摘　要：摘　要：一般认为，蕨类植物是一群非常古老的植物，其演化历史可以追溯到4亿多年前。近十几年来，由于多种研究手段的应用，特别是分子系统学的异军突起，在蕨类植物起源演化方面取得了重要进展，使我们可以重新审视这一古老植物类群的演化历史。本文与传统观点相对比，简述了蕨类植物在分类范畴、起源演化及其重要类群间的系统演化关系方面的最新进展。

Abstract: Abstract: Pteridophytes as commonly defined have a longer evolutionary history with a fossil record of more than 400 million years. In the past 10 years, with the use of all available ways, especially the advances in molecular systematics, many important progress toward a more complete understanding of the circumscription、origin and evolution of Pteridophytes have been made, which gave us many new insights into the origin and evolution of Pteridophytes, compared to the traditional perspectives. 
Key words: Pteridophytes; origin; phylogeny
