Botanic information
Leaf: The reddish brown winter buds are ovoid-oblong up to 10 mm (? in) long with closely appressed scales. The stout linear keeled leaves are curved with a pungent acute apex and have stomatic bans on each surface. They arranged spirally and ascending on the other side of the pale yellow branchlets.
Flower: The monoecious flowers are pollinated by wind. The staminate (male) cylindrical red-purple pollen cones are arranged in groups of 1-3 towards the apex and the pale yellow-green narrowly ovoid woody pistillate (female) seed cones are pendent. They appear during late spring.
Fruit: The ovate to oblong seed cones mature to brown and are up to 45 mm (1µ in) wide. They have persistent obovate thin scales that are 20 mm (µ in) long by 18 mm (? in) wide and contain black to brown obovate winged seeds that are 6 mm (¥ in) long by 3 mm (? in)wide.
