A outer cylinder of meristematic tissue in plants that produces cork cells to replace the epidermis during secondary growth.
secondary area of cell division in the stems of woody plants that produces bark
The cork cambium is a synonym for phellogen. It is a cambium that forms in the cortex of the young stem and the pericycle of the young root. It then divides, as a typical cambium does, on both sides of the cambium. On the outer side about 4-5 layers of cells are formed. On the inside only one layer of cells is formed. The outer cells are called cork cells, the single inner layer is called phelloderm. All of these cells contain suberin, a waxy substance that makes the cork water proof. In the old stems, the cork cambium forms in the outer regions of the living phloem. DIAGRAMS: PHOTOS: 6-Year Tilia Stem

A layer of lateral meristematic tissue between the cork and the phloem in the bark of woody plants.

Secondary meristematic tissue in woody plants that forms the outer living covering of woody plants. This cambium produces the cork cells that, in their dead, mature state, protect the outside of the trunk and branches.
Cork cambium is a tissue found in many vascular plants as part of the periderm. The cork cambium is a lateral meristem and is responsible for secondary growth that replaces the epidermis in roots and stems. It is found in woody and many herbaceous dicots, gymnosperms and some monocots, which usually lack secondary growth.
