The importance of Arthur Harry Church in both theoretical and practical aspects of botany is examined in this book, which collects together three of his many original and controversial contributions to Oxford Botanical Memoirs , including Thalassiophyta and the subaerial transmigration . Church was concerned with all aspects of plant evolution, painstakingly analysing floral structure, phyllotaxis, and algal life-cycles. This book includes some personal background on Church, and features some of his original plant sketches.
