4. Pines - genus Pinus of the family Pinaceae
Most familiar of all conifers
About 90 species

5. Pine Leaves
Needles produced in clusters (fascicles) of 1 to 5

6. Pines produce pollen cones and seeds cones

7. Pines Seed cones take two years to develop
Umbo with or without prickle on each cone scale
Cone scales overlap in seed cones
Two seeds with wings on top of cone scale

8. Umbo on Cone Scale with prickle Ponderosa Pine

10. Pseudotsuga menziesii Douglas Fir

11. Pseudotsuga menziesii Douglas Fir
Seed Cone
Pollen Cone

12. Pseudotsuga menziesii Douglas Fir
Cones develop in one year
No umbo on cone scale
Bract is longer than cone scale

13. True cedars—the genus Cedrus deciduous, upright cones, needles clusters on short side shoots

14. Cones of true cedars (Cedrus)
Female (young, green, on the left)
Male (brown, papery, on the right)

15. Mature cones of true cedar
All the cone scales fall off, carrying the seeds away, leaving only the central axis (spike)

16. Atlas Cedar and Deodar Cedar
Needles in clusters on short side shoots
Cones develop each year, without a distinct umbo
Seed cones are upright
Seed cones fall apart when mature so seeds can disperse
