General works providing comprehensive coverage of the gymnosperms include Thomas N. Taylor, Edith L. Taylor, and Michael Krings, The Biology and Evolution of Fossil Plants, 2nd ed. (2009), an excellent survey of fossil plants, including the history of the various gymnosperm groups and especially strong on the evolution of seeds; Charles Joseph Chamberlain, Gymnosperms: Structure and Evolution (1935, reprinted 1966), a classic description of the life history and morphology of all extant groups; K.U. Kramer and P.S. Green (eds.), Pteridophytes and Gymnosperms (1990), an overview of diversity and taxonomy of living gymnosperms.
