中国甘蔗亚族几个容易混淆物种的订正

摘要

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 Chi-na.A new combination,Eulalia quadrinervis var.latifolia(Rendle)Y.C.Liu & H.Peng.,is represented here.Mi-crostegium ciliatum has been confused with M.fasciculatum for a while.Many plants of the latter species were misi-dentified as the former species.Even the discription in some domestic flora are not correct.This paper will clarify their key differences.%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Micro-stegium 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.
