Walnut bark

Walnut bark. Cross section through the trunk of a walnut tree (Juglans regia) revealing the pattern in its bark. This pattern is known as a rhytidome. The rhytidome is composed of alternate layers of cork cells and dead cortical cells. Cork cells are produced in the stem by a layer of meristemetic cells (phellogen). Trees usually have one layer of phellogen, but in walnut there are several, which causes the pattern seen here

EDITORS COMMENTS
This print showcases the intricate beauty of walnut bark, providing a mesmerizing glimpse into the inner workings of a walnut tree. The cross section through the trunk of this majestic Juglans regia reveals an enchanting pattern known as a rhytidome. Composed of alternating layers of cork cells and dead cortical cells, this unique arrangement is truly awe-inspiring. Intriguingly, while most trees possess only one layer of phellogen (the meristematic cell layer responsible for producing cork cells), walnut trees boast several layers. This distinctive characteristic gives rise to the striking pattern that graces this photograph. The image not only highlights nature's artistic flair but also offers valuable insights into botany and biology. It serves as a testament to the complexity and diversity found within plant life, showcasing how even something as seemingly ordinary as bark can hold hidden wonders waiting to be discovered. With its rich wood tones and delicate grain, this slice from the walnut tree trunk captivates woodworking enthusiasts and cabinetmakers alike. Its biological intricacies make it an invaluable resource for those studying flora or interested in understanding more about plants at a microscopic level. This remarkable print by Science Photo Library invites us to appreciate the astonishing beauty that lies beneath our feet – reminding us that there is always more than meets the eye in nature's grand tapestry.
