A plant anatomy textbook unlike any other on the market today. Carol A. Peterson described the first edition as 'the best book on the subject of plant anatomy since the texts of Esau'. Traditional plant anatomy texts include primarily descriptive aspects of structure, this book not only provides a comprehensive coverage of plant structure, but also introduces aspects of the mechanisms of development, especially the genetic and hormonal controls, and the roles of plasmodesmata and the cytoskeleton. The evolution of plant structure and the relationship between structure and function are also discussed throughout. Includes extensive bibliographies at the end of each chapter. It provides students with an introduction to many of the exciting, contemporary areas at the forefront of research in the development of plant structure and prepares them for future roles in teaching and research in plant anatomy.
















substances. Cell walls are usually composed of two layers, an outer primary wall layer and an inner, thicker secondary wall layer (Fig. 2.26b). The thin primary wall is produced following mitosis and cell plate formation, and the secondary wall is added on to the inner surface of the primary wall as development of the cell proceeds. The secondary wall layer may be largely discontinuous, with secondary wall material deposited on the primary wall in helical, reticulate, or scalariform patterns, or

continue to provide support for the cells which thus maintain their function of transport. Ultimately, however, in many species, after death of the protoplast, continued elongation of the region and/or compression from the growth of surrounding cells results in the destruction of the protoxylem (Figs 6.4, 6.10c) and, in some species, the formation of protoxylem lacunae. Lacunae formed in this way are especially prominent in many taxa of monocotyledons (Fig. 6.4). The tracheary elements of the

inner surface of a provascular bundle (Fig. 6.9c) is referred to, especially in the older literature, as centripetal development whereas differentiation of the primary xylem from the inner toward the outer part of a bundle is referred to as centrifugal development (Figs 6.6b, c, 6.9c, e, 6.10c). This pattern of development of protoxylem in relation to metaxylem is also called endarch order of maturation of primary xylem. If the sequence of development of primary xylem tracheary elements is

As viewed in transverse section, a eustele appears as a cylinder of separate vascular bundles, some of which are axial bundles, others of which are leaf traces (Fig. 7.4). 125 126 SYMPODIAL SYSTEMS AND PATTERNS OF NODAL ANATOMY Figure 7.4 Transverse section of a eustele of a young stem of Helianthus.
