摘　　要：菊科紫菀属为多系群和并系群,其地理分布类型复杂且具有较多的原始类群,是一个公认的分类困难类群。青藏高原紫菀属植物作为著名的藏药材,其基源复杂,导致紫菀入药品种混杂。文章采用文献查阅与实地踏查相结合的方法,对果洛地区采集到的7种紫菀属植物形态上的性状进行全面野外观察和拍照记录描述,并对《中国植物志(74)卷)》和《青海植物志》中7种紫菀的生长海拔、形态学描述存在的不完整之处进行补充或修正,为果洛地区紫菀属植物的分类以及为进一步全面合理的开发利用提供科学依据。Aster L.is a paraphyletic and polyphyletic group with complex and diverse geographical distribution types and numerous primitive taxa,and is recognized as a difficult classification group taxonomically.Aster as famous Tibetan medicinal herbs in Qinghai-Tibetan Plateau,its complex origin,coupled with differences in usage across different regions has led to confusion in the variety of Aster used as medicine.The aim of this study is to identify Aster L.species in the Guoluo Tibetan Autonomous Prefecture by investigating the morphological characteristics in the field combining with comprehensive description of photograph and the botanical properties of seven species of Aster L.The incompleteness in the growth altitude and morphological description of seven species of Aster in Flora of China(Volume 74)and Flora of Qinghai was supplemented and corrected.It provides scientific basis and guidance for the classification and further comprehensive utilization of Aster L.in the Guoluo area.
