Bark, anatomy, cell structure, periderm, phloem


Samples of melaleuca bark were examined microscopically and their anatomical characteristics were illustrated. The observations revealed that each periderm is composed of layers of radially elongated thin-wall nonsuberized cells alternating radially with a flattened layer of suberized cells bearing casparian strips. Several periderms are formed during each growing season. These periderms alternate with the secondary phloem tissue, which contains fibers.
