CONE-BEARERS. 37 



cahua Mountains of southeastern Arizona. Discov- 

 ered 1881 and 1892. 



(A wide extension of characters given to the cones 

 of the original P. latifolia, may make that species 

 include this Apache pine, but probably further inves- 

 tigation will determine that both forms are but vari- 

 eties of the polymorphous Pinus ponderosa.) 



Section Two -LATER ALE 3. 



LATERAL-CONED PINES. 



Cones arising laterally, i. e., along the bearing 

 stems, usually at some distance from the apex; mostly 

 not falling at maturity, but persisting, and either be- 

 coming inclosed by the later layers of wood, or the 

 peduncle is stretched and at length broken by the 

 enlargement of the tree, while the cone is often car- 

 ried outward confined in the bark, leaving a channel 

 behind it to the heart of the tree; hence the trees 

 make defective, pin-hole lumber. Leaves large and 

 long, 6 to 16 inches. Male flowers numerous, forming 

 ruffles about the branchlets at some distance from the 

 terminal bud, corresponding in position to that of the 

 cones.
