Leaves in fascicles of 3-8, 10-45 cm - l n g> serrate ; resin-ducts medial ; outer walls of the 

 endoderm cells thick. Conelets subterminal, single or in clusters of 2-5, pedunculate, dull 

 pale brown, deep brown, dull black or blue, their scales armed with usually reflexed prickles. 

 Cones 6-25 cm. long, subsessile or pedunculate, symmetrical, subcylindrical or tapering, often 

 curved, opening at maturity, deciduous, their peduncles and a few basal scales often tempor- 

 arily persistent on the tree after the fall of the cone ; apophyses flat, pyramidal, tumid, or some- 

 what protuberant and reflexed, dull yellowish or reddish brown, fuscous brown or nearly black, 

 the prickles occasionally persistent. Branchlets somewhat pruinose, the decurrent bases of the 

 bracts prominent, persistent, and covered with an early-deciduous epiderm. Buds large, bright 

 ochre yellow, the male aments not apparent from the outline of the bud. 



A tree 15-20 metres high, varying in appearance with the length and thickness of its 

 leaves, and growing at all levels where Pines are found in Mexico and in the northern 

 states of Central America. The northern limit of its distribution is near the boundary between 

 the states of Durango and Chihuahua.
