| 摘要: |
| 通过标本研究和野外考察发现:被鉴定为二色金茅和滇南金茅的国产标本实际均为四脉金茅,且二色金茅和滇南金茅在国内无分布,国内各植物志中该名称下的类群应归入四脉金茅。另发表一新组合E. quadrinervis var. latifolia(Rendle)Y. C. Liu & H. Peng.; 国内各植物志和各大标本馆在描述和鉴定Microstegium ciliatum时,常与M. fasciculatum混淆,并在各种场合错误引证; 在此澄清二者真正的区别。 |

| Abstract: |
| Based on specimen examination and filedwork,specimens which have been identified as Eulalia siamensis and E. wightii were found to be E. quadrinervis. Therefore,E. siamensis and E. wightii are not distributed in China. A new combination,Eulalia quadrinervis var. latifolia(Rendle)Y. C. Liu & H. Peng.,is represented here.Microstegium ciliatum has been confused with M. fasciculatum for a while. Many plants of the latter species were misidentified as the former species. Even the discription in some domestic flora are not correct. This paper will clarify their key differences. |
