The leaves are needle-like, flattened, 2.5-6 cm long and 2 mm wide by 0.5-1 mm thick, green to glaucous blue-green above, and with two glaucous blue-white bands of stomata below, and slightly notched to bluntly pointed at the tip. The leaf arrangement is spiral on the shoot, but with each leaf variably twisted at the base so they all lie in either two more-or-less flat ranks on either side of the shoot, or upswept across the top of the shoot but not below the shoot. The cones are 6-12 cm long and 4-4.5 cm broad, green or purple ripening pale brown, with about 100-150 scales; the scale bracts are short, and hidden in the closed cone. The winged seeds are released when the cones disintegrate at maturity about 6 months after pollination.
