Differences between the Pine Family and Cypress Family
Pine Family • Woody seed cone• Cone bract present, free
from cone scale• Cone scales overlap• Leaves needle like
Cypress Family• Seed cone woody or berry
like• Cone bract fused with cone
scale• Cone scales don’t overlap• Leaves needle, awl or scale
like

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

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

Pines produce pollen cones and seeds cones

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

Pseudotsuga menziesiiDouglas Fir
• Cones develop in one year
• No umbo on cone scale• Bract is longer than
cone scale

True cedars—the genus Cedrusdeciduous, upright cones, needles clusters on
short side shoots

Male (brown, papery, on the right)

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

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

Incense Cedar
• Seed cone woody and hangs down
• Cone scales in three pairs
• Middle cone scale fertile
• Produces 2 fertile seeds
