A branch (UK /ˈbrɑːntʃ/ or UK /ˈbræntʃ/, US /ˈbræntʃ/) or tree branch (sometimes referred to in botany as a ramus) is a woody structural member connected to but not part of the central trunk of a tree (or sometimes a shrub). Large branches are known as boughs and small branches are known as twigs.
While branches can be nearly horizontal, vertical, or diagonal, the majority of trees have upwardly diagonal branches.
The term “twig” often refers to a terminus, while “bough” refers only to branches coming directly from the trunk. Read more
