vascular bundle

Science Dictionary
vascular bundle  
A strand of primary tissues found within the stem of a plant and consisting of xylem and phloem, along with cambium. The vascular bundles develop from the procambium of the growing stem. In the monocotyledons, vascular bundles are found in complex arrangements dispersed throughout the stem. In eudicotyledons, they are arranged in a ring, with the xylem of each bundle on the inside and the phloem on the outside. Also called fibrovascular bundle. See also fascicular cambium, interfascicular cambium.
