Description:In this book, the many facets of phyllotaxis are dealt with in an integrated manner. The author describes a unified concept of phyllotaxis, and presents a mathematical model of plant growth based on experimental, anatomical, cellular, physiological, and paleontological observations. The model not only provides a framework for formal analyses of botanical data, but also emphasizes the relevance of phyllotaxis to other structures, such as crystals, and proteins.
