Abstract: This work is continuation of two papers published by the present authors in 1998, in which our basic viewpoints on the phylogeny and evolution of angiosperms were presented. In this paper, a new outline of classification of the Magnoliophyta (angiosperms) is proposed. The Magnoliophyta are divided into 8 classes, 40 subclasses, 202 orders and 572 families. Among them, 22 new subclasses (Annonidae, Illiciidae, Ceratophyllidae, Lauridae, Calycanthidae, Chloranthidae, Aristolochiidae, Polygonidae, Plumbaginidae, Bromeliidae, Zingiberidae, Juncidae, Poaidae, Paeoniidae, Papaveridae, Trochodendridae, Betulidae, Malvidae, Ericidae, Myrtidae, Rutidae, Geraniidae) and 6 new orders (Degeneriales, Aizoales, Platanales, Dipentodontales, Meliosmales, Balanitales) are circumscribed. The number of genera and speciesin the families and each family’s geographical distribution are given.
