The dark green leaves are 2 to 3 millimeters long. Her back is keeled. Young leaves are 10 to 15 millimeters long, have a pointed tip and often remain on older trees.

The male cones stand individually on the branches and are elongated with a length of up to 8 millimeters. The egg-shaped to conical, female cones stand individually, usually have a blue-green stem and are 2 to 3 centimeters thick. Each cone consists of six or eight thick cone scales and carries a few seeds. After ripening, they remain on the branches for several years before they release the seeds and fall. The chestnut-brown seeds are about 10 millimeters in size and have wings.
