Floral morphology is key for understanding floral evolution and plant identification. Floral diagrams are two-dimensional representations of flowers that replace extensive descriptions or elaborate drawings to convey information in a clear and unbiased way. Following the same outline as the first edition, this comprehensive guide includes updated and relevant literature, represents the latest phylogeny, and features 28 new diagrams. Diagrams are presented in the context of the most recent classifications, covering a variety of families and illustrating the floral diversity of major groups of plants. A strong didactic tool for observing and understanding floral structures, these diagrams are the obvious counterpart to any genetic study in flowering plants and to the discussion of major adaptations and evolutionary trends of flowers. Floral Diagrams is invaluable for researchers and students working on plant structure, development and systematics, as well as being an important resource for plant ecologists, evolutionary botanists and horticulturists.

Louis P. Ronse De Craene is a botanist at the Royal Botanic Garden Edinburgh and the Director of the MSc course in the Biodiversity and Taxonomy of Plants. He has published more than 130 peer-reviewed papers and edited four books, and his main research interests are centred on floral morphology, the evolution of flowers and the use of floral characters in plant phylogeny. He has developed an internationally acclaimed expertise in floral structural morphology encompassing a broad range of angiosperm families.
Review of the first edition:
"This work suggests a strong potential synergy between morphological studies and evolutionary developmental genetics research, and will be a valuable reference for students or professionals in botany, plant systematics, and evoultionary developmental biology."
