The origin and evolution of land plants was an important event in the history of earth life and has affected all other lives on the earth and global environment. during the past two decade, the new discoveries of fossil plants microfossils and megafossils from the mid - ordovician through all silurian to the lower devonian improved knowledge of the origin of land plants, provided a time framework of the basal groups for the land plants and the early evolution diversity of vascular plants. three new plant based epochs have been recognized. on the other hand, molecular sequence studies have provided insights into the phylogeny and early branches of land plants. a phylogenetic tree has been established by the joint of a study of comparative morphology and gene sequences. this paper summarizes recent advances and new knowledges, comments on the phylogenetic studies based on the cladistic analysis
