A conifer, but not a true cedar.
Close up of cedar bough
This evergreen tree, typically 40-60 feet tall, can attain 180 feet in the wild. It's short ascending branches droop at the tips.  
Native along the coast in southwestern Oregon (the town of Port Orford is in the center of its range) and in isolated areas of northwestern California, it is under attack by a root rot fungus, Phytophthora lateralis, which is devastating the species in the U.S.
Often confused with the so-called Alaskan cedar, this conifer has flattened frond-like twigs arranged horizontally which develop white "X" markings on the underside.   Male pollen cones develop on the tips of branchlets and are dark brown to red at pollen release.  Female flowers are inconspicuous, solitary, green to blue-green, and develop into seed cones that are round or spherical shape, blue-green then ripening to brown in the first season.
"lawsoniana" Named after Charles Lawson, a nurseryman in Edinburgh, Scotland, who raised it from the original introduction in 1845.
