Description
These trees can grow up to 40 meters tall, with a straight, column-like trunk that supports a narrow pyramidal or conical crown. The bark is smooth and gray on young trees, peeling in fine flakes, but as the tree ages, it becomes rough and fissured with a brownish-gray color.

The main branches are thick, relatively short, and spaced out, with the upper branches spreading outward or angling upward, while the lower ones may hang downward. The smaller twigs are slender but firm, with colors ranging from reddish-brown to purplish or even mahogany, depending on the tree. The newest shoots are smooth or have only very fine hairs in the grooves. The scars left behind when needles fall off are circular.

The buds are slightly sticky, shaped like elongated ovals, and measure between 6 and 8 millimeters long and 4 to 5 millimeters wide. Their outer scales are triangular, yellowish-brown, and remain on the tree for several years. The needles are arranged in a spiral pattern and appear crowded, with overlapping rows of varying lengths. The lower needles spread outward in a comb-like pattern, while those on cone-bearing branches tend to angle upward. They range from 1 to 4.5 centimeters long and 2 to 3.5 millimeters wide. At the base, they are slightly twisted, and their edges are flat rather than curled. The upper surface is glossy green, while the underside is pale whitish-green or bluish. The tips of needles on non-cone-bearing shoots are usually notched or slightly split, while those on cone-bearing branches are often more pointed. The undersides of the needles have two bands of stomata separated by a central ridge.

The pollen cones grow close together near the tips of branches, emerging from the axils of the needles. They are small, yellow, and have red pollen-producing structures. The seed cones grow upright on very short stalks and have an oval to oblong or cylindrical shape with a rounded or slightly depressed tip. They range from 5 to 9 centimeters long and 3 to 4 centimeters wide. When young, they are bluish-purple, later maturing into shades of purplish or reddish-brown.

The cone scales are wedge-shaped and fan-like, measuring 0.8 to 1.2 centimeters long and 1.5 to 2 centimeters wide at the middle of the cone. Their surface is smooth but has fine hairs, especially on exposed areas. The upper edge is rounded and unbroken, while the base narrows into a short stalk. The bracts inside the cone are obovate with a wedge-shaped base, measuring 1 to 1.5 centimeters long. They slightly extend beyond the cone scales and may have straight or recurved tips.

The seeds are small, oblong, and measure 5 to 6 millimeters long and 3 to 3.5 millimeters wide. Their color varies from dark brown to nearly black. Each seed is attached to a wing, which is wedge-shaped with an angled edge, measuring 6 to 7 millimeters long and 4 to 5 millimeters wide. The wings are nearly black.
