Reviews

"The editors make a realistic appeal for palynologists to go beyond mere static descriptive work by striving to interpret and analyze their data as part of broader systematic studies, and this aim is met. This study may serve as a model for quantifying data and more carefully justifying discontinuity of pollen character states in systematic studies. . . . this book would be worthy of selective reading to many, particularly those interested in development, land plant phylogeny, and application of new palynological techniques." --Science"The volume is characterized primarily by its diversity and wide range of topics." --American Association of Stratigraphic Palynologists Newsletter"Each themem is covered equally with many informative micrographs, tables, charts, and other graphics. . . . demonstrates the critical importance of palynogical techniques in increasing our understanding of developmental and systematic biology." --Cynthia M. Morton, Brittonia
