A word generally referring to the surface region of a stem or a root. The term has a variable meaning and sometimes part or all of the bark is called rind. Occasionally the word is used as a substitute for periderm or for cork only. Most commonly, however, bark refers to all tissues external to the cambium (Fig. 1). If this definition is applied to stems having only primary tissues, it includes phloem, cortex and epidermis; the bark of roots of corresponding age would contain cortex and epidermis. More generally, the term bark is restricted to woody plants with secondary growth.
