–9⁄32 in) long with a 1.5–2.5 cm wing. Pollination occurs in mid-spring, with the cones maturing 18–20 months after.[citation needed
]

Khasi pine usually grows in pure stands or mixed with broad-leaved trees, but does not form open pine forests.[citation needed]

Uses

The soft and light

timber of Pinus kesiya can be used for a wide range of applications, including boxes, paper pulp, and temporary electric poles. It is intensely used for timber, both sourced in natural forests and plantations.[2][3]

The good-quality resin is not abundant and has not been much used except during the Spanish colonial period in the Philippines for the production of turpentine.[5]
