Archaeopteridophyta and Archaeospermatophyta divisio novum and their relations to some other groups of devonian plants

摘要

A significant isolation of archaeopterids within the class Progymnospermopsida Beck 1960 and division Polypodiophyta Takht. 1986 is shown. Archaeopteridophyta div.nov. and Archaeospermatophyta div.non. are presented. Archaeopteriophyta are considered as a blind phylum in the higher plant evolution which has not been directly related with oldest spermatophytes.
