Plant Anatomy is an introduction to the anatomical and histological structure of vegetative and reproductive plant organs. Descriptions of cells and tissues are accompanied by line drawings and light- and electron-micrographs. In recognition of modern research, which has brought to light so many transitional forms, the need for flexibility in the definitions of various elements and tissues is stressed throughout. Gaps in the current knowledge that await further research are identified. The book presents the basic structure and variability of the cells and tissues of vascular plants, as well as considering developmental, functional, evolutionary and ecological aspects. Plant Anatomy is not only a structured introduction to the subject; its review of current literature makes it a valuable reference. About 500 new references have been added, along with new drawings and micrographs.
