PlNUS ToRREYANA TORREY PlNE, DEL MAR PlNE. 57 



based short or elongated spine-tipped umbos; cones generally breaking away 

 from the tree through their bases two or three years after maturity, so that a 

 few of the undeveloped scales are left on the peduncles attached to the branch; 

 seeds subovoid, about f in. long, yellowish brown with hard shell nearly y 1 ^ in. 

 thick, short thick dark-brown wing extending about ^ in. beyond the apex and 

 rich delicious kernel. 

 (The specific name, Torreyana, is in compliment to the botanist, Dr. John Torrey. 



This interesting tree, as usually seen on the bluff coast, is a very 

 low tree with wide-reaching branches, but in sheltered canons it 

 attains the height of 40 or 50 ft. (14 m.), with foliage conspicuously 

 arranged in large tufts at the extremities of the branchlets. The bark 

 of the trunk is of a rich brown color, rough with thick scaly ridges 

 which flake off in irregular scales. 



HABITAT. The Torrey Pine, the most limited in distribution of 

 all our Pines, is found close along the Pacific coast of California, 

 from a point within the extended city limits of San Diego northward 

 about eight miles to the San Dieguito River, and inland about a mile 

 and a half. Isolated from this locality by a distance of one hundred 

 and seventy-live miles to the northwestward, on the bluffs of the east- 

 ern end of the island Santa Rosa, is found another grove, the only one 

 known outside the range as above defined. 



PHYSICAL PROPERTIES. --Wood light, soft, not strong, coarse- 

 grained, and of a light reddish brown color, with thick yellowish- 

 white sap-wood. Specific Gravity, 0.4879; Percentage of Ash, 0.35; 

 Relative Approximate Fml Value, 0.4862; Coefficient of Elasticity, 

 54-213; j\L<><]ttJnx of Rupture, 756; Resistance to Longitudinal 

 Pressure, 290; I!<'xtx1<ince to Indentation, 147; Weight of a Cubic 

 Foot in r<tii<lx, 30.41. 



USES. The wood of this tree has been used for fuel, and its large 

 seeds, which are rich and delicious in flavor, are often gathered and 

 eaten raw or roasted. 



NOTE. The inroads upon this tree for fuel by irresponsible people 

 residing near it has been so great that .its extermination has been 

 greatly feared, but fortunately the city of San Diego has recently 

 passed an ordinance prohibiting the cutting of any of the trees within 

 the city limits under penalty of a heavy fine. As most of the existing 

 trees are in the city limits, as now extended, it is reasonable to expect 

 that the species will be perpetuated at least for a long time to come 

 in its native home.
