In this volume, the ninth of the series, treatments are offered for 52 families containing 432 genera belonging to 13 eudicot orders, many of which have recently been newly designed; four families remain unassigned to order. Emphasis is on the early-diverging eudicots and basal core eudicots the phylogenetic relationships and diversification of which have recently been in focus and are critically discussed. Systematically relevant information includes descriptions of families and genera, keys to the genera, and references to recent revisions. Introductions to the families provide...

When more than two decades ago this series was planned, classi?cation at the level of higher categories was rather contentious and considered to be of little concern for this book series. Through the advancement of molecular systematics within the last decade, the outlines of a phylogenetically based family scheme of angiosperms have become ava- able. This phylogenetic scheme for the ?rst time made meaningful broader comparisons feasible and is adopted here as a guideline for the circumscription of major blocks of families. However, due to the fragility of formal higher level classi?cation...

The original suggestion to organize a symposium about the classi fication and evolution of the Flowering Plants was made at, the International Botanical Congress at Leningrad in 1975, and the idea was so well accepted by several colleagues that plans for such a symposium quickly took shape. An organizing committee consisting of Professor H. MERXMULLER, Miinchen, Professor V. H. HEYWOOD, Reading, and Professor K. KUBITZKI, Hamburg, was set up. The conference took place on 7-12 September 197tl in the Institut fiir Allgemeine Botanik of the University of Hamburg under the auspices of the...
