Leaves arranged in opposite decussate pairs, occasionally in whorls of three. Adult leaves scale-like, 1-2 mm. long (to 5 mm on lead shoots) and 1-1.5 mm. broad. Juvenile leaves on young seedlings needle-like, 5-10 mm. long. Seed cones berry-like, globose to bilobed, 6-9 mm. in diameter, dark blue with a pale blue-white waxy bloom, contain two seeds, rarely one or three. Pollen cones 2-4 mm. long, shedding pollen in early spring. Dioecious, producing cones of only one sex on each tree.
