Octavo, paperback,150 pp.,photographs, text illustrations. Cercidiphyllum is a relict angiosperm bringing to us a flavor of Cretaceous Period. Its reproductive morphology was interpreted, in the spirit of the dominant evolutionary paradigm, as inflorescences of reduced flowers represented by solitary pistils and groups of stamens. Evolutionary significance of Cercidiphyllum has long been anticipated despite the unpersuasive morphological interpretation and irrelevant paleobotanical evidence. This work was initially intended for paleobotanists who willingly compare their fossil material with the living Cercidiphyllum, using schematic descriptions and illustrations of traditional plant morphology. The idea behind this book was to provide an adequately illustrated material for such comparisons. Yet it turned out that there are more things in Cercidiphyllum than are dreamed of in our traditional plant morphology. Some of morphological findings of this study, such as the replacement of the floral structure by leafy shoots or the subtending bract-leaf conversion are relevant to the experimental evo-devoA" studies and bear on general problems of angiosperm evolution.
