2982. Pinus rigida, recent cone. ( X Ji) 



young and easily raised from seed; grows on dry and 

 sterile soil. As an ornamental plant it may be used on 

 dry and rocky slopes, where it becomes often very 

 picturesque when older. It sprouts readily from stumps 

 if cut down or destroyed by fire, but the sprouts are 

 short-lived and never develop into trees.
