Leaves needle-shaped, spirally alternate, spreading, per-, 

 sistent, and of a light green colour on the young plants ; those 

 on the adult trees scale-formed, closely inlaid, rounded on the 

 back, and concave on the inner face ; those on the hranchlets 

 much shorter, very close, and regularly imbricated ; those on 

 th'e larger branches longer, looser, decurrent at the base, and 

 tapering to an acute point, but sometimes rather obtuse. 

 Branches spread out horizontal, much divided, and furnished 

 with numerous laterals. Branchlets cylindrical, frequently 

 pendulous, and thickly covered with light-green glaucous 

 foliage, cone-bearing ones slightly thickened, and entirely 

 covered with scale-formed leaves closely imbricated, the upper 

 ones oval, and broadest at the base. Cones solitary on the 

 ends of the branchlets, two inches long, and more than one 

 inch in diameter, ovate, blunt-ended, and slightly tapering 

 towards both extremities. Scales in series, placed nearly at 

 right angles upon the axis of the cone, stipitate, thickened, and 

 enlarged from the point of insertion as far as the summit, which 

 is depressed and wrinkled on the external face, and furnished 

 with a small prickle in the centre of the little hollow. Seeds 

 from three to five under each scale, but mostly five. Seed- 

 leaves from three to six in number, but mostly in fours.
