and contain i or 2 resin-ducts near the middle of the upper face and i fibrovascu- 

 lar bundle; they are numerous and crowded towards the ends of the otherwise 

 naked twigs and persist for ten to twelve years or longer. The flowers appear in 

 June, the staminate in short, crowded clusters, oval, 12 mm. long, with darii orange- 

 red anthers. The pistillate flowers are scaly-stalked, nearly terminal, sohtary or in 

 pairs, oblong-oval, 8 mm. long, their scales broadly ovate, dark purple and with 

 long, slender tips. The cones are horizontal or somewhat pendent, ovoid, 6 to 10 

 cm. long, 4 cm. thick, dark purpHsh brown, nearly sessile, opening and dropping 

 their seed in September and October; their scales are thin, their tips somewhat 

 4-sided, but slightly thickened and ridged, the central elevated knob terminated 

 by a slender upcurved prickle often 18 mm. long, light reddish brown and very 

 brittle; the unexposed portion is dull red. The seed is nearly oval, 6 mm. long, 

 flattened, light brown and mottled with black; wing light brown, oblong, obUque, 

 about 8 mm. long and varying considerably in width; cotyledons 6 or 7. 



The wood is soft, weak, close-grained, and reddish; its specific gravity is about 

 0.56. It is sometimes used for mine timbers and for fuel. 



14. TORREY'S PINE — Pinus Torreyana Parry 



This is the most local and probably the rarest of the pines of our region, being 

 confined to an area of a very few square miles in San Diego county, California, 

 and to a small grove on Santa 

 Rosa Island. It attains a 

 height of 18 meters, with a 

 trunk diameter of 7.5 dm. 

 It is also called Soledad pine, 

 Del Mar pine, and Lone pine. 



The trunk is short with 

 stout spreading and ascend- 

 ing branches forming a nar- 

 row round top; in very 

 exposed posftions near the 

 ocean it is often contorted 

 and sometimes almost pros- 

 trate. The bark is about 2.5 

 cm. thick, irregularly and 

 deeply fissured into broad, 

 flat ridges, covered by large, 

 close, thin, light reddish 

 brown scales. The twigs are 



stout, often 2.1; cm. in diame- _ _ , .,.
