is Knobcone Pine (Pinus attenuata, Plate 6C), a species which 

 mostly occurs in inland localities and is particularly common on 

 burned-over lands. The cones of Knobcone Pine open during the 

 heat of a fire; thus, this species has a built-in mechanism that 

 allows it to re-seed itself after a fire. 



The closed-cone pines have an extensive fossil history which 

 provides an insight into their evolutionary background. The eco- 

 logical distinctiveness of the coastal species compared with Knob- 

 cone Pine is associated with the fact that the fossil record of
