6. Genus: Picea
!
Spruces are large trees, from 20–60
metres (66–200 ft) tall
The needles, or leaves, of spruce trees
are attached singly to the branches in
a spiral fashion
The needles are shed when 4–10
years old, leaving the branches rough
Spruces are used as food plants
Scientists have found a cluster of
Norway Spruce in the mountains in
western Sweden

9. Genus: Juglans
An eastern North American tree having dark
brown wood and a deeply furrowed nut.
The wood of this tree is used especially for
veneer, cabinets, furniture, and gunstocks.
The nut of this tree, having an edible kernel used
especially in confections.
The black walnut is a large deciduous tree
attaining heights of 30–40 feet (9.1–12 m.
Fertile soils in mixed hardwood forests. Also
grows well in pastures, meadows, and slopes.

17. Genus: Quercus3
Oaks have spirally arranged leaves
The fruit is a nut called an acorn, borne in a cup-like
structure
Each acorn contains one seed (rarely two or three)
and takes 6–18 months to mature, depending on
species.
The live oaks are distinguished for being evergreen,
but are not actually a distinct group and instead are
dispersed across the genus.
Oak wood has a density of about 0.75 g/cm³, great
strength and hardness, and is very resistant to insect
and fungal attack

21. NorthernWhite Cedar

22. NorthernWhite Cedar
Genus: Thuja
This medium-sized tree grows to a height of 25
to 50 feet, and a diameter of 1 to 2 feet.
The thin bark sheds in long, narrow strips.
The only other North American member of this
group (the genus Thuja) grows in the West.
It typically is found growing on limestone soils in
moist to boggy habitats.
Brittle wood is used for fences, shingles and
small articles.
