The contributions to the symposium on “New evidence for relationships and modern classifications in angiosperms” (held on 22 Aug 1981 during the XIII International Botanical Congress in Sydney) are surveyed, the present situation of this field of research is outlined. A ± monophyletic origin of the angiosperms is supported. Evidence for relationships among major taxa is still fragmentary and yet enormously expanding; synthetic efforts therefore become more and more imperative. A comparison of current classifications reveals similarities and convergencies, but also many areas of divergence and uncertainty. Ways towards a generally acceptable and more natural system of angiosperms are suggested.
