The trunk consists of five main parts: The outer bark, inner bark , cambium, sapwood (live xylem), and heartwood (dead xylem).

The phloem is how the tree ...

Aleurodiscus oakesii on tree bark. Aleurodiscus oakesii is the most common fungi to cause “smooth patch disease” on the nonliving outer bark of trees. This fungal infection can lead to trees shedding and leaving smooth and lighter patches of bark on the tree, giving “smooth patch” its meaning.
A tree fork is a bifurcation in the trunk of a tree giving rise to two roughly equal diameter branches. These forks are a common feature of tree crowns. The wood grain orientation at the top of a tree fork is such that the wood's grain pattern most often interlocks to provide sufficient mechanical support.
Melaleuca quinquenervia, commonly known as the broad-leaved paperbark, paper bark tea tree, punk tree or niaouli, is a small- to medium-sized tree of the myrtle family, Myrtaceae.
