Which branching pattern leads to a rounded shape with no dominant branch?

The branching pattern that results in a rounded shape with no dominant branch is known as deliquescent branching. This type of growth allows branches to spread out in a somewhat chaotic manner, resulting in a tree or plant form that does not feature a single, prominent leader branch. Instead, the branches grow in a way that gives the overall structure a rounded, full appearance. Deliquescent branching is common in many broadleaf trees, which tend to produce several branches that can all grow at similar rates, thus creating a more bushy and rounded canopy.

In contrast, other branching patterns, such as excurrent, typically feature a dominant central stem or leader that grows taller than the other branches. Columnar branching shapes often showcase more vertical growth with vertical branch arrangements. Secondary branching refers to the branches that develop from primary branches, but it doesn't specifically indicate the lack of a dominant branch nor does it imply a rounded shape.
