Abstract

Axial parenchyma consists of axially elongate cells or more commonly strands of cells alive at maturity derived from fusiform cambial initials Axial parenchyma cells are usually thinner walled than the imperforate tracheary elements with which they are associated Each cell in a strand of axial parenchyma is usually surrounded by a secondary wall This definition excludes living fibers which have contents living at maturity but which tend to have thicker walls than axial parenchyma if septate living fibers are subdivided only by a primary wall cf Fig 46 parts 3 and 4
