Bark more or less red-brown. Branchlets in a horizontal plane. Shoots flattened. Leaves scale-like, shortly mucronate, triangular, upper surface green, whitish below, lateral scales of the same length as the facial ones, which have a glandular pit each; when crushed, foliage has an odour of rotting seaweed. Mature cones elliptic, 7-10(-12) mm long, 6-8(-9) mm across, composed of 10 to 14 scales with the outer surface brown, wrinkled and flat or slightly protuberant in the centre.
