CONE-BEARERS. 43 



form of the preceding species better deserves that 

 name on account of its half-inch, hemispherical 

 tubercles. First detected in the Santa Cruz Moun- 

 tains by Hartweg, 1846. 



A peculiarity of this tree is the tapering character of 

 its cones at base, whereby they oppose so little resistance 

 to the growing trunk that the annual layers, instead of 

 crowding off the cones (as happens to the broad-based 

 cones of other species in this group) often envelop them 

 completely. They are found in large trunks still-unopened 

 and preserving good seed. It emphasizes the importance 

 of this fact to state that the seeds of deciduous-coned 

 pines will not germinate after two years' keeping. 

 No. 24 Prickle-Cone Pine P- muricata, Don. 



Small, often slender, trees, usually in swampy 

 places, or on the wind-beaten bluffs along a limited 

 portion of the Coast Kange from Mendocino to 

 Lower California, mostly northward from 4 San Fran- 

 cisco. Rapid-growing trees. Bark on protected 

 trees, a little back from the sea, very hard and thick, 

 4 to 6 inches. Cones in whorls or circles, ovate, 2 

 to 3 inches long, with small tubercles and long, sharp, 

 persistent prickles. The cones have been known to 

 remain unopened for 20 to 30 years, then to release 

 good seeds. Leaves in pairs, usually long, 3 to 6 

 inches. This is one of the four storm-beaten Coast 

 pines of our western slope.
