CRITIQUE

Description. Korean pine is an evergreen, coniferous species of tree which grows to mature heights of 100 feet (30 m) tall with a trunk up to 60 inches (150 cm) in diameter at breast height.

Bark is gray-brown and smooth, becoming gray-black, scaly, and peeling on larger trees.
    •    Shoots are red-brown, and densely puberulent.
    •    Needles are borne in fascicles of 5 at the end of a short shoot, 2.5 to 5 inches (6 – 13 cm) long and 0.06 inch (1 mm) wide, triangular in transverse section, dark green on outer face, with two inner faces that are whitish green with stomata.
    •    Pollen cones are ellipsoid in shape and develop crowded at base of new shoots.
    •    Seed cones are crowded near the ends of new shoots in groups of 1 to 5; conelets are green in color and ovoid in shape. They develop on a short peduncle and are green in color ovoid or cylindrical-ovoid in shape, 3.5 to 4.5 inches (9 – 11 cm) long and 2 to 2.5 inches (5 – 6 cm) broad with woody scales.
    •    Seeds are large, thickly triangular-obovoid in shape, wingless, and circa 0.9 inch (15 mm) long, 0.6 inch (10 mm) across, and 0.4 inch (7 mm) thick. Trees flower in May, with cones maturing in October of the following year.
