 later weathered and grayish brown. The seeds and short wings 

 are very dark chocolate or blackish brown. Seed leaves /com.

 of scattered or open stands), dark yellowish brown, often tinged 

 with red; locally used for fuel. 



"lyittle is definitely known of the longevity of this pine. 

 It appears to attain its average full growth in from 60 to 80 

 years; trees from 20 to 24 inches in diameter are from 40 to 50 

 years old. Recurring fires, to which it has been subjected, seem 

 to prevent its longer survival. If permitted, it would probably 

 not attain an age of over 150 years except in a broken and de- 

 crepit form." 



This species is restricted to California occurring from the 

 northern part of the state in Humboldt and Shasta counties 

 to the mountains bordering the Mohave desert in Los Angeles 

 county, but is not found on the westward slope of the outer 

 Coast Range adjacent to the ocean. It prefers the hot and dry 

 slopes of the interior valleys where the rainfall is comparatively 

 scanty, although in places in the western part of its range it is 

 found within the fog belt, as about Alum Rock Park near San 

 Jose. Roughly, a chart of its distribution would include the 

 foothills and lower ridges surrounding the great interior valley, 

 where it occurs singly or in small groups, never forming forests, 

 up to an altitude of 4000 feet or more on some of the peaks of 

 the inner Coast Range. Seedlings come np and grow rapidly 

 under chaparral, but apparently need little or no shade. Since 

 the seeds are large and heavy, they are not usually carried any 

 considerable distance by the wind. 



According to Jepson (Fl. Cal. 1; 41), Douglas discovered 

 this tree "probably near San Juan Bautista," a mission situated 

 on the hills between Gilroy and Pajaro, and named it after his 

 friend, Captain Joseph Sabine, then secretary of the Horticul- 

 tural Society. 



The cones are, as originally described, "during the first year 

 rounded and bright green, when perfected the following Novem- 

 ber, elongated and brown."
