    United States of America. California. Glenn Co. North side of Alder Springs Road (Rt. 162), about 11.4 miles W of the intersection with Road 306, Mendocino National Forest.

  • Habitat

    In a young forest. Withy Arctostaphylos sp. (shrubb with gray leaves), Berberis sp., Ceanothus sp., Pinus ponderosa, Pseudostuga menziesii, Quercus chrysolepis and Quercus kelloggii. Locally aboundant (a nearly pure stand). On very gravelly loam over schist (Josephine gravelly loam, 30 to 50 percent slkopes; fine-loamy, mixed, mesic Typic Haploxerults).

  • Description

    Tree, 15 ft. x 2 inches. Young tree, 15 ft. tall, trunk diameter 2 inches. Trees similar in appearance to Casuarina, growth form also somehwhat similar to Pinus sabiniana, but smaller. Older trees with very narrow crowns, often with many vertical branches. Cone resin very fragrant, cones pointing downwards, persistent on trunk for perhaps 20 years, giving the trunk a barbed appearance. I had to twist the cones like knobs to get them to break off the tree. Phenology of specimen: Fruit.
