• The tree's distinctive arborisation made it easily recognizable in the forest.
• Under the microscope, the arborisation of the blood vessels was clearly visible.
• The plant exhibited unusual arborisation, with branches spreading in multiple directions.
• Arborisation patterns in different species of trees can help botanists classify them.
• The nerve endings showed a fine arborisation as they approached the muscle tissue.
