Torrey's Pine {P. Torreyana, Parry) grows on a strip of 

 territory eight miles long and less than two miles wide along the 

 mouth of the Soiedad River in southern California, and on the 

 neighbouring Island of Santa Rosa. It is a nut pine with large, 

 thick, edible seeds upon which Indians and Mexicans formerly 

 subsisted, eating them raw or roasted. 



The tree is distinguished by its dark-green, tufted leaves, 

 which are 9 to 13 inches long, and cluster in fives in close 

 sheaths. The cones are abundant, oval, woody and heavy, the 

 scales set with stout recurving beaks.
