Flashcards in Biology: Tree identification Deck (15):
Large tree, usually found near streams.
Bark is distinctive, made of plates that break off to expose patches of white and greenish bark underneath.
1” diameter balls that hang.
Thick, and dark green, even late in the fall. Bristle tipped, if you can find one that hasn’t been chewed on by a bug. Fruit is an acorn. Found at the edge of forests.
OK, the fruit gives this away, but know the leaves. In the fall, the black spots on the leaves helps. Turns bright yellow in autumn.
Found near edges.
Very blocky bark
Check the uneven base, double toothing.
Common as a seedling or small tree.
Grows well in many locations, often growing as a seedling where honeysuckle has shaded the oaks.
Often the largest trees in our forest are white oaks.
Rounded lobes on leaves
Seedlings are shade intolerant, do not survive long around honeysuckle
Actually 2 different species with very similar leaves but are easily distinguished by differences in the acorns.
Points on the ends of lobes (unlike white oak)
Compound, alternate leaves with nuts. There are several species in our forest.
Part of the nut crop.
Dominate indicator in our forests.
“U” shape between the lobes
Vibrant color in the fall
Note that there are four shapes often on one branch.
Deep blue berries are eaten early by birds
Very knobby “warty” bark
Also can be “weedy”, growing in locations where indicator trees are not doing well.
5 needles per bunch
Deeply lobed leaves
Pin stripes on acorns
Common planted tree in urban areas
Star shaped leaves (but careful not the sugar maple).
Gum balls are key signature
Native to Eastern North America
Showy white and pink flowers in early Spring
Red berries in fall.
Opposite, simple leaves with distinctive arching veins.
