as having &quot;pendulous, squarrose, cylindrical cones,&quot; which, with its quinate leaves, &quot;assimi 

 late it to P. strobus;&quot; but &quot;the seed, large and eatable, leaves not serrulate and stouter. 

 Dr. James, on the contrary, says his P.flexilis has, like P. strobus, leaves, 5 in a fascicle, but 

 beyond that there is little resemblance. &quot; The leaves are short and rigid, the sheaths short 

 and lacerated, the strobiles erect, composed of large unarmed scales, being somewhat smaller 

 than those of P. rigida, but similar in shape, and exuding a great quantity of resin/ &c. 



His description of the tree agrees well with that of the species under consideration, except that 

 he does not mention the white bark. The flexible branches and short leaves confined to the 

 extremities of the branches of P.flexilis are characters shared by most of the five-leaved pines, 

 which form a group by themselves, and should perhaps constitute a sub-genus. The red, 

 oblique-based resinless cones of our trees seem clearly to distinguish it. 



The wood of P.flexilis is white and soft, and not highly charged with resin, resembling that 

 of P. strobus and P. Lambertiana.
