columnar branching
plant anatomy
Quick Summary
Columnar branching is a plant growth pattern where a central axis develops without any lateral branches until the apex of the main stem. This results in a distinct, unbranched trunk. This form is exemplified by palm trees. In contrast, other branching patterns include excurrent branching, common in conifers, which features a dominant trunk with smaller lateral branches, and deliquescent branching, seen in many oaks, where the central axis continually divides into branches of similar size, forming a crown.1
