The second volume of 'Die natürlichen Pflanzenfamilien' is presented now in the new format: the book contains an extensive General Part including contributions of different authors specializing in various fields of botany and it is written mainly in English. The first volume of this kind on the family Loganiaceae was published in 1980. The Ranunculaceae is a moderately large family with 59 genera and ca. 2500 species. Many of these have beautiful flowers or substances with strong physiological activity. They are used as ornamental or medicinal plants. This family shows great diversity in both vegetative and reproductive structures as well as in ecology. It retains many primitive characters and is regarded as one of the most primitive angiospermous families, but on the other hand it often presents quite specialized or advanced features. Therefore the family has attracted attention of many botanists from various points of view, and its members have been studied not only taxonomically, but also morphologically, anatomically, embryologically, palynologically, cytologically, phytochemically, serologically, and so on. Thus the Ranunculaceae are indeed an intensively studied family. The main author of this book, M. Tamura has been studying the family taxonomically for more than 40 years. In the history of the taxonomic studies of the Ranunculaceae, there were three monumental works. The first is that of A. P. De Candolle. In the first volume of his 'Systema Naturale' (1817) the family has been monographed at the species level for the first time. His work was excellent and gave a sound base to the taxonomy of the family and influenced the subsequent work for a long time. The second monograph at the generic level is that of K. Prantl (1888) which appeared in 'Die natürlichen Pflanzenfamilien'. This author used anatomical and embryological characters, in addition to traditional morphological ones for the classification of the family, and tried to make a phylogenetic sys

Angiosperms are the most diversi ed plant group in the world, being represented by ca 300,000 species in about 400 families. Like all of Life, including ourselves, they have had their own history and gone through many evolutionary stages before they arrived at their current forms. The origin of Angiospermae ( owering plants) has been the subject of much dispute because this is a key event in the history of life, and has a far-reaching in uence on our understanding of relationships among seed plants as a whole as well as within the angiosperms. Until recently most of palae- otanists recognized angiosperms only from the Cretaceous and younger strata. This contradicts the results of molecular analyses. I have been working on Mesozoic fossil plants for the past two decades, during which time I have studied a number of fossil plants. Some of these fossil plants have been published as Jurassic angiosperms, and, unsurprisingly, many questions and doubts have been raised about them. These questions need to be addressed se- ously and journal papers do not provide suf cient space to compare and relate these early angiosperms. In this book these pioneer angiosperms are documented in detail, sometimes with new specimens not studied before. Also, I propose a de nition of angiosperms that could be adopted in palaeobotany. My aim is to improve clarity and objectivity of judgment about what constitutes a fossil angiosperm.
