Khasi Pine - Description

Description

Pinus kesiya is a tree reaching up to 30–35 m tall with straight, cylindrical trunk. The bark is thick, dark brown, with deep longitudinal fissures. The branches are robust, red brown from the second year, the branchlets horizontal to drooping. The leaves are needle-like, dark green, usually 3 per fascicle, 15–20 cm long, the fascicle sheath 1–2 cm long and persistent. The cones are ovoid, 5–9 cm long, often curved downwards, sometimes slightly distorted; the scales of second-year cones are dense, the 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 mm long with a 1.5-2.5 cm wing. Pollination is in mid spring, with the cones maturing 18–20 months after.

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

Famous quotes containing the word description:

    Everything to which we concede existence is a posit from the standpoint of a description of the theory-building process, and simultaneously real from the standpoint of the theory that is being built. Nor let us look down on the standpoint of the theory as make-believe; for we can never do better than occupy the standpoint of some theory or other, the best we can muster at the time.
    Willard Van Orman Quine (b. 1908)

    To give an accurate description of what has never occurred is not merely the proper occupation of the historian, but the inalienable privilege of any man of parts and culture.
    Oscar Wilde (1854–1900)

    As they are not seen on their way down the streams, it is thought by fishermen that they never return, but waste away and die, clinging to rocks and stumps of trees for an indefinite period; a tragic feature in the scenery of the river bottoms worthy to be remembered with Shakespeare’s description of the sea-floor.
    Henry David Thoreau (1817–1862)
