A critique on the "Eight-Class System" of the classification of Angiosperms proposed by Wu et al. (2002)

FU De_Zhi (Institute of Botany, the Chinese Academy of Sciences, Beijing 100093)  
Some critical comments are made on the "Eight_Classs System" of the classification of angiosperms recently proposed by Wu et al., which the authors claimed to be a "polyphyletic_ polychronic_polytopic" system. This system is established based on the hypothesis that there have existed eight principal lineages of angiosperms by the end of the Early Cretaceous. However, this hypothesis has not been supported by any neobotanical and paleobotanical evidence. The relationship among the eight lineages and their relationship with the common ancestor of angiosperms are not clearly clarified in the system. Having failed to follow the principle of common ancestry in the reconstruction of angiosperm phylogeny and having misinterpreted the concepts of monophyly and polyphyly, the "Eight_Class System" of the classification of angiosperms is considered to be an artificial one.
