 obtuse angles, the leaf-scales or teeth small and acute.

 branchlets in diameter, cylindrical, oblong. Stamens in whorls of 

 3, imbricate in six vertical rows; apex scale-like, ovate or orbicular, 

 concave, with 2 anthers (2-celled) at the base. Female amenta 

 about 1 line in diameter, having 8 scales, solitary or 2 or 3 

 together, fairly numerous below the terminal drooping branchlets. 



Fruit-cones large, solitary, globular or compressed globular, 

 from i inch to 1^ in diameter or even larger: valves 6, very thick, 

 smooth or slightly rugose, furrowed at the junctions, the three 

 larger ones broadest at the middle and then tapering upwards 

 and very thick from the base to the middle, the smaller ones 

 about one-half as wide as the larger and shorter in length; the 

 dorsal point minute and close to the apex. Seeds dark-coloured, 

 the wings varying in size and shape.
