Secondary xylem
vascular cambium makes secondary xylem and phloem!!
Wood consists mostly of xylem cells, along with some cambium cells and phloem cells that appear as the 'growth rings' in wood cross-sections.
Bark makes up the phloem tissue and a cork cambium that protects the stem.

The bark
1. Normal type of secondary growth in the cortical and vascular regions adding to the secondary xylem ,secondary phloem and periderm at their proper places 2. Various types of anomalous secondary growth putting paches of xylem & phloem abnormally.
