The base of a Yellow Birch trunk. In botany, the trunk (or bole) is the stem and main wooden axis of a tree, [1] which is an important feature in tree identification, and which often differs markedly from the bottom of the trunk to the top, depending on the species. The trunk is the most important part of the tree for timber production.

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. It grows as a spreading tree up to 20 m (70 ft) tall, with its trunk covered by a white, beige and grey thick papery bark.
A tree typically has many secondary branches supported clear of the ground by the trunk, which typically contains woody tissue for strength, and vascular tissue to carry materials from one part of the tree to another. For most trees the trunk is surrounded by a layer of bark which serves as a protective barrier.
As with other baobabs, Adansonia gregorii is easily recognised by the swollen base of its trunk, which forms a massive caudex, giving the tree a bottle-like appearance. [13] Boab ranges from 5–15 m (16–49 ft) in height, usually 9–12 m (30–39 ft), with a broad bottle-shaped trunk, [ 15 ] up to 5 m (16 ft) in diameter.
The tree is occasionally nicknamed the "Tree of Life" from the images of animals that are reputedly visible in the tree's gnarled trunk. As part of an official project local schoolchildren give tourists a tour of the tree and point out shapes of creatures on the trunk, including jaguars and elephants. [citation needed]
Alsophila manniana, synonym Cyathea manniana, the spiny tree fern or sheshino, is a species of tree fern. It is readily identified by the fierce spines on its trunk, and is widespread in the tropical regions of Africa.
Tree rings are the basis of dendrochronology, which dates wooden objects and associated artifacts. Dendroclimatology is the use of tree rings as a record of past climates. The aerial stem of an adult tree is called a trunk. The dead, usually darker inner wood of a large diameter trunk is termed the heartwood and is the result of tylosis. The ...
