outside of the cone, those toward its base produced into stout incurved knobs sometimes 

 armed with stout flattened spur-like often incurved spines, and on the inside of the cone 

 slightly flattened and armed with stout or slender straight prickles; often remaining closed 

 for several years and usually persistent on the stem and branches during the entire life 

 of the tree without becoming imbedded in the wood; seeds nearly triangular, j' long, 

 with a thin nearly black roughened shell, their wings broadest above the middle, oblique 

 at apex, nearly 1' long, ' wide. 



A tree, usually 40-50 but occasionally 90 high, with a trunk 2-3 in diameter, thick 

 spreading branches covered with dark scaly bark, in youth forming a regular pyramid, and 

 at maturity a handsome compact round-topped head of dense tufted foliage, and stout 

 branchlets dark orange-green at first, turning orange-brown more or less tinged with 

 purple. Bark of the lower part of the trunk often 4'-6' thick and deeply divided into long 

 narrow rounded ridges roughened by closely appressed dark purplish brown scales. Wood. 

 light, very strong, hard, rather coarse-grained, light brown, with thick nearly white sap- 

 wood; occasionally manufactured into lumber. 



Distribution. California coast region from Mendocino County southward, usually in 

 widely separated localities to Point Reyes Peninsula, north of the Bay of San Francisco, 

 and from Monterey to Coon Creek, San Luis Obispo County; in Lower California on 

 Cedros Island and on the west coast between Ensenada and San Quentin; of its largest 

 size and the common Pine-tree on the coast of Mendocino County. 



27. Pinus pungens Lamb. Table Mountain Pine. Hickory Pine. 



Leaves in crowded clusters, rigid, usually twisted, dark blue-green, \\'-%\' long, decidu- 

 ous during their second and third years. Flowers: male in elongated loose spikes, yellow; 

 female clustered, long-stalked. Fruit ovoid-conic, oblique at base by the greater de- 

 velopment of the scales 

 on the outer than on 

 the inner side, sessile, 

 reflexed, in clusters 

 usually of 3 or 4, or 

 rarely of 7 or 8, 2'-3' 

 long, becoming light 

 brown and lustrous, 

 with thin tough scales 

 armed with stout 

 hooked curved spines 

 produced from much 

 thickened mammillate 

 knobs, opening as soon 

 as ripe and gradually 

 shedding their seeds, 

 or often remaining 

 closed for two or three Fig. 34 



years longer, and fre- 

 quently persistent on the branches for eighteen or twenty years; seeds almost triangular, 

 full and rounded on the sides, nearly \' long, with a thin conspicuously roughened light 

 brown shell, their wings widest below the middle, gradually narrowed to the ends, 1' long, 

 \' wide. 



A tree, when crowded in the forest occasionally 60 high, with a trunk 2-3 in diameter, 

 and a few short branches near the summit forming a narrow round- topped head; in open 

 ground usually 20-30 tall, and often fertile when only a few feet high, with a short thick 

 trunk frequently clothed to the ground, and long horizontal branches, the lower pendulous 

 toward the extremities, the upper sweeping in graceful upward curves and forming a flat- 

 topped often irregular head, and stout branchlets, light orange color when they first appear,.
