 catkins composed of shield- shaped scale-like filaments bearing 2-4 anther-cells 

 under the lower margin. Fertile catkins globular, of shield-shaped scales bear- 

 ing several erect bottle-shaped ovules. Cone globular, firmly closed, but open- 

 ing at maturity ; the scales thick, pointed or bossed in the middle ; the few ox 

 several seeds attached to their contracted base or stalk. Cotyledons 2 or 3. — 

 Strong-scented evergreen trees, with very small and scale-like or some awl-

 and angular somewhat shield-shaped scales, bearing 2 angled seeds at their base. 

 Cotyledons 6-9. — Trees, with narrow linear 2-ranked light and deciduous
