📙 First published in 1927, this volume looks in detail at Mycorrhiza, which refers to a symbiotic relationship between a fungus and the roots of a plant. Usually, this association is mutualistic, but can in some cases also be parasitic to the host plant. It looks at the history of the subject, exploring prominent theories and scientists, as well as contemporary understanding of the subject. This volume will appeal to those with an interest in botany and mycology, and it would make for a fantastic addition to collections of related literature. Contents include: "Introductory", "Historical", "The Early Period: 1840-1880", "Schleiden", "Reissek", "The Monotropa Controversy", "De Bary's Theory of Symbiosis", "The Second Period: 1880-1900", "Kamienski", etc. Many vintage books such as this are becoming increasingly scarce and expensive. We are republishing this book now in an affordable, modern, high-quality edition complete with a specially-commissioned new introduction on botany.
