蒙古高原鸦葱属植物分类和地理分布研究

摘要

It was confirmed that there are 10 species and one variant of genus Scorzonera in the Mongolian plateau. Two species of S. manshurica Nakai. and S. ikonnikovii Lipsch et krasch are merged into S. austriaca Willd., and species of the S. sinensis was named as the S. austriaca Willd. variety. At the same time, compare with 《Flora Inner Mongolia》 (2ed. 4:1993), there are some revision and addition of the distribution area of some species of genus Scorzonera. Author consider that the species of S. muricullata Chang recorded in 《Flora Inner Mongolia》 (2ed. 4:1993) must be renamed as the H. polydicotoma (Ostonf.) H. L. Yang of Hexinia H. L. Yang. The geographical component of the genus Scorzonera was determined and the species key was complied.%确认了蒙古高原有鸦葱属植物10种；把Scorzonera ikonnikovii Lipsch. et Krasch.和 S. manshurica Nakai并入了S. austriaca Willd.；把S. sinensis Lipsch. et Krasch. 划为S. austriaca Willd 的一个变种；对《内蒙古植物志》（第2版，第4册）所描述的一些种的不确切分布进行了更正、补充；《内蒙古植物志》（第2版，第4册）记载的S. muriculata Chang 应为河西菊属Hexinia H. L. Yang的河西菊 H. polydicotoma (Ostenf.) H. L. Yang，该种在内蒙古没有分布；确定了蒙古高原鸦葱属植物的区系地理成分；编制了蒙古高原鸦葱属植物分种检索表。
