PINACEAE 



scale-tips rhomlioidal, bearing' a central prjckle with a broad base, or developed 

 into stout straightish or npwardly curving spurs ; seeds black, sometimes mottled, 

 the thin shell minutely roughened on the surface, 2V2 to 3 lines long, 



wings narrow, 5 to 8 lines long. 2V2 to 

 311. lines broad; cotyledons i tn 7. 



Low swampy lands or clay hills bor- 

 dering the sea : North Coast Kanges from 

 Ingleuook, ^Mendocino Co. (W.L.J, no. 

 2161) southward nearly to Bolinas, 

 attaining its best development on the 

 Sonoma coast; South Coast Ranges at 

 Monterey (Dr. Abbott; W.L.J, no. 

 2986) and San Luis Obispo Co.: Lower 

 California between Ensenada and San 

 Quentiu and on Cedros Island. Fire 

 type of pine, its cones remaining closed 

 10 to 20 years, or opening after a forest 

 tire and reseeding the area. Stands 

 dense but of very limited extent. First 

 discovered by Dr. Thos. Coulter in the 

 Santa Lucia ]Mts. near San Luis Obispo, 

 3,000 feet altitude and 10 miles from 

 the sea.

16. P. radiata Don. IMonterey Pine. (Fig. 6.) Beautiful, symmetrical 

 tree or in age with flattened or broken top, 30 to 70 or 115 feet high; foliage 

 rich dark green; trunk 1 to 4 feet in diameter; bark hard and more nearly black 

 than that of any other Californian pine; needles in 3s, or a few in 2s. 3 to (5 

 inches long; staminate catkins yellow, 20 to 40 in a cluster, conie-cylindrie. 6 or 

 7 lines long, the peduncles not exserted from the winter bud; ovulate catkins 

 peduncled, borne 2 to 5 in a whorl, 1 to 3 whorls formed on a shoot in a season; 

 cones tan-color or cinnamon, detlexed. sessile and unequally developed, broadly 

 ovoid and bluntly pointed, globose when open, 2V-; to 4i/'o inches long; scales on 

 the outer side toward the base conspicuously swollen at tip into a hemispherical 

 tubercle or boss and armed with a prickle which usually weathers off; seeds 

 black, minutely roughened on the surface. 3 lines long, bearing a broadly oblong 

 brown wing 2I/2 to 3 times as long; cotyledons 5 to 8. 



Near sea on south coast: about Pescadero, San Mateo Co.; ^Monterey (type 

 loc, Thos. Coulter) ; San Simeon Bay; Santa Rosa, Santa Cruz and Guadalupe 

 islands. Although naturally confined to a few localities of limited area, it 

 takes kindly to cultivation in all temperate regions of the earth and has a 

 wider horticultural distribution than any other Californian tree. It is com- 

 monly planted along the Pacific Coast for ornament and as a shelter tree but is 

 short-lived in the dry interior valleys.
