The present paper is divided into three parts:
1. The first part is devoted to the review of the historical origin of the modern
classification systems of the flowering plants. Early systems of classification since the
Aristotelian time provided a basis for the modern schemes of classification. This paper
has reviewed briefly the history of plant systematics, which is divided into
three periods: the period of mechanical systems of classification, of natural systems of
classification, and of phylogenetic systems of classification. The historical development
of the plant systems and the basic idea for three periods is discussed respectively. This
paper also considers that the studies of the modern classification system have been entering a new period which primarily aims at overall evolutionary respects.
2. Comparison of the modern classification systems of the flowering plants. Four
main modern systems (i. e. A. Cronquist 1979, A. Takhtajan 1980, J. Hutchinson 1973
and A. Engler,s system as revised by H. Melchior in Engler,s Syllabus der Pflanzenfamilien 1964) which have greatly influenced the systemstics of plants are compared as
to their systematical principles, basic concepts and systematic positions of higher taxa
(orders and families) of the flowering plants. The paper is of the opinion that there
is still much important work to be done in every field.
3. A review for the modern classification systems of the flowering plants. The
paper reviews the modern classification of angiosperms from six aspects: a). The
flowers plants are originated from a common ancestral stock; b). The flowers of
angiosperms are homogeneous, stamen and carpel are phylletic sporangiophores,
all flowers of angiosperms are comparable; c). Monocotyledons are originated
from primitive dicotyledons, and represent phylogenetically monophyletic branch; d).
The idea advocating the subdivision of Dicotyledoneae into Lignosae and Herbaceae
should be rejected as pointed out by many authors; e). The systematical position of
Hamamelidae is still a crucial subject for further research; f). The evolutional trends
and evaluation of taxonomic characters must be considered in connection with the cor-relation to other characters in question.
